Dawson laid the letter and the telegram upon his breakfast-table, and bent his head over them. In a few minutes he had weighed them up, sorted out their relative significance, and spoke. "We have here, Froissart, two distinct people. I am almost sure of that. My man of the dockyard who wants leave to bury his mother in Essex has not yet received permission from his Chief. He would not therefore be telegraphing about his train. He does not know yet whether he will be permitted to go at all. Your man is quite confident that his movements are in no way restricted. As I read between the lines I judge that my man, who knows the actual truth about the docking and sailing of the battle-cruisers, wants to reach the East Coast, whence he has means of transmitting the priceless news to Germany. Your man is of one of the Towns; he has seen the dummy cruisers ashore in the Sound; he believes them to be genuine, and he also wants to transmit the news to his paymasters in Germany, He will be an ordinary German agent. The identity of place whither both wish to go is partly a coincidence, and partly explained by its excellence as a jumping-off place for fast motor-boats, which, during these long autumn nights, could race over to and get back again between sunset and dawn. We have coast watchers always about for the very purpose of stopping such lines of communication. You shall accompany your own man, and make sure that he is allowed to get through. If he does not himself cross, arrest him as soon as his boat has gone. If he does go, watch for his return and arrest him, and his boat and all on board, the moment that they return. In any event the boat and its crew must be seized upon return to Essex. Are you quite clear about what you have to do?" "Quite," said Froissart. "The spies and their boat must be caught red-handed, but not till after the false news of the mining of the battle-cruisers has been carried to Holland. But how shall we make certain that the sleepless English Navy will not butt in and catch the boat at sea before it gets across to Holland. The Narrow Seas swarm with fast patrols."
