utter immobility of countenance of a red Indian, and I could
not gather from his appearance whether he was satisfied or not with
the position of the case. His conversation, I remember, was about the
Bertillon system of measurements, and he expressed his enthusiastic
admiration of the French savant.

We found our client still under the charge of his devoted nurse, but
looking considerably better than before. He rose from the sofa and
greeted us without difficulty when we entered.

"Any news?" he asked, eagerly.

"My report, as I expected, is a negative one," said Holmes. "I have seen
Forbes, and I have seen your uncle, and I have set one or two trains of

slept without a nurse in the room. I was so much better that I thought
I could dispense with one. I had a night-light burning, however. Well,

suddenly aroused by a slight noise. It was like the sound which a mouse
makes when it is gnawing a plank, and I lay listening to it for some
time under the impression that it must come from that cause. Then it
grew louder, and suddenly there came from the window a sharp metallic
snick. I sat up in amazement. There could be no doubt what the sounds
were now. The first ones had been caused by some one forcing an
instrument through the slit between the sashes, and the second by the
catch being pressed back.

"There was a pause then for about ten minutes, as if the person were
