"That's all right, then," I said, and turned back into the inner room.

Vantine had said that he intended examining the cabinet in detail at the first opportunity; I remembered how his eyes had gleamed as he looked at it; how his hand had trembled as he caressed the arabesques. No doubt he was making that examination when he had heard a woman's cry and had gone out into the hall to see what the matter was.

Then he and the woman had entered the ante-room together; he had closed the door; and then….

Like a lightning-flash, a thought leaped into my brain—a reason—an explanation—wild, improbable, absurd, but still an explanation!

I choked back the cry which rose to my lips; I gripped my hands behind me, in a desperate attempt to hold myself in check; and, fascinated as by a deadly serpent, I stood staring at the cabinet.

For there, I felt certain, lay the clue to the mystery!

ROGERS GETS A SHOCK

Grady, Simmonds and Goldberger examined the room minutely, for they seemed to feel that the secret of the tragedy lay somewhere within its four walls; but I watched them only absently, for I had lost interest in the procedure. I was perfectly sure that they would find nothing in any way bearing upon the mystery. I heard Grady comment upon the fact that there was no door except the one opening into the ante-room, and saw them examine the window-catches.

"Nobody could raise these windows without alarming the house," Grady said, and pointed to a tiny wire running along the woodwork. "There's a burglar alarm."
