"Well, sir," he said, sharply, "perhaps you will be kind enough to inform me how this scarf-pin came to be on the terrace in question."

"One moment," said Ferrari, politely lifting his hand. "Will you kindly tell me who found what you have?"

Maxwell hesitated a moment, but seeing no reason why he should conceal the part Mrs. Belk had taken in the affair, spoke out boldly.

"A woman you don't know--Mrs. Belk."

"Dio!"

"Great Heavens!"

These ejaculations proceeded, the first from Ferrari, the second from Mrs. Belswin, and in hearing them Maxwell looked suspiciously from the one to the other.

"You seem surprised."

"So will you be surprised," said Mrs. Belswin, gloomily, "when you hear what the signor has to tell you."

"I am at Signor Ferrari's service."
