"Then, ma'am," he declared, with a quick change of manner, meant, I should judge, to put me in my proper place, "I do not think we can depend upon the accuracy of your memory;" and he made a motion as if to leave.

As I did not know whether his apparent disappointment was real or not, I let him move to the door without a reply. But once there I stopped him.

"Mr. Gryce," said I, "I don't know what you think about this matter, nor whether you even wish my opinion upon it. But I am going to express it, for all that. I do not believe that Howard killed his wife with a hat-pin."

"No?" retorted the old gentleman, peering into his hat, with an ironical smile which that inoffensive article of attire had certainly not merited. "And why, Miss Butterworth, why? You must have substantial reasons for any opinion you would form."

"I have an intuition," I responded, "backed by certain reasons. The intuition won't impress you very deeply, but the reasons may not be without some weight, and I am going to confide them to you."

"Do," he entreated in a jocose manner which struck me as inappropriate, but which I was willing to overlook on account of his age and very fatherly manner.

"Well, then," said I, "this is one. If the crime was a premeditated one, if he hated his wife and felt it for his interest to have her out of the way, a man of Mr. Van Burnam's good sense would have chosen any other spot than his father's house to kill her in, knowing that her identity could not be hidden if once she was associated with the Van Burnam name. If, on the contrary, he took her there in good faith, and her death was the unexpected result of a quarrel between them, then the means employed would have been simpler. An angry man does not stop to perform a delicate surgical operation when moved to the point of murder, but uses his hands or his fists, just as Mr. Van Burnam himself suggested."

"Humph!" grunted the detective, staring very hard indeed into his hat.

"You must not think me this young man's friend," I went on, with a well meant desire to impress him with the impartiality of my attitude. "I never have spoken to him nor he to me, but I am the friend of justice, and I must declare that there was a note of surprise in the emotion he showed at sight of his wife's hat, that was far too natural to be assumed."

The detective failed to be impressed. I might have expected this, knowing his sex and the reliance such a man is apt to place upon his own powers.
