or him there. He returned
to Dartmoor and awaited the arrival of the baronet."

"One moment!" said I. "You have, no doubt, described the sequence
of events correctly, but there is one point which you have left
unexplained. What became of the hound when its master was in
London?"

"I have given some attention to this matter and it is undoubtedly
of importance. There can be no question that Stapleton had a
confidant, though it is unlikely that he ever placed himself in
his power by sharing all his plans with him. There was an old
manservant at Merripit House, whose name was Anthony. His
connection with the Stapletons can be traced for several years,
as far back as the schoolmastering days, so that he must have
been aware that his master and mistress were really husband and
wife. This man has disappeared and has escaped from the country.
It is suggestive that Anthony is not a common name in England,
while Antonio is so in all Spanish or Spanish-American countries.
The man, like Mrs. Stapleton herself, spoke good English, but
with a curious lisping accent. I have myself seen this old man
cross the Grimpen Mire by the path which Stapleton had marked
out. It is very probable, therefore, that in the absence of his
master it was he who cared for the hound, though he may never
have known the purpose for which the beast was used.

"The Stapletons then went down to Devonshire, whither they were
soon followed by Sir Henry and you. One word now as to how I
stood myself at that time. It may possibly recur to your memory
that when I examined the paper upon which the printed words were
fastened I made a close inspection for the water-mark. In doing
so I held it within a few inches of my eyes, and was conscious of
a faint smell of the scent known as white jessamine. There are
seventy-five perfumes, which it is very necessary that a criminal
expert should be able to distinguish from each other, and cases
have more than once within my own experience depended upon their
prompt recognition. The scent suggested the presence of a lady,
and already my thoughts began to turn towards the Stapletons.
Thus I had made certain of the hound, and had guessed at the
criminal before ever we went to the west country.

"It was my game to watch Stapleton. It was evident, however, that
I could not do this if I were with you, since he would be keenly
on his guard. I deceived everybody, therefore, yourself included,
and I came down secretly when I was
