"Never mind," I interrupted. "You must let my words go in one ear and out of the other after you have answered them. I wish"—here I assumed a brisk air—"that I could go through your parlors again before every trace of the crime perpetrated there has been removed."

"Why, you can," replied Isabella.

"There is no one in them now," added Caroline, "Franklin went out just before we left."

At which I blandly rose, and following their leadership, soon found myself once again in the Van Burnam mansion.

My first glance upon re-entering the parlors was naturally directed towards the spot where the tragedy had taken place. The cabinet had been replaced and the shelves set back upon it; but the latter were empty, and neither on them nor on the adjacent mantel-piece did I see the clock. This set me thinking, and I made up my mind to have another look at that clock. By dint of judicious questions I found that it had been carried into the third room, where we soon found it lying on a shelf of the same closet where the hat had been discovered by Mr. Gryce. Franklin had put it there, fearing that the sight of it might affect Howard, and from the fact that the hands stood as I had left them, I gathered that neither he nor any of the family had discovered that it was in running condition.

Assured of this, I astonished them by requesting to have it taken down and set up on the table, which they had no sooner done than it started to tick just as it had done under my hand a few nights before.

The girls, greatly startled, surveyed each other wonderingly.

"Why, it's going!" cried Caroline.

"Who could have wound it!" marvelled Isabella.

"Hark!" I cried. The clock had begun to strike.
