Suddenly he heard everything plainly, and a sentence struck him. "I hope he'll be careful," he heard someone say. "The whole lot of us would swing if we were found here together." The man spoke in German, and Dick's interest became tense.

"More likely be shot," someone retorted, with a laugh.

"But we're safe enough. This is the first time we've been here, and every care has been taken."

"I know," said someone, who appeared doubtful, "but if the British Secret Service people have been fools in the past, they are sharp enough now. Schleswig thought he was as safe as houses, but he was cleverly nabbed, and now he's cold meat."

"Never mind," said another voice, "our turn is coming. Gott in Himmel, won't we let them know when we are masters of London! Even now the English don't know that their country is a powder magazine. They little think that, in spite of their Alien Acts and the rest of it, the country is still riddled with friends of the Fatherland. Hark, he's coming!"

This was followed by a general shuffling of feet, and Dick instinctively felt that something of importance was about to happen. He wondered at the ease with which he could now hear. Evidently the partition which hid him from the room in which the conspirators had met (for evidently they were conspirators) was thin, or else there must have been some secret channel by which the sounds reached him. He realised, too, that these people had not entered by way of Chainley Alley, but that their room must have an outlet somewhere else. Possibly, probably too, as they had used this meeting-place for the first time that night, these people would be ignorant of the closet where he was hidden.

Dick heard a new voice, and he detected in a moment that it was a voice of authority. I will not attempt to relate all he heard, or attempt to give a detailed description of all that took place. I will only briefly indicate what took place.

The newcomer, who was evidently the person for whom the others had waited, seemed to regard those to whom he spoke as his subordinates. He was apparently the leader of a movement, who reported to his workers what progress had been made, and who gave them instructions as to the future.

He began by telling them that things were not going altogether well for the Fatherland, although he had no doubt of final victory.

But England—Great Britain—was their great enemy, and, unless she were conquered, Germany could never again attempt to be master of the world. But this could never be done altogether by force of arms.
