“Burroughs,” he said at last, “every one who is interested in Joseph Crawford’s death has suspected Gregory Hall, except one person.  Not everybody said they suspected him, but they did, all the same.  Even Miss Lloyd wasn’t sure that Hall wasn’t the criminal.  Now, there’s just one person who declares that Hall did not do it, and that he is not implicated.  Why should this person feel so sure of Hall’s innocence?  And, furthermore, my boy, here are a few more important questions.  In which drawer of the desk was the revolver kept?”

“The upper right-hand drawer,” I replied.

“I mean, what else was in that drawer?”

“Oh, important, valuable memoranda of Mr. Crawford’s stocks and bonds.”

“Do you mean stock certificates and actual bonds?”

“No; merely lists and certain data referring to them.  The certificates themselves were in the bank.”

“And the will—­where had that been kept?”

“In a drawer on the other side of the desk.  I know all these things, because with the lawyer and Mr. Philip Crawford, I have been through all the papers of the estate.”

“Well, then, Burroughs, let us build up the scene.  Mr. Joseph Crawford, after returning from his lawyer’s that night, goes to his office.  Naturally, he takes out his will, that he thinks of changing, and—­we’ll say—­it is lying on his desk when Mr. Lemuel Porter calls.  He talks of other matters, and the will still lies there unheeded.  It is there when Miss Lloyd comes down later.  She has said so.  It remains there until much later —­when Philip Crawford comes, and, after discovering that his brother is dead, sees the will still on the desk and takes it away with him, and also sees the pistol on the desk, and takes that, too.  Now, granting that the murderer came between the time Miss Lloyd left the office and the time Philip Crawford came there, then it was while the murderer was present that the drawer which held the pistol was opened, the pistol taken out, and the murder committed, Since Mr. Joseph Crawford showed no sign of fear of violence, the murderer must have been, not a burglar or an unwelcome intruder, but a friend, or an acquaintance, at least.  His visit must have been the reason for opening that drawer, and that not to get the pistol, but to look at or discuss the papers contained in that drawer.  The pistol, thus disclosed, was temptingly near the hand of the visitor, and, for some reason connected with the papers in that drawer, the pistol was used by the visitor—­suddenly, unpremeditatedly, but with deadly intent at the moment.”

“But who—­” I began.

“Hush,” he said, “I see it all now—­or almost all.  Let us go to Philip Crawford’s at once—­before it is time to go to Miss Lloyd’s.”

We did so, and Fleming Stone, in a short business talk with Mr. Crawford, learned all that he wanted to know.  Then we three went over to Florence Lloyd’s home.
