"Will you be good enough, then, to explain about last night?"

"About last night?"

"Come, be done with evasion. Yes, about last night. Alan, I know that you and Annaik were out together in the cypress avenue, and again, on the dunes, after midnight; that you were seen walking hand in hand; and that, stealthily, you entered the house together."

"Well?"

"Well! The inference is obvious. But I will let you see that I know more. Annaik went out of the house late. Old Matieu let her out. Shortly after that you went out of the château. Later, you and she came upon Judik Kerbastiou prowling about in the woods. It was more than an hour after he left you that you returned to the château. Where were you during that hour or more?"

"I know it, because...."

"What is it, Ian?"
