believe that I will succeed in discovering Mr. Hosmer Angel."

Mr. Windibank gave a violent start and dropped his gloves. "I am
delighted to hear it," he said.

"It is a curious thing," remarked Holmes, "that a typewriter has
really quite as much individuality as a man's handwriting. Unless
they are quite new, no two of them write exactly alike. Some
letters get more worn than others, and some wear only on one
side. Now, you remark in this note of yours, Mr. Windibank, that
in every case there is some little slurring over of the 'e,' and
a slight defect in the tail of the 'r.' There are fourteen other
characteristics, but those are the more obvious."

"We do all our correspondence with this machine at the office,
and no doubt it is a little worn," our visitor answered, glancing
keenly at Holmes with his bright little eyes.

"And now I will show you what is really a very interesting study,
Mr. Windibank," Holmes continued. "I think of writing another
little monograph some of these days on the typewriter and its
relation to crime. It is a subject to which I have devoted some
little attention. I have here four letters which purport to come
from the missing man. They are all typewritten. In each case, not
only are the 'e's' slurred and the 'r's' tailless, but you will
observe, if you care to use my magnifying lens, that the fourteen
other characteristics to which I have alluded are there as well."

Mr. Windibank sprang out of his chair and picked up his hat. "I
cannot waste time over this sort of fantastic talk, Mr. Holmes,"
