“You think—that?”
“I think he was here the night Prince Michael died, and again last night.”
“It was another attempt, eh?” said Battle.
“It was another attempt.”
“What has bothered me,” continued Battle, “was wondering what had become of M. Lemoine here. I’d had word from Paris that he was on his way over to work with me, and I couldn’t make out why he hadn’t turned up.”
