“Oh, there are a few things I haven't told you yet. Sit down and I'll just go over them. I've been on this case a little longer than you have, and I've done some elimination which you haven't had a chance to do.”

“And you have eliminated all but—”

“Captain Poland and LeGrand Blossom.”

At these words Jack started, and made a motion of silence. They were still in the library, but more lights had been turned on, and the place was brilliant.

“What's the matter?” asked the colonel, quickly. “I thought I heard a noise in the hall,” and Jack stepped to the door and looked out. But either he did not see, or did not want to see, a shrinking figure which quickly crouched down behind a chair not far from the portal.

“Guess I was mistaken,” said Jack. “Anyhow I didn't see anything.” Did he forget that coming out of a light room into a dim hall was not conducive to good seeing? Jack Young ought to have remembered that.

“One of the servants, likely, passing by,” suggested the colonel. “Yes, Jack, I think we must pin it down to either the captain or Blossom.”

“Do you really think Blossom could have done it?”

“He could, of course. The main question is, did he have an object in getting Mr. Carwell out of the way?”
