From which I gathered that he had heard of it, and also that he had already drawn his own inference as to the contents of the leather box.

"I 'll wait till after the inquest, Swift," he informed me at parting, with a very direct and authoritative manner; "but if this case turns up any promising features, I 'm in; get that?"

I grinned cheerfully. "Very well, Doc."

And the last I saw of him, as he went away, he was still feeling aimlessly for the silken cord, the while his mind was intent upon something else. A queer, congenial chap was Wentworth De Breen, and as keen and fine-strung, despite his absent-mindedness, as is said to be the bridge leading across to Mahomet's paradise. He had a whim for dabbling in such puzzles as my calling now and then brought me face to face with; and before I got through with Mr. Page and his ruby, this hobby of the doctor's was to supply me with an invaluable bit of evidence.

I carried the removal permit to Mr. Ulysses White, and then betook myself to a more thorough examination of the tragedy's surroundings.

First of all, I went again to the untidy bedroom and the closet above the concealed safe.

A careful and methodical search brought very little to light which I thought might subsequently be of use to me. I examined the safe carefully with an idea of discovering a secret compartment; but there was none. The position of the safe itself, evidently, had been considered sufficiently private by the builders.

I paused for a moment beside an old-fashioned walnut table which stood close by the bed's head. Its top had been covered at some remote period with artificial leather, which was held around the edges by a strip or braid of similar material, the whole made secure by ornamental brass-headed tacks placed at intervals of two or three inches.

In the dust on the imitation leather cover was an oblong imprint which, the instant I perceived it, I was seized with a caprice to measure. Its dimensions proved to be just four by three and one-half inches.

Now, this mark in the dust was so manifestly fresh, and its size and shape so suggestive, that before I was well aware of the mental operation, my mind had already accounted for its presence there.
