stooped behind the low wall which surrounded
the stunted orchard. Creeping in its shadow I reached a point whence I
could look straight through the uncurtained window.

There were only two men in the room, Sir Henry and Stapleton. They sat
with their profiles towards me on either side of the round table. Both
of them were smoking cigars, and coffee and wine were in front of them.
Stapleton was talking with animation, but the baronet looked pale and
distrait. Perhaps the thought of that lonely walk across the ill-omened
moor was weighing heavily upon his mind.

As I watched them Stapleton rose and left the room, while Sir Henry
filled his glass again and leaned back in his chair, puffing at his
cigar. I heard the creak of a door and the crisp sound of boots upon
gravel. The steps passed along the path on the other side of the wall
under which I crouched. Looking over, I saw the naturalist pause at the
door of an out-house in the corner of the orchard. A key turned in
a lock, and as he passed in there was a curious scuffling noise from
within. He was only a minute or so inside, and then I heard the key turn
once more and he passed me and reentered the house. I saw him rejoin his
guest, and I crept quietly back to where my companions were waiting to
tell them what I had seen.

"You say, Watson, that the lady is not there?" Holmes asked when I had
finished my report.

"No."

"Where can she be, then, since there is no light in any other room
except the kitchen?"

"I cannot think where she is."

I have said that over the great Grimpen Mire there hung a dense, white
fog. It was drifting slowly in our direction and banked itself up like a
wall on that side of us, low but thick and well defined. The moon shone
on it, and it looked like a great shimmering ice-field, with the heads
of the distant tors as rocks borne upon its surface. Holmes's face
was turned towards it, and he muttered impatiently as he watched its
sluggish drift.

"It's moving towards us, Watson."

"Is that serious?"

"Very serious, indeed--the one thing upon earth which could have
disarranged my plans. He can't be very long, now. It is already ten
o'clock. Our success and even his life may depend upon his coming out
before the fog is over the path."

The night was clear and fine above us. The stars shone cold and bright,
while a half-moon bathed the whole scene in a soft, uncertain light.
Before us lay the dark bulk of the house, its serrated roof
