We have no common villainy to deal with here; genius has been at work. Now sometimes an absolutely uninitiated mind will intuitively catch at something which the most highly trained intellect will miss. If such a thing should occur, remember that I am your man. Don't go round talking, but come to me. For this is going to be a great case, mind you, a great case. Now, come on."

"But the ladies?"

"They are in the rooms above; in grief, of course, but tolerably composed for all that, I hear." And advancing to a door, he pushed it open and beckoned me in.

All was dark for a moment, but presently, my eyes becoming accustomed to the place, I saw that we were in the library.

"It was here he was found," said he; "in this room and upon this very spot." And advancing, he laid his hand on the end of a large baize-covered table that, together with its attendant chairs, occupied the centre of the room. "You see for yourself that it is directly opposite this door," and, crossing the floor, he paused in front of the threshold of a narrow passageway, opening into a room beyond. "As the murdered man was discovered sitting in this chair, and consequently with his back towards the passageway, the assassin must have advanced through the doorway to deliver his shot, pausing, let us say, about here." And Mr. Gryce planted his feet firmly upon a certain spot in the carpet, about a foot from the threshold before mentioned.

"But--" I hastened to interpose.

"There is no room for 'but,'" he cried. "We have studied the situation." And without deigning to dilate upon the subject, he turned immediately about and, stepping swiftly before me, led the way into the passage named. "Wine closet, clothes closet, washing apparatus, towel-rack," he explained, waving his hand from side to side as we hurried through, finishing with "Mr. Leavenworth's private apartment," as that room of comfortable aspect opened upon us.

Mr. Leavenworth's private apartment! It was here then that _it_ ought to be, the horrible, blood-curdling _it_ that yesterday was a living, breathing man. Advancing to the bed that was hung with heavy curtains, I raised my hand to put them back, when Mr. Gryce, drawing them from my clasp, disclosed lying upon the pillow a cold, calm face looking so natural I involuntarily started.

"His death was too sudden to distort the features," he remarked, turning the head to one side in a way to make visible a ghastly wound in the back of the cranium. "Such a hole as that sends a man out of the world without much notice. The surgeon will convince you it could never have been inflicted by himself. It is a case of deliberate murder."

Horrified, I drew hastily back, when my glance fell upon a door situated directly opposite me in the side of the wall towards the hall. It appeared to be the only outlet from the room, with the exception of the passage through which we had entered, and I could not help wondering if it was through this door the assassin had entered on his roundabout course to the library.
