“How long did you say those lorries were away unloading?”

“About four hours.”

“That would have given them time to unload in Bordeaux?”

“Yes; an hour and a half, the same out, and an hour in the city. Yes, that part of it is evidently right enough.”

Again silence reigned, and again Merriman broke it with a question.

“You have no theory yourself?”

“Absolutely none.”

“Do you think that driver mightn’t have some private game of his own on—be somehow doing the syndicate?”

“What about your own argument?” answered Hilliard. “Is it likely Miss Coburn would join the driver in anything shady? Remember, your impression was that she knew.”

Merriman nodded.
