“I have thought of all that. The elevator is an electric one and any person can run it by pushing the button. All you have to do then is to unpack the wireless instrument here in your room, and after you have adjusted it you can certainly arrange in some way to get it on top of the elevator car?” “Yes,” Lawrence nodded. “Now my Mr. Black, who is at the hotel, is one of the best electricians in America. He can install the instrument easily, and I will tell you how. In the other trunk I sent up is a moving-picture machine----” “Oh, I say, come now!” said Lawrence. “I suppose you are going to tell me next that you’ve got a setting hen in another trunk and that you are going to bribe Fritz and Karl with fresh eggs. And that’s no merry jest; we haven’t seen a fresh egg in Berlin in six months.” “No, Lawrence, I’m not joking. I mean exactly what I say. I have a moving-picture machine with me and lots of films, interesting ones too, and I propose to give a show right here in the Embassy. I will ask the Secretary to allow every servant in the house to come in and see it. I can keep them quiet for an hour, and during that time you can get Black, who will be acting as my helper, into the elevator shaft and run him up to the top of the penthouse. You can depend upon him to do the rest, and all you will have to do after that is to see that he gets down before I turn up the lights, when your absence might be remarked. Isn’t that simple enough?” “But how am I to get up there to send the messages when the time comes?” asked Lawrence. “I have not thought of that yet. You may not have to send any messages at all, and if you do, it will not be for some little time, so perhaps it’s just as well that you can’t get up there without my assistance.” Then with a jolly laugh, which showed that although he was pitting his strength and wits against the great General Staff, the most wonderful machine on earth, he was as light-hearted as a boy, he said: “You might, as you did on the yacht, want to see the wheels go ‘round, or else you’d be sending messages off to a lot of girls. “Now, make haste,” he directed, “send for the trunk marked ‘Black.’” With the arrival of the trunk the machine was soon adjusted, and Edestone having tested Lawrence’s knowledge, and explained to him again exactly what he was to do, gave him orally all that was necessary for him to know about the code that was to be used. A little later, when they rejoined Jones, the Acting Ambassador, he wanted to know what they had been up to. “Has Lawrence been giving you the telephone numbers of some of these prospective war brides,” he asked, “or does he want you to take tea with some Royal Princess? You know, Jack, Lawrence seems to be quite a favourite in the very smart army set. It appears that they have heard that his grandfather was the military governor of New York. That makes him eligible. And besides, he is teaching the entire royal family the latest American dances.”
