"You must come with me," he added; "you and your witnesses."
"Sorry I cannot," said Kenneth.
The sergeant pricked up his ears.
"I order you," he declared.
"Tell me where you are taking the prisoner, and we will be there as soon as possible. At three o'clock I have an appointment with Commandant Fleurus, and it is nearly that hour now."
The sergeant acquiesced, but took the precaution of discreetly sending a couple of men to watch the movements of the two corporals in Belgian uniform who were stated to be English. Experience had taught him that there were such things as forged documents, and that Germans had masqueraded as English officers and men.
"You are slightly after time," was Commandant Fleurus's remark as the dispatch-riders presented themselves.
"We arrested a spy, sir," announced Kenneth. "He gave himself away."
"How was that?" asked the Commandant.
Kenneth reported the details, and how Jules de la Paix had rashly declared that he was compelled to denounce the English lads to von Koenik at Brussels.
