“I’m not sleepy.” He closed the book with a finger inserted at his page. “Are you going to Europe?”

“You know damn well I’m not.” I sat down. “We can discuss that at some future date when I’m out of the Army. It’s a relief to find you all alive and well around here. It’s very interesting down in Washington. Everybody on their toes.”
