Ellery shrugged again. He opened his bag with pointed nonchalance. There, plainly revealed on his haberdashery, lay the.38 police revolver. He tossed it aside.

“Do you always carry a gun, Mr. Queen?” murmured Dr. Reinach.

“Always.” Ellery picked up the revolver and slipped it into his hip pocket.

“Charming!” The fat man stroked his triple chin. “Charming. Well, Mr. Queen, if you’ll excuse me I’ll see how Thorne is getting on. Stubborn fellow, Thorne. He could have taken pot luck with us this past week, but he insisted on isolating himself in that filthy den next door.”

“I wonder,” murmured Ellery, “why.”

Dr. Reinach eyed him. Then he said: “Come downstairs when you’re ready. Mrs. Reinach has an excellent dinner prepared and if you’re as hungry as I am, you’ll appreciate it.” Still smiling, the fat man vanished.

Ellery stood still for a moment, listening. He heard the fat man pause at the end of the corridor; a moment later the heavy tread was audible again, this time descending the stairs. Ellery went swiftly to the door on tiptoe. He had noticed that the instant he had come into the room.

There was no lock. Where a lock had been there was a splintery hole, and the splinters had a newish look about them. Frowning, he placed a rickety chair against the door-knob and began to prowl.

He raised the mattress from the heavy wooden bedstead and poked beneath it, searching for he knew not what. He opened closets and drawers; he felt the worn carpet for wires. But after ten minutes, angry with himself, he gave up and went to the window. The prospect was so dismal that he scowled in sheer misery. Just brown stripped woods and (lie leaden sky; the old mansion picturesquely known as the Black House was on the other side, invisible from this window.

A veiled sun was setting; a bank of storm clouds slipped aside for an instant and the brilliant rim of the sun shone directly into his eyes, making him see colored, dancing balls. Then other clouds, fat with snow, moved up and the sun slipped below the horizon. The room darkened rapidly.
