He took a small piece of torn paper from a notebook and spread it out upon his knee.

"This was found between the finger and thumb of the dead man. It appears to be a fragment torn from a larger sheet.

You will observe that the hour mentioned upon it is the very time at which the poor fellow met his fate.

You see that his murderer might have torn the rest of the sheet from him or he might have taken this fragment from the murderer. It reads almost as though it were an appointment." Holmes took up the scrap of paper, a facsimile of which is here reproduced.

"Presuming that it is an appointment," continued the inspector, "it is of course a conceivable theory that this William Kirwan, though he had the reputation of being an honest man, may have been in league with the thief.

He may have met him there, may even have helped him to break in the door, and then they may have fallen out between themselves." "This writing is of extraordinary interest," said Holmes, who had been examining it with intense concentration. "These are much deeper waters than I had thought." He sank his head upon his hands, while the inspector smiled at the effect which his case had had upon the famous London specialist.

"Your last remark," said Holmes presently, "as to the possibility of there being an understanding between the burglar and the servant, and this being a note of appointment from one to the other, is an ingenious and notentirely impossible supposition. But this writing opens up... " He sank his head into his hands again and remained for some minutes in the deepest thought.

When he raised his face again I was surprised to see that his cheek was tinged with colour, and his eyes as bright as before his illness. He sprang to his feet with all his old energy.

"I'll tell you what," said he, "I should like to have a quiet little glance into the details of this case. There is something in it which fascinates me extremely.

If you will permit me, Colonel, I will leave my friend Watson and you, and I will step round with the inspector to test the truth of one or two little fancies of mine. I will be with you again in half an hour." An hour and a half had elapsed before the inspector returned alone.
