The torn green curtain had been laid aside and the electric lights turned on in the inside rooms. Pallid, Sir Lucien Pyne lay by the ebony chair glaring horribly upward.

Always with the keen eyes glancing this way and that, Inspector Kerry crossed the little audience room and entered the enclosure contained between the two screens. By the side of the dead man he stood, looking down silently. Then he dropped upon one knee and peered closely into the white face. He looked up.

“He has not been moved?”

“No.”

Kerry bent yet lower, staring closely at a discolored abrasion on Sir Lucien’s forehead. His glance wandered from thence to the carved ebony chair. Still kneeling, he drew from his waistcoat pocket a powerful lens contained in a washleather bag. He began to examine the back and sides of the chair. Once he laid his finger lightly on a protruding point of the carving, and then scrutinised his finger through the glass. He examined the dead man’s hands, his nails, his garments. Then he crawled about, peering closely at the carpet.

He stood up suddenly. “The doctor,” he snapped.

Inspector Whiteleaf retired, but returned immediately with the clean-shaven man to whom Monte Irvin had been talking when Kerry arrived.

“Good evening, doctor,” said Kerry. “Do I know your name? Start your notes, Coombes.”

“My name is Dr. Wilbur Weston, and I live in Albemarle Street.”

“Who called you?”
