Paget, attired in evening clothes, came upstairs with him.

“Good evening, doctor,” Paget said lazily. “Anything of interest to me?”

“Nothing.”

Paget dropped into a chair and gazed carelessly at Willis. The physician sat beside Paget and also watched the secretary as he worked.

Once again Doctor Lukens obeyed the impulse to turn toward Paget. He discovered the visitor looking at the scarab ring on his left hand.

Paget smiled sheepishly.

“Curious ring, doctor,” he said, indicating the object with his hand. “I do not recall seeing you wear it before.”

“It belonged to Henry Marchand,” replied the physician. “He presented it to me some time ago. I came across it to-day in my home.”

The physician had scarcely completed his statement before a suspicion seized him.

Why had Paget noticed the ring? The clubman was not usually observant. At that instant Doctor Lukens suddenly realized that Paget, when he had visited the house in the morning, had been staring at the scarab ring — not at the papers which Lukens had held.
