"Then we had the visit from our friends next morning, shadowed always by Stapleton in the cab. From his knowledge of our rooms and of my appearance, as well as from his general conduct, I am inclined to think that Stapleton's career of crime has been by no means limited to this single Baskerville affair. It is suggestive that during the last three years there have been four considerable burglaries in the west country, for none of which was any criminal ever arrested. The last of these, at Folkestone Court, in May, was remarkable for the cold-blooded pistolling of the page, who surprised the masked and solitary burglar. I cannot doubt that Stapleton recruited his waning resources in this fashion, and that for years he has been a desperate and dangerous man.
"We had an example of his readiness of resource that morning when he got away from us so successfully, and also of his audacity in sending back my own name to me through the cabman. From that moment he understood that I had taken over the case in London, and that therefore there was no chance for 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
