"Most certainly."
"And know, perhaps, who that hunchback was?"
"Yes."
"You will not be surprised, then, if I recall to you the special incidents of that hour. A group of lawyers, among them Mr. Orcutt, are amusing themselves with an off-hand chat concerning criminals and the clumsy way in which, as a rule, they plan and execute their crimes. All seem to agree that a murder is usually followed by detection, when suddenly a stranger speaks and tells them that the true way to make a success of the crime is to choose a thoroughfare for the scene of tragedy, and employ a weapon that has been picked up on the spot. What happens? Within five minutes after this piece of gratuitous information, or as soon as Mr. Orcutt can cross the street, Mrs. Clemmens is found lying in her blood, struck down by a stick of wood picked up from her own hearth-stone. Is this chance? If so, 'tis a very curious one."
"I don't deny it," said Doctor Tredwell.
"I believe you never did deny it," quickly retorted the detective. "Am I not right in saying that it struck you so forcibly at the time as to lead you into supposing some collusion between the hunchback and the murderer?"
"It certainly did," admitted the coroner.
"Very well," proceeded Mr. Gryce. "Now as there could have been no collusion between these parties, the hunchback being no other person than myself, what are we to think of this murder? That it was a coincidence, or an actual result of the hunchback's words?"
Dr. Tredwell and Mr. Ferris were both silent.
"Sirs," continued Mr. Gryce, feeling, perhaps, that perfect openness was necessary in order to win entire confidence, "I am not given to boasting or to a too-free expression of my opinion, but if I had been ignorant of this affair, and one of my men had come to me and said: 'A mysterious murder has just taken place, marked by this extraordinary feature, that it is a precise reproduction of a supposable case of crime which has just been discussed by a group of indifferent persons in the public street,' and then had asked me where to look for the assassin, I should have said: 'Search for that man who heard the discussion through, was among the first to leave the group, and was the first to show himself upon the scene of murder.' To be sure, when Byrd did come to me with this story, I was silent, for the man who fulfilled these conditions was Mr. Orcutt."
