A number of men carried the luckless Tommy into one of the carriages, where he was promptly attended to by a captain of the R.A.M.C., while it was decided to detail two of the men from the troop train to mount guard until the proper reliefs arrived. Meanwhile, the wounded man could be taken to the nearest station, close to which was a hospital where he could be well looked after.

By this time there was light in plenty. Terence had no idea that a train carried so many lamps.

The next task was to look for the bodies of the two miscreants. That of the first was discovered in a ditch. He had been shot through the forehead and through the body, either wound being sufficient to cause death.

The explanation was simple: one of the wounds had been caused by the bullet from the sentry's rifle. The victim in his death agonies had convulsively gripped the trigger of his automatic pistol, and thus had caused the fusillade Terence had seen and heard. When he fired, the lieutenant's bullet had also struck the fellow, but by that time he was already a corpse.

A further search revealed a considerable cavity blown into the side of the embankment. The rocks around were scorched by the heat of the explosion, which had horribly mangled the corpse of the second conspirator, although strangely enough his features were hardly injured.

A light was flashed upon his face. Terence recognized it instantly. It was that of Major von Eckenhardt, master-spy and desperate plotter.

The rascal had met with his deserts. After his escape from Edinburgh Castle he had, according to his usual practice, laid low for a time. Then, owing to the adroit manner in which the authorities had made use of his secret wireless installation, the German Admiralty found itself landed into a very awkward situation on more than one occasion. It was not until von Eckenhardt contrived to send a secret message to his employers, explaining the reason for his failure, that the German authorities realized that they had been tricked. In reply came a message savouring of a reprimand. Von Eckenhardt ought, it said, to have taken greater precautions to prevent such eventualities. Finally the message hinted pretty broadly that an act of signal service to the Fatherland would alone atone for the blunders that the spy had made.

Von Eckenhardt was desperate. He knew that the German Secret Service had no mercy for its servants who had failed. Indeed, he wondered why he had been given another chance. By the implied tone of the communication he realized that he had to undertake a "forlorn hope." If successful, then, perhaps, he might be reinstated into favour; otherwise it would be preferable to die rather than face the penalty for failure.

Hitherto, he had been more or less a director of the spy system. With the exception, perhaps, of the part he played in attempting to wreck the "Saraband," he had kept aloof from the actual espionage work. Now, he decided he must employ his energies in a direct attack upon the resources of the British Empire.

The news of forthcoming movements on a large scale of troops from the North of England and Salisbury Plain suggested the great possibility of a striking example of German "frightfulness." He knew that the bridges and tunnels would be slenderly guarded, for the precautions adopted by the British Government at the commencement of hostilities had slackened.
