I, James Phillips, stood with my back to the fire, smoking and
puzzling over it.  It was worth all the headlines the newspapers had
given it; there was no loophole to the mystery.

Both sides of the Atlantic knew Silas J. Ford.  He had established a
business reputation in America that had made him a celebrity in
England from the day he stepped off the liner.  Once in London his
syndicates and companies and consolidations had startled the
slow-moving British mind.  The commercial sky of the United Kingdom
was overshadowed by him and his schemes.  The papers were full of
praise and blame, of puffs and denunciations.  He was a millionaire;
he was on the verge of a smash that would paralyze the markets of the
world.  He was an abstainer, a drunkard, a gambler, a most religious
man.  He was a confirmed bachelor, a woman hater; his engagement was
to be announced shortly.  So was the gossip kept rolling with the
limelight always centred upon the spot where Silas J. Ford happened
to be standing.

And now he had disappeared, vanished, evaporated.

On the night of December 18, a Thursday, he had left London for
Meudon Hall, the fine old Hampshire mansion that he had rented from
Lord Beverley.  The two most trusted men in his office accompanied
him.  Friday morning he had spent with them; but at three o'clock the
pair had returned to London, leaving their chief behind.  From four
to seven he had been shut up with his secretary.  It was a hard time
for every one, a time verging upon panic, and at such times Silas J.
Ford was not an idle man.

At eight o'clock he had dined.  His one recreation was music, and
after the meal he had played the organ in the picture gallery for an
hour.  At a quarter past eleven he retired to his bedroom, dismissing
Jackson, his body servant, for the night.  Three-quarters of an hour
later, however, Harbord, his secretary, had been called to the
private telephone, for Mr. Ford had brought an extension wire from
the neighboring town of Camdon.  It was a London message, and so
urgent that he decided to wake his chief.  There was no answer to his
knock, and on entering the room he found that Mr. Ford was not in
bed.  He was surprised, but in no way suspicious, and started to
search the house.  He was joined by a footman, and, a little later,
by Jackson and the butler.  Astonishment changed to alarm.  Other
servants were roused to aid in the quest.  Finally, a party, provided
with lanterns from the stables, commenced to examine the grounds.

Snow had fallen early in the day, covering the great lawns in front
of the entrance porch with a soft white blanket, about an inch in
thickness.  It was the head groom who struck the trail.  Apparently
Mr. Ford had walked out of the porch, and so over the drive and
across the lawn toward the wall that bounded the public road.  This
road, which led from Meudon village to the town of Camdon, crossed
the front of Meudon Hall at a distance of some quarter of a mile.

There was no doubt as to the identity of the footprints, for Silas
Ford affected a broad, square-toed boot, easily recognizable from its
unusual impression.

They tracked him by their lanterns to the park wall, and there all
trace of him disappeared.  The wall was of rough stone, easily
surmountable by an active man.  The snow that covered the road
outside had been churned into muddy paste by the traffic of the day;
there were no further footprints observable.

The party returned to the house in great bewilderment.  The telephone
to London brought no explanation, and the following morning Mr.
Harbord caught the first train to town to make inquiries.  For
private reasons his friends did not desire publicity for the affair,
and it was not until the late afternoon, when all their
investigations had proved fruitless, that they communicated with
Scotland Yard.  When the papers went to press the whereabouts of the
great Mr. Ford still remained a mystery.

In keen curiosity I set off up the stairs to Inspector Peace's room.
Perhaps the little detective had later news to give me.

I found him standing with his back to the fire puffing at his
cigarette with a plump solemnity.  A bag, neatly shaped, lay on the
rug at his feet.  He nodded a welcome, watching me over his glasses.

"I expected you, Mr. Phillips," he said.  "And how do you explain it?"

"A love affair or temporary insanity," I suggested vaguely.

"Surely we can combine those solutions," he smiled.  "Anything else?"

"No.  I came to ask your opinion."

"My mind is void of theories, Mr. Phillips, and I shall endeavor to
keep it so for the present.  If you wish to amuse yourself by
discussing possibilities, I would suggest your consideration of the
reason why, if he wanted to disappear quietly, he should leave so
obvious a track through the snow of his own lawn.  For myself, as I
am leaving for Camdon via Waterloo Station in ten minutes, I shall
hope for more definite data before night."

"Peace," I asked him eagerly, "may I come with you?"

"If you can be ready in time," he said.

It was past two o'clock when we arrived at the old town of Camdon.  A
carriage met us at the station.  Five minutes more and we were clear
of the narrow streets and climbing the first bare ridge of the downs.
It was a desolate prospect enough--a bare expanse of wind-swept land
that rose and fell with the sweeping regularity of the Pacific swell.
Here and there a clump of ragged firs showed black against the snow.
Under that gentle carpet the crisp turf of the crests and the broad
plow lands of the lower ground alike lay hidden.  I shivered, drawing
my coat more closely about me.

It was half an hour later that we topped a swelling rise and saw the
gray towers of the ancient mansion beneath us.  In the shelter of the
valley by the quiet river, that now lay frozen into silence, the
trees had grown into splendid woodlands, circling the hall on the
further side.  From the broad front the white lawns crept down to the
road on which we were driving.  Dark masses of shrubberies and the
tracery of scattered trees broke their silent curves.  The park wall
that fenced them from the road stood out like an ink line ruled upon
paper.

"It must have been there that he disappeared," I cried, with a
speculative finger.

"So I imagine," said Peace.  "And if he has spent two nights on the
Hampshire downs, he will be looking for a fire to-day.  You have
rather more than your fair share of the rug, Mr. Phillips, if you
will excuse my mentioning it."

A man was standing on the steps of the entrance porch when we drove
up.  As we unrolled ourselves he stepped forward to help us.  He was
a thin, pale-faced fellow, with fair hair and indeterminate eyes.

"My name is Harbord," he said.  "You are Inspector Addington Peace, I
believe."

His hand shook as he stretched it out in a tremulous greeting.
Plainly the secretary was afraid, visibly and anxiously afraid.

"Mr. Ransome, the manager of Mr. Ford's London office, is here," he
continued.  "He is waiting to see you in the library."

We followed him through a great hall into a room lined with books
from floor to ceiling.  A stout, dark man, who was pacing it like a
beast in a cage, stopped at the sight of us.  His face, as he turned
it toward us, looked pinched and gray in the full light.

"Inspector Peace, eh?" he said.  "Well, Inspector, if you want a
reward, name it.  If you want to pull the house down, only say the
word.  But find him for us, or, by heaven, we're done."

"Is it as bad as that?"

"You can keep a secret, I suppose.  Yes--it couldn't well be worse.
It was a tricky time; he hid half his schemes in his own head; he
never trusted even me altogether.  If he were dead I could plan
something, but now--"

He thumped his hand on the table and turned away to the window.

"When you last saw Mr. Ford was he in good health?  Did he stand the
strain?"

"Ford had no nerves.  He was never better in his life."

"In these great transactions he would have his enemies.  If his plans
succeeded there would be many hard hit, perhaps ruined.  Have you any
suspicion of a man who, to save himself, might make away with Mr.
Ford?"

"No," said the manager after a moment's thought.  "No, I can not give
you a single name.  The players are all big men, Inspector.  I don't
say that their consciences would stop them from trying such a trick,
but it wouldn't be worth their while.  They hold off when jail is the
certain punishment."

"Was this financial crisis in his own affairs generally known?"

"Certainly not."

"Who would know of it?"

"There might be a dozen men on both sides of the Atlantic who would
suspect the truth.  But I don't suppose that more than four people
were actually in possession of the facts."

"And who would they be?"

"His two partners in America, myself, and Mr. Harbord there."

Peace turned to the young man with a smile and a polite bow.

"Can you add any names to the list?" he asked.

"No," said Harbord, staring at the detective with a puzzled look, as
if trying to catch the drift of his questions.

"Thank you," said the Inspector; "and now will you show me the place
where this curious disappearance occurred?"

We crossed the drive, where the snow lay torn and trampled by the
carriages, and so to the white, even surface of the lawn.  We soon
struck the trail, a confused path beaten by many footprints.  Peace
stooped for a moment, and then turned to the secretary with an angry
glance.

"Were you with them?" he said.

"Yes."

"Then why, in the name of common sense, didn't you keep them off his
tracks?  You have simply trampled them out of existence, between you."

"We were in a hurry, Inspector," said the secretary meekly.  "We
didn't think about it."

We walked forward, following the broad trail until we came to a
circular patch of trodden snow.  Evidently the searchers had stopped
and stood talking together.  On the further side I saw the footprints
of a man plainly defined.  There were some half-dozen clear
impressions and they ended at the base of the old wall, which was
some six feet in height.

"I am glad to see that you and your friends have left me something,
Mr. Harbord," said the Inspector.

He stepped forward and, kneeling down, examined the nearest footprint.

"Mr. Ford dressed for dinner?" he inquired, glancing up at the
secretary.

"Certainly!  Why do you ask?"

"Merely that he had on heavy shooting boots when he took this evening
stroll.  It will be interesting to discover what clothes he wore."

The Inspector walked up to the wall, moving parallel to the tracks in
the snow.  With singular activity for his plump and unathletic figure
he climbed to the top and seated himself while he stared about him.
Then on his hands and knees he began to crawl forward along the
coping.  It was a quaint spectacle, but the extraordinary care and
vigilance of the little man took the farce out of it.

Presently he stopped and looked down at us with a gentle smile.

"Please stay where you are," he said, and disappeared on the further
side.

Harbord offered me a cigarette, and we waited with due obedience till
the Inspector's bullet-head again broke the horizon as he struggled
back to his position on the coping of the wall.

He seemed in a very pleasant temper when he joined us; but he said
nothing of his discoveries, and I had grown too wise to inquire.
When we reached the entrance hall he asked for Jackson, the valet,
and in a couple of minutes the man appeared.  He was a tall,
hatchet-faced fellow, very neatly dressed in black.  He made a little
bow, and then stood watching us in a most respectful attitude.

"A queer business this, Jackson," said Addington Peace.

"Yes, sir."

"And what is your opinion on it?"

"To be frank, sir, I thought at first that Mr. Ford had run away; but
now I don't know what to make of it."

"And why should he run away?"

"I have no idea, sir; but he seemed to me rather strange in his
manner yesterday."

"Have you been with him long?"

"No, sir.  I was valet to the Honorable John Dorn, Lord Beverley's
second son.  Mr. Ford took me from Mr. Dorn at the time he rented the
Hall."

"I see.  And now will you show me your master's room?  I shall see
you again later, Mr. Harbord," he continued; "in the meanwhile I will
leave my assistant with you."

We sat and smoked in the secretary's room.  He was not much of a
talker, consuming cigarette after cigarette in silence.  The winter
dusk had already fallen when the Inspector joined us, and we retired
to our rooms to prepare for dinner.  I tried a word with Peace upon
the staircase, but he shook his head and walked on.

The meal dragged itself to an end somehow, and we left Ransome with a
second decanter of port before him.  Peace slipped away again, and I
consoled myself with a book in the library until half-past ten, when
I walked off to bed.  A servant was switching off the light in the
hall when I mounted the great staircase.

My room was in the old wing at the further side of the picture
gallery, and I had some difficulty in steering my way through the
dark corridors.  The mystery that hung over the house had shaken my
nerves, and I remember that I started at every creak of a board and
peered into the shadows as I passed along with, Heaven knows, what
ghostly expectations.  I was glad enough to close my door upon them
and see the wood fire blazing cheerfully in the open hearth.

I woke with a start that left me sitting up in bed, with my heart
thumping in my ribs like a piston rod.  I am not generally a light
sleeper, but that night, even while I snored, my nerves were active.
Some one had tapped at my door--that was my impression.

I listened with the uncertain fear that comes to the newly waked.
Then I heard it again--on the wall near my head this time.  A board
creaked.  Some one was groping his way down the dark corridor
without.  Presently he stopped, and a faint line of illumination
sprang out under my door.  It winked, and then grew still.  He had
lighted a candle.

Assurance came with the streak of light.  What was he doing, groping
in the dark, if he had a candle with him?  I crept over to the door,
opened it, and stared cautiously out.

About a dozen feet away a man was standing, a striking figure against
the light he carried.  His back was toward me, but I could see that
his hand was shading the candle from his eyes while he stared into
the shadows that clung about the further end of the corridor.

Presently he began to move forward.

The picture gallery and the body of the house lay behind.  The
corridor in which he stood terminated in a window, set deep into the
stone of the old walls.  The man walked slowly, throwing the light to
right and left.  His attitude was of nervous expectation--that of a
man who looked for something that he feared to see.

At the window he stopped, staring about him and listening.  He
examined the fastenings, and then tried a door on his right.  It was
locked against him.  As he did so I caught his profile against the
light.  It was Harbord, the secretary.  From where I stood he was not
more than forty feet away.  There was no possibility of a mistake.

As he turned to come back I retreated into my room, closing the door.
The fellow was in a state of great agitation, and I could hear him
muttering to himself as he walked.  When he had passed by I peeped
out to see him and his light dwindle, reach the corner by the picture
gallery, and fade into a reflection, a darkness.

I took care to turn the key before I got back into bed.

I woke again at seven, and, hurrying on my clothes, set off to tell
Peace all about it.  I took him to the place, and together we
examined the corridor.  There were only two rooms beyond mine.  The
one on the left was occupied by Ransome; that on the right was a
large store-room, the door of which was locked.  The housekeeper kept
the key, we learned upon inquiry.  Whom had Harbord followed?  The
problem was beyond me.  As for Inspector Peace, he did not indulge in
verbal speculations.

It was in the central hall that we encountered the secretary on his
way to the breakfast-room.  The man looked nervous and depressed; he
nodded to us and was passing on, when Peace stopped him.

"Good-morning, Mr. Harbord," he said.  "Can I have a word with you?"

"Certainly, Inspector.  What is it?"

"I have a favor to ask.  My assistant and myself have our hands full
here.  If necessary, could you help us by running up to London and--"

"For the day?" he interrupted.

"No.  It may be an affair of three or four days."

"Then I must refuse.  I am sorry, but--"

"Don't apologize, Mr. Harbord," said the little man, cheerfully.  "I
shall have to find some one else, that is all."

We walked into the breakfast-room, and a few minutes later Ransome
appeared with a great bundle of letters and telegrams in his hand.
He said not a word to any of us, but dropped into a chair, tearing
open the envelopes and glancing at their contents.  His face grew
darker as he read, and once he thumped his hand upon the table with a
crash that set the china jingling.

"Well, Inspector?" he said at last.

The little detective's head shook out a negative.

"Perhaps you require an incentive," he sneered.  "Is it a matter of a
reward?"

"No, Mr. Ransome; but it is becoming one of my personal reputation."

"Then, by thunder, you are in danger of losing it.  Why don't you and
your friend hustle instead of loitering around as if you were paid by
the job?  I tell you, man, there are thousands, hundreds of thousands
melting, slipping through our fingers, every hour of the day."

He sprang from his seat and started his walk again, up and down, up
and down, as we had first seen him.

"Shall you be returning to London?"

At the question the manager halted in his stride, staring sharply
down into the Inspector's bland countenance.

"No," he said; "I shall stay here, Mr. Addington Peace, until such
time as you have something definite to tell me."

"I have an inquiry to make which I would rather place in the hands of
some one who has personal knowledge of Mr. Ford.  Neither Mr. Harbord
nor yourself desire to leave Meudon.  Is there any one else you can
suggest?"

"There is Jackson, Ford's valet," said the manager, after a moment's
thought.  "He can go if you think him bright enough.  I'll send for
him."

While the footman who answered the bell was gone upon his errand we
waited in an uneasy silence.  There was the shadow of an ugly mystery
upon us all.  Jackson, as he entered, was the only one who seemed at
his ease.  He stood there, a tall figure of all the respectabilities.

"The Inspector here wishes you to go to London, Jackson," said the
manager.  "He will explain the details.  There is a fast train from
Camdon at eleven."

"Certainly, sir.  Do I return to-night?"

"No, Jackson," said Peace.  "It will take a day or two."

The man took a couple of steps toward the door, hesitated, and then
returned to his former place.

"I beg your pardon, sir," he began, addressing Ransome.  "But I would
rather remain at Meudon under present circumstances."

"What on earth do you mean?" thundered the manager.

"Well, sir, I was the last to see Mr. Ford.  There is, as it were, a
suspicion upon me.  I should like to be present while the search
continues, both for his sake--and my own."

"Very kind of you, I'm sure," growled Ransome.  "But you either do
what I tell you, Jackson, or you pack your boxes and clear out.  So
be quick and make up your mind."

"I think you are treating me most unfairly, sir.  But I can not be
persuaded out of what I know to be my duty."

"You impertinent rascal!--" began the furious manager.  But Peace was
already on his feet with a chubby hand outstretched.

"Perhaps, after all, I can make other arrangements, Mr. Ransome," he
said.  "It is natural that Jackson should consider his own reputation
in this affair.  That is all, Jackson; you may go now."

It was half an hour afterward, when the end of breakfast had
dispersed the party, that I spoke to Peace about it, offering to go
to London myself and do my best to carry out his instructions.

"I had bad luck in my call for volunteers," he said.

"I should have thought they would have been glad enough to get the
chance of work.  They can find no particular amusement in loafing
about the place all day."

"Doubtless they all had excellent reasons," he said with a smile.
"But, anyway, you can not be spared, Mr. Phillips."

"You flatter me."

"I want you to stay in your bedroom.  Write, read, do what you like,
but keep your door ajar.  If any one passes down the corridor, see
where he goes, only don't let him know that you are watching him if
you can help it.  I will take my turn at half-past one.  I don't mean
to starve you."

I obeyed.  After all, it was, in a manner, promotion that the
Inspector had given me; yet it was a tedious, anxious time.  No one
came my way, barring a sour-looking housemaid.  I tried to argue out
the case, but the deeper I got the more conflicting grew my theories.
I was never more glad to see a friendly face than when the little man
came in upon me.

The short winter's afternoon crept on, the Inspector and I taking
turn and turn about in our sentry duty.  Dinner-time came and went.
I had been off duty from nine, but at ten-thirty I poured out a
whisky and soda and went back to join him.  He was sitting in the
middle of the room smoking a pipe in great apparent satisfaction.

"Bed-time, isn't it?" I grumbled, sniffing at his strong tobacco.

"Oh, no," he said.  "The fact is, we are going to sit up all night."

I threw myself on a couch by the window without reply.  Perhaps I was
not in the best of tempers; certainly I did not feel so.

"You insisted on coming down with me," he suggested.

"I know all about that," I told him.  "I haven't complained, have I?
If you want me to shut myself up for a week I'll do it; but I should
prefer to have some idea of the reason why."

"I don't wish to create mysteries, Mr. Phillips," he said kindly;
"but believe me there is nothing to be gained in vague discussions."

I knew that settled it as far as he was concerned, so I nodded my
head and filled a pipe.  At eleven he walked across the room and
switched off the light.

"If nothing happens you can take your turn in four hours from now,"
he said.  "In the meanwhile get to sleep.  I will keep the first
watch."

I shut my eyes, but there was no rest in me that night.  I lay
listening to the silence of the old house with a dull speculation.
Somewhere far down in the lower floor a great gong-like clock chimed
the hours and quarters.  I heard them every one, from twelve to one,
from one to two.  Peace had stopped smoking.  He sat as silent as a
cat at a mousehole.

It must have been some fifteen minutes after two that I heard the
faint, faint creak of a board in the corridor outside.  I sat up,
every nerve strung to a tense alertness.  And then there came a sound
I knew well, the soft drawing touch of a hand groping in the darkness
as some one felt his way along the paneled walls.  It passed us and
was gone.  Yet Peace never moved.  Could he have fallen asleep?  I
whispered his name.

"Hush!"

The answer came to me like a gentle sigh.

One minute, two minutes more and the room sprang into sight under the
steady glow of an electric hand-lamp.  The Inspector rose from his
seat and slid through the door with me upon his heels.  The light he
carried searched the clustered shadows; but the corridor was empty,
nor was there any place where a man might hide.

"You waited too long," I whispered impatiently.

"The man is no fool, Mr. Phillips.  Do you imagine that he was not
listening and staring like a hunted beast?  A noisy board, a stumble,
or a flash of light, and we should have wasted a tiring day."

"Nevertheless he has got clear away."

"I think not."

As we crept forward I saw that a strip of the oak flooring along the
walls was gray with dust.  If it had been in such a neglected state
in the afternoon I should surely have noticed it.  In some curiosity
I stooped to examine the phenomenon.

"Flour," whispered the little man touching my shoulder.

"Flour?"

"Yes.  I sprinkled it myself.  Look--there is the first result."

He steadied his light as he spoke, pointing with his other hand.  On
the powdery surface was the half footprint of a man.

The flour did not extend more than a couple of feet from the walls,
so that it was only here and there that we caught up the trail.  We
had passed the bedroom on the left--yet the footprints still went on;
we were at the store-room door, yet they still were visible before
us.  There was no other egress from the corridor.  The tall window at
the end was, as I knew, a good twenty feet from the ground.  Had this
man also vanished off the earth like Silas Ford?

Suddenly the inspector stopped, grasping my arm.  The light he held
fell upon two footprints close together.  They were at right angles
to the passage.  Apparently the man had passed into the solid wall!

"Peace, what does this mean?"

You, sir, sitting peaceably at home, with a good light and an easy
conscience, may think I was a timid fool; yet I was afraid--honestly
and openly afraid.  The little detective heard the news of it in my
voice, for he gave me a reassuring pat upon the back.

"Have you never heard of a 'priest's hole'?" he whispered.  "In the
days when Meudon Hall was built, no country house was without its
hiding-place.  Protestants and priests, Royalists and Republicans,
they all used the secret burrow at one time or another."

"How did he get in?"

"That is what we are here to discover, and as I have no wish to
destroy Mr. Ford's old oak panels I think our simplest plan will be
to wait until he comes back again."

The shadows leaped upon us as Peace extinguished the light he
carried.  The great window alone was luminous with the faint
starlight that showed the tracery of its ancient stonework; for the
rest, the darkness hedged us about in impenetrable barriers.  Side by
side, we stood by the wall in which we knew the secret entrance must
exist.

It may have been ten minutes or more when from the
distance--somewhere below our feet, or so it seemed to me--there came
the faint echo of a closing door.  It was only in such cold silence
that we could have heard it.  The time ticked on.  Suddenly, upon the
black of the floor, there shone a thin reflection like the slash of a
sword--a reflection that grew into a broad gush of light as the
sliding panel in the wall, six feet from where we stood, rose to the
full opening.  There followed another pause, during which I could see
Peace draw himself together as if for some unusual exertion.

A shadow darkened the reflection on the floor, and a head came
peering out.  The light but half displayed the face, but I could see
that the teeth were bare and glistening, like those of a man in some
deadly expectation.  The next moment he stepped across the threshold.
With a spring like the rush of a terrier, Addington Peace was upon
him, driving him off his balance with the impact of the blow.  Before
I could reach them, the little detective had him down, though he
still kicked viciously until I lent a hand.  The click of the
handcuffs on his wrist ended the matter.

It was Ford's valet, the man Jackson.

We were not long by ourselves.  I heard a key turned in the lock, and
Ransome burst out of his room into the corridor like an angry bull.
Almost at the same moment there sounded a quick patter of naked feet
from behind us, and Harbord, the secretary, came running up, swinging
a heavy stick in his hand.  They both stopped at the edge of the
patch of light in which we were, staring from us to the gaping hole
in the wall.

"What in thunder are you about?" cried the manager.

"Finding a solution to your problem," said the little detective,
getting to his feet.  "Perhaps, gentlemen, you will be good enough to
follow me."

He stepped through the opening in the wall, and lifted the candle
which the valet had placed on the floor while he was raising the
panel from within.  By its light I could see the first steps of a
flight which led down into darkness.

"We will take Jackson with us," he continued.  "Keep an eye on him,
Mr. Phillips, if you please."

It was a strange procession that we made.  First Peace, with the
candle, then Ransome, with the valet, following, while I and Harbord
brought up the rear.  We descended some thirty steps, formed in the
thickness of the wall, opened a heavy door, and so found ourselves in
a narrow chamber, some twelve feet long by seven broad.  Upon a
mattress at the further end lay a man, gagged and bound.  As the
light fell upon his features, Ransome sprang forward, shouting his
name.

"Silas Ford, by thunder!"

With eager fingers we loosened the gag and cut the ropes that bound
his wrists.  He sat up, turning his long, thin face from one to the
other of us as he stretched the cramp from his limbs.

"Thank you, gentlemen," said he.  "Well, Ransome, how are things?"

"Bad, sir; but it's not too late."

He nodded his head, passing his hands through his hair with a quick,
nervous movement.

"You've caught my clever friend, I see.  Kindly go through his
pockets, will you?  He has something I must ask him to return to me."

We found it in Jackson's pocket-book--a check, antedated a week, for
five thousand pounds, with a covering letter to the manager of the
bank.  Ford took the bit of stamped paper, twisting it to and fro in
his supple fingers.

"It was smart of you, Jackson," he said, addressing the bowed figure
before him: "I give you credit for the idea.  To kidnap a man just as
he was bringing off a big deal--well, you would have earned the
money."

"But how did you get down here?" struck in the manager.

"He told me that he had discovered an old hiding-place--a 'priest's
hole,' he called it--and I walked into the trap as the best man may
do sometimes.  As we got to the bottom of that stairway he slipped a
sack over my head and had me fixed in thirty seconds.  He fed me
himself twice a day, standing by to see I didn't halloo.  When I paid
up he was to have twenty-four hours' start; then he would let you
know where I was.  I held out awhile, but I gave in to-night.  The
delay was getting too dangerous.  Have you a cigarette, Harbord?
Thank you.  And who may you be?"

It was to the detective he spoke.

"My name is Peace, Inspector Addington Peace, from Scotland Yard."

"And I owe my rescue to you?"

The little man bowed.

"You will have no reason to regret it.  And what did they think had
become of me, Inspector?"

"It was the general opinion that you had taken to yourself wings, Mr.
Ford."

It was as we traveled up to town next day that Peace told me his
story.  I will set it down as briefly as may be.

"I soon came to the conclusion that Ford, whether dead or alive, was
inside the grounds of Meudon Hall.  If he had bolted, for some
reason, by the way, which was perfectly incomprehensible, a man of
his ability would not have left a broad trail across the centre of
his lawn for all to see.  There was, moreover, no trace of him that
our men could ferret out at any station within reasonable distance.
A motor was possible, but there were no marks of its presence next
morning in the mud of the roads.  That fact I learned from a curious
groom who had aided in the search, and who, with a similar idea upon
him, had carefully examined the highway at daybreak.

"When I clambered to the top of the wall I found that the snow upon
the coping had been dislodged.  I traced the marks, as you saw, for
about a dozen yards.  Where they ended I, too, dropped to the ground
outside.  There I made a remarkable discovery.  Upon a little drift
of snow that lay in the shallow ditch beneath were more footprints.
But they were not those of Ford.  They were the marks of long and
narrow boots, which led into the road, where they were lost in the
track of a flock of sheep that had been driven over it the day before.

"I took a careful measurement of those footprints.  They might, of
course, belong to some private investigator; but they gave me an
idea.  Could some man have walked across the lawn in Ford's boots,
changed them to his own on the top of the wall, and so departed?  Was
it the desire of someone to let it be supposed that Ford had run away?

"When I examined Ford's private rooms I was even more fortunate.
From the boot-boy I discovered that the master had three pairs of
shooting boots.  There were three pairs in the stand.  Some one had
made a very serious mistake.  Instead of hiding the pair he had used
on the lawn, he had returned them to their place.  The trick was
becoming evident.  But where was Ford?  In the house or grounds, dead
or alive, but where?

"I was able, through my friend the boot-boy, to examine the boots on
the night of our arrival.  My measurements corresponded with those
that Jackson, the valet, wore.  Was he acting for himself, or was
Harbord, or even Ransome, in the secret?  That, too, it was necessary
to discover before I showed my hand.

"Your story of Harbord's midnight excursion supplied a clue.  The
secretary had evidently followed some man who had disappeared
mysteriously.  Could there be the entrance to a secret chamber in
that corridor?  That would explain the mystification of Harbord as
well as the disappearance of Silas Ford.  If so, Harbord was not
involved.

"If Ford were held a prisoner he must be fed.  His jailer must of
necessity remain in the house.  But the trap I set in the suggested
journey to town was an experiment singularly unsuccessful, for all
the three men I desired to test refused.  However, if I were right
about the secret chamber I could checkmate the blackmailer by keeping
a watch on him from your room, which commanded the line of
communications.  But Jackson was clever enough to leave his
victualing to the night-time.  I scattered the flour to try the
result of that ancient trick.  It was successful.  That is all.  Do
you follow me?"

"Yes," said I; "but how did Jackson come to know the secret hiding
place?"

"He has long been a servant of the house.  You had better ask his old
master."
