"Won't you tell me what you mean? You may trust me." "Yes, I am sure I may," he said, promptly. "And I think I will tell you--though I have never breathed it to mortal yet. I think Matilda did it herself." Backing away from the counter in my surprise, I upset an empty milk-can. "Matilda!" I exclaimed, picking up the can. "Mr. Johnny, with all my heart I believe it to have been so. I have believed it for some time now." "But the girls were too friendly to harm one another. I remember you said so yourself, Owen." "And I thought so then, sir. No suspicion of Matilda had occurred to me, but rather of the man I had seen there on the Wednesday. I think she must have done it in a sudden passion; not of deliberate purpose." "But now, what are your reasons?" "I told you, sir, as I daresay you can recall to mind, that I should do what lay in my power to unravel the mystery--for it was not at all agreeable to have it laid at my door. I began, naturally, with tracing out the doings of that night as connected with No. 7. Poor Jane Cross had not been out of doors that night, and so far as I knew had spoken to no one save to me from the window; therefore of her there seemed nothing to be traced: but of Matilda there was. Inquiring here and there, I bit by bit got a few odds and ends of facts together. I traced out the exact time, almost to a minute, that I rang twice at the door-bell at No. 7, and was not answered; and the time that Matilda entered the Swan to get the supper beer. Pretty nearly half an hour had elapsed between the first time and the second." "Half an hour!" "Not far short of it. Which proved that Matilda must have been indoors when I rang, though she denied it before the coroner, and it was taken for granted that I had rung during her absence to fetch the beer. And you knew, sir, that her absence did not exceed ten minutes. Now why did not Matilda answer my ring? Why did she not candidly say that she had heard the ring, but did not choose to answer it? Well, sir, that gave rise to the first faint doubt of her: and when I recalled and dwelt on her singular manner, it appeared to me that the doubt might pass into grave suspicion. Look at her superstitious horror of No. 7. She never would go into the house afterwards!" I nodded. "Two or three other little things struck me, all tending to strengthen my doubts, but perhaps they are hardly worth naming. Still, make the worst of it, it was only suspicion, not certainty, and I left Saltwater, holding my tongue." "And is this all, Owen?" "Not quite, sir. Would you be so good as to step outside, and just look at the name over the grocer's door?" I did so, and read Valentine. "John Valentine." The same name as Matilda's.
