was the tutor's
room. Above were three students, one on each story. It was already
twilight when we reached the scene of our problem. Holmes halted and
looked earnestly at the window. Then he approached it, and, standing on
tiptoe with his neck craned, he looked into the room.

"He must have entered through the door. There is no opening except the
one pane," said our learned guide.

"Dear me!" said Holmes, and he smiled in a singular way as he glanced
at our companion. "Well, if there is nothing to be learned here, we had
best go inside."

The lecturer unlocked the outer door and ushered us into his room. We
stood at the entrance while Holmes made an examination of the carpet.

"I am afraid there are no signs here," said he. "One could hardly hope
for any upon so dry a day. Your servant seems to have quite recovered.
You left him in a chair, you say. Which chair?"

"By the window there."

"I see. Near this little table. You can come in now. I have finished
with the carpet. Let us take the little table first. Of course, what has

first, and he copied it. How long would it take him to do that, using
every possible contraction? A quarter of an hour, not less. Then he
tossed it down and seized the next. He was in the midst of that when
your return caused him to make a very hurried retreat--VERY hurried,
since he had not time to replace the papers which would tell you that he
had been there. You were not aware of any hurrying feet on the stair as
you entered the outer door?"

"No, I can't say I was."

"Well, he wrote so furiously that he broke his pencil, and had, as you
observe, to sharpen it again. This is of interest, Watson. The pencil
was not an ordinary one. It was above the usual size, with a soft lead,
the outer colour was dark blue, the maker's name was printed in silver
lettering, and the piece remaining is only about an inch and a half
long. Look for such a pencil, Mr. Soames, and you have got your man.
When I add that he possesses a large and
