Before my eyes had become quite accustomed to the darkness, my cell door opened again, and our sergeant-major beckoned me to follow him.

“Take your things with you!” he said, and led the way to another cell, farther along the corridor, to separate me from Wallace.

“Come out here! I want to talk to you!” he ordered, when I had dumped down my luggage. “Who had the key?” he shot at me when I stood opposite him in the corridor.

We had expected this, and before our escape had rehearsed our answers to such questions in case one or more of us should be caught.

“Key? What key?” I asked.

“The key to the front door, of course!”

“I don’t know anything about a key.”

“How did you get out, then? How did you open the door?”

“We didn’t open the door. We found it open. It seemed too good an opportunity, so we slipped out as we were. We weren’t prepared at all! But you ought to know all this as well as I do. Haven’t you got your report from Haltern yet?”
