"Yes."

"Then you left here about a quarter to ten. And we know that Mme. Dauvray was back at the villa soon after nine. Yes-they could not have been here last night," Hanaud agreed, and sat for a moment silent. Then he turned to the head waiter.

"Have you noticed any woman with Mme. Dauvray and her companion lately?"

"No, monsieur. I do not think so."

"Think! A woman, for instance, with red hair."

Harry Wethermill started forward. Mr. Ricardo stared at Hanaud in amazement. The waiter reflected.

"No, monsieur. I have seen no woman with red hair."

"Thank you," said Hanaud, and the waiter moved away.

"A woman with red hair!" cried Wethermill. "But Helene Vauquier described her. She was sallow; her eyes, her hair, were dark."

Hanaud turned with a smile to Harry Wethermill.
