Turning to the woman, I asked: “It’s about two and a half hours to Klein Recken, isn’t it?”

“About that.”

“Do you think you can manage that, Muller?” I looked seriously at Wallace, who understood and answered, equally serious:

“No; I’m afraid it would be too much for me.”

“Well, then, we had better go back to Haltern and on to Cologne from there. Let me see what train we can catch.” Luckily we had kept our time-table. It came in handy now.

“There’s a train at eleven-fifty-four to Cologne. We might catch that, don’t you think?”

“Anything you like, Erhardt.”

“Right-o.” To the woman: “How long do you reckon to the station in Haltern from here?”

“You can do it in a little over three quarters of an hour.”
