"There must be other witnesses who can testify to that," answered the detective, with the perceptible irritation of one weary of a subject which he feels he has already amply discussed.
"Well," declared the other, dropping his eyes from the young man's countenance to a sheet of paper he was holding in his hand, "whatever rôle this humpback has played in the tragedy now occupying us, whether he be a wizard, a secret accomplice, a fool who cannot keep his own secret, or a traitor who cannot preserve that of his tools, this affair, as you call it, is not likely to prove the simple matter you seem to consider it. The victim, if not her townsfolk, knew she possessed an enemy, and this half-finished letter which I have found on her table, raises the question whether a common tramp, with no motive but that of theft or brutal revenge, was the one to meditate the fatal blow, even if he were the one to deal it."

We have many sorts and kinds of detectives in our bureau. Some for one kind of business, some for another; the following up of a criminal is not mine."
"What, then, is yours?" asked the coroner, not yielding a jot of his determination.
The detective was silent.
"Read the letter," persisted Dr. Tredwell, shrewdly conscious that if once the young man's professional instinct was aroused, all the puerile objections which influenced him would immediately vanish.
There was no resisting that air of command. Taking the letter in his hand, the young man read:
