The duel was held on the pistol practice grounds of the garrison, a smooth, grassy place, surrounded by high bushes; at the lower end there was a shed built of strong boards, in which tools and targets were stored. At daybreak Franz von Heiden and his second dismounted at the shed and fastened their horses by the bridle. They stood side by side, looking down the road, along which a carriage was coming. Captain von Frentzen, his second, and the regimental surgeon got out. Sharp polite greetings were exchanged. On the faces of the seconds there was a singular expression of uneasiness, but Frentzen looked as though he were there for some guilty purpose. The prescribed attempts at reconciliation failed. The surgeon measured off the distance. He was a long-legged man and made the fifteen paces as lengthy as possible. Just at this moment the sun came up fully. Pistols were loaded and given to Franz and Frentzen. Fifteen paces apart, the two men faced each other. One of the seconds drew out his watch, glanced at it and said, “I shall count; ready, one! then three seconds; two!—and again three seconds; then, stop! Between one and stop the gentlemen may fire.” He glanced round once more. The four officers stood motionless in the level light of the dawn. He began to count. Presently Franz von Heiden was stretched out upon the ground, his blue eyes staring up into the new day. He lay still.... When I heard that story I ceased to be a boy. My outlook on the future had been that of an irresponsible gamester, undergoing initiation into the gayest and most exciting sports. All at once my eyes were hideously opened and I looked down into the pit that the German secret service had prepared for Franz von Heiden, and knew I _was the cause of it_. It was terrible! By leaving that map where I could see it Franz von Heiden had been guilty of an unforgivable breach of trust. By his carelessness he had let someone know that the Intelligence Department of the General Staff had procured the plans of a French fortress in the Argonne. Wherefore, according to the iron law of that soulless war machine, Franz von Heiden must die. And this is the sinister way it works. Trace it. I innocently betray him to my tutor, an official of the Secret Diplomatic Service. A few days later one of the deadliest pistol shots in the German army is transferred to Franz’s regiment. A duel is forced upon him and he is shot down in cold blood.
