He smiled with that extraordinary Sunday-school docility of his.

“It was very simple, Cornelis. I was foolish in the cafe—but they have told you of that. You see I was angry and did not reflect. They had separated us, and I could see would treat me as dirt. Therefore, my bad temper came out, for, as I have told you, I do not like Germans.”

Peter gazed lovingly at the little bleak farms which dotted the Hungarian plain.

“All night I lay in tronk with no food. In the morning they fed me, and took me hundreds of miles in a train to a place which I think is called Neuburg. It was a great prison, full of English officers ... I asked myself many times on the journey what was the reason of this treatment, for I could see no sense in it. If they wanted to punish me for insulting them they had the chance to send me off to the trenches. No one could have objected. If they thought me useless they could have turned me back to Holland. I could not have stopped them. But they treated me as if I were a dangerous man, whereas all their conduct hitherto had shown that they thought me a fool. I could not understand it.

“But I had not been one night in that Neuburg place before I thought of the reason. They wanted to keep me under observation as a check upon you, Cornelis. I figured it out this way. They had given you some very important work which required them to let you into some big secret. So far, good. They evidently thought much of you, even yon Stumm man, though he was as rude as a buffalo. But they did not know you fully, and they wanted to check on you. That check they found in Peter Pienaar. Peter was a fool, and if there was anything to blab, sooner or later Peter would blab it. Then they would stretch out a long arm and nip you short, wherever you were. Therefore they must keep old Peter under their eye.”

“That sounds likely enough,” I said.

“It was God’s truth,” said Peter. “And when it was all clear to me I settled that I must escape. Partly because I am a free man and do not like to be in prison, but mostly because I was not sure of myself. Some day my temper would go again, and I might say foolish things for which Cornelis would suffer. So it was very certain that I must escape.

“Now, Cornelis, I noticed pretty soon that there were two kinds among the prisoners. There were the real prisoners, mostly English and French, and there were humbugs. The humbugs were treated, apparently, like the others, but not really, as I soon perceived. There was one man who passed as an English officer, another as a French Canadian, and the others called themselves Russians. None of the honest men suspected them, but they were there as spies to hatch plots for escape and get the poor devils caught in the act, and to worm out confidences which might be of value. That is the German notion of good business. I am not a British soldier to think all men are gentlemen. I know that amongst men there are desperate skellums, so I soon picked up this game. It made me very angry, but it was a good thing for my plan. I made my resolution to escape the day I arrived at Neuburg, and on Christmas Day I had a plan made.”

“Peter, you’re an old marvel. Do you mean to say you were quite certain of getting away whenever you wanted?”

“Quite certain, Cornelis. You see, I have been wicked in my time and know something about the inside of prisons. You may build them like great castles, or they may be like a backveld tronk, only mud and corrugated iron, but there is always a key and a man who keeps it, and that man can be bested. I knew I could get away, but I did not think it would be so easy. That was due to the bogus prisoners, my friends, the spies.
