“Well,” said Anthony, “in your place, I should have been inclined to note down that address that I showed you. It may be of no importance⁠—quite conceivably. On the other hand, it might be very important indeed.”

Lemoine looked at him for a minute or two steadily. Then, with a slight smile, he drew back the cuff of his left coat sleeve. Pencilled on the white shirt-cuff beneath were the words “Hurstmere, Langly Road, Dover.”

“I apologize,” said Anthony. “And I retire worsted.”

He joined Superintendent Battle.

“You look very pensive, Battle,” he remarked.

“I’ve got a lot to think about, Mr. Cade.”
