The lads had passed the long five days in various ways. They had received the thanks of the Czar for the part they had played in exposing Count Blowinski and His Majesty had commissioned them honorary lieutenants in the Russian army. Of days they had strolled about the city taking in the sights of interest; of nights they had taken in the theaters--for there was still amusement to be found in Petrograd--a few of the most popular restaurants and other places where crowds congregated. As the two lads walked along the street this particular evening they were discussing the D-17 and the fact that they were soon to put to sea again. "I'll be glad to get back in British waters again," said Jack. "So will I," agreed Frank, "but there is no sign that when we leave here we shall go straight home." "Where else would we go?" "I don't know. But you must remember Lord Hastings has begun to keep his plans more to himself than he used to do. In fact, he told us so. We are just as likely to head for the Dardanelles or South Africa, for all we know." "Well, that's so, too," said Jack. "However, I have one of those things you call--that you call--By Jove! I can't think of the word. Premonitions, I mean." "The word you want," said Frank, "is hunch." "That's it," cried Jack. "A hunch. I have a hunch that it will not be long before we are back in England." "Well, I won't object to that." "I will be glad," said Jack, "when the time comes when we can go ashore and stay--when the war will be a thing of the past." "I am afraid that is a long ways off." "It does seem so. And still when peace does come, it probably will come suddenly." At this point in the conversation Frank looked at his watch. "Seven o'clock," he said, "and I am getting hungry. Suppose we stop in the restaurant for supper. Lord Hastings will not expect us back very early." "Suits me," said Jack. Frank led the way and a few minutes later the two lads were seated in a cozy corner of the restaurant, gazing upon the crowd that thronged the place. "This," said Frank, "reminds me of a night in Heligoland." "So it does," said Jack, and added slyly: "Except that there is a certain fair singer missing." "I had noticed that difference," said Frank. "I wonder what happened to her? I hope she did not get into trouble." "I think she is smart enough to look out for herself," said Jack. "Some of these days, when the war is over, we may possibly encounter her some place." "I wish we would. We owe her a whole lot." "So we do," agreed Jack. "Now if she----" The lad broke off suddenly and laid a hand on his chum's arm. "What's the matter?" demanded Frank. For answer Jack pointed cautiously to a form at the far end of the room. The man's back was turned and he had not seen the lads. "Well?" said Frank inquiringly, after glancing at the man. "Doesn't he look familiar to you?" asked Jack. "No; I can't say that he does--not from the back, at any rate. Whom do you think he is?"
