Suddenly a word of command caused them to halt against a wall, and a sergeant, stepping forward, took a handkerchief and tied it over the eyes of the quivering culprit, who now stood with his back against the wall. Another word from the officer, and the party receded some distance, leaving the man alone. The monotonous nasal utterances of the chaplain still sounded as four privates advanced, and, halting, stood in single rank before the prisoner. [Illustration: EXECUTION OF VON BEILSTEIN ON THE HORSE GUARDS' PARADE.] They raised their rifles. There was a momentary pause. In the distance a dog howled dismally. A sharp word of command broke the quiet. Then, a second later, as four rifles rang out simultaneously, the condemned man tottered forward and fell heavily on the gravel, shot through the heart. It was the spy and murderer, Karl von Beilstein! He had been brought from Glasgow to London in order that certain information might be elicited from him, and after his actions had been thoroughly investigated by a military court, he had been sentenced to death. The whole of his past was revealed by his valet Grevel, and it was proved that, in addition to bringing the great disaster upon England, he had also betrayed the country whose roubles purchased his cunningly-obtained secrets. Geoffrey Engleheart, although gallantly assisting in the fight outside Leatherhead, and subsequently showing conspicuous bravery during the Battle of Caterham, fortunately escaped with nothing more severe than a bullet wound in the arm. During the searching private inquiry held at the Foreign Office after peace was restored, he explained the whole of the circumstances, and was severely reprimanded for his indiscretion; but as no suspicion of von Beilstein's real motive had been aroused prior to the Declaration of War, and as it was proved that Geoffrey was entirely innocent of any complicity in the affair, he was, at the urgent request of Lord Stanbury, allowed to resume his duties. Shortly afterwards he was married to Violet Vayne, and Sir Joseph, having recovered those of his ships that had been seized by the Russian Government, was thereby enabled to give his daughter a handsome dowry.
