"In Berlin," he said, "I was supposed to be a Roumanian officer, who had hopes of changing the attitude of that country. The Kaiser wished to show me how foolish it would be for the little Balkan state to join the Allies, and for that reason, had me shown through the German naval fortifications. That information, too, I am carrying back with me." "But why didn't you tell us who you were in Bremen, sir?" "I don't know. At first I guess because I wanted to surprise you both when you did learn who I was." "But you told us not to try and learn who you were." "Well, that was for a good reason. For, if you should have sought to pry, it might have aroused suspicions and there is no telling what would have happened." "I see, sir," said Frank. "But you almost lost us when you didn't get back in time." "I know that now. I wouldn't do the same thing again." "And what are you going to do after you return to London, sir?" Frank wanted to know. Again Lord Hastings smiled. "That's hard to tell," he replied. "Still, I imagine it will not be very long before I feel a deck under my heels again." "You mean you will leave the diplomatic service again, sir?" asked Jack. "I expect to. The king promised me a new command before he despatched me to the Balkans. But I do not know how long I shall be kept waiting." "And when you get it, sir, will we go back with you?" asked Frank. "Why," was the reply, "I should have thought that by this time you would perhaps have changed your minds." "Never, sir," declared Jack, positively. "We would rather serve under you, sir." "I'll see what can be done," Lord Hastings promised. And with that the lads were forced to be content. Still, they knew well enough that Lord Hastings would do what he could to have them with him again. "The main thing now," said Lord Hastings, "is to dodge the enemy and get back to England." "With you here, sir," said Frank, "I am sure we shall get back safely." And Frank proved a good prophet. All that day they made their way slowly through the North Sea. Several times enemy ships were sighted, but, because the little motor boat lay so low in the water, the Germans did not see them. With the coming of night, however, Lord Hastings increased the speed of the little craft. He felt that they were now beyond the German mine fields and that if another vessel were encountered it probably would be British. And this proved to be the case. Along toward morning of the second day, a British cruiser bore down on them. Soon all were aboard the vessel, which, when Lord Hastings informed the commander of the nature of the papers he carried, turned about and headed for London. A day or two later, Frank and Jack again found themselves installed in the comfortable home of Lord Hastings, where they sat down to await what time might bring forth--confident, however, that it would not be long before they were upon active service under the command of their good friend, Lord Hastings.
