Mr. Gryce continued to stare into the vase.

"Miss Butterworth,"—it was the Inspector who was speaking,—"I have been told that you take great interest in the Van Burnam murder, and that you have even gone so far as to collect some facts in connection with it which you have not as yet given to the police."

"You have heard correctly," I returned. "I have taken a deep interest in this tragedy, and have come into possession of some facts in reference to it which as yet I have imparted to no living soul."

Mr. Gryce's interest in my poor little vase increased marvellously. Seeing this, I complacently continued:

"I could not have accomplished so much had I indulged in a confidant. Such work as I have attempted depends for its success upon the secrecy with which it is carried on. That is why amateur work is sometimes more effective than professional. No one suspected me of making inquiries, unless it was this gentleman, and he was forewarned of my possible interference. I told him that in case Howard Van Burnam was put under arrest, I should take it upon myself to stir up matters; and I have."

"Then you do not believe in Mr. Van Burnam's guilt? Not even in his complicity, I suppose?" ventured the Inspector.

"I do not know anything about his complicity; but I do not believe the stroke given to his wife came from his hand."

"I see, I see. You believe it the work of his brother."

I stole a look at Mr. Gryce before replying. He had turned the vase upside down, and was intently studying its label; but he could not conceal his expectation of an affirmative answer. Greatly relieved, I immediately took the position I had resolved upon, and calmly but vigorously observed:

"What I believe, and what I have learned in support of my belief, will sound as well in your ears ten minutes hence as now. Before I give you the result of such inquiries as I have been enabled to make, I require to know what evidence you have yourself collected against the gentleman you have just named, and in what respect it is as criminating as that against his brother?"
