"Here we are," said Lord Hastings in German. He glanced around. "Other boats tied up here. Guess we might as well do the same," he said. "We may need it. Fortunately, at my suggestion, none of the D-17's boats bear a mark of identification. Guess it won't be bothered." The three climbed up on the pier and the boat was made fast. "Which way now, sir?" asked Frank. "We'll just do a little prowling," said Lord Hastings. He turned and was about to move off when there came a gruff hail: "Who goes there?" "Friend!" replied Lord Hastings, wheeling about quickly and looking into the heavy-joweled face of a German sentinel. The German eyed the three figures keenly; then, apparently satisfied that they were all they seemed, he brought his hand up in a stiff military salute. The three passed on. "Rather lax methods here, if you ask me," said Frank, when they were out of hearing. "Oh, I don't know," said Jack. "You must remember that they feel perfectly secure. Evidently they have no idea an enemy would venture within this fortification." "Some of them have ventured within ours," returned Frank. "Just the egotism of the German, that's all," said Lord Hastings. "They all believe they can do things that no other man would even consider." "So they do," declared Frank. Jack looked at his chum in surprise. "Just what do you mean by that?" he demanded. "Oh, I was just thinking of the _Lusitania_, and a few other things." "That's different," said Jack. They continued their walk. Now they came to a brilliantly lighted street. "I didn't know this was a regular city," was Frank's comment. "Neither is it," returned Lord Hastings, "although there are some few people living here." "But look," protested Frank, pointing, "those are restaurants and cafés; and there are stores and things." "So there are," returned his commander. "Must have changed since I was here last. However, I suppose it is because the garrison has to have some form of entertainment. Guess the best thing we can do is to go in one of these cafés and look about a bit." He led the way, and just before entering the brilliantly lighted doorway, paused long enough to say in a low voice: "No hesitation now. It would prove fatal. Walk as if you owned the place--just as every German does." The boys needed no instructions along this line, and they followed Lord Hastings with heads erect, swaggering a trifle. Inside there was revelry. German officers sat about tables that lined the four walls of the room. With them, or some of them, were their wives. Apparently it was the supper hour. At a far end of the room a string orchestra furnished music and there were four singers--two men and two women--or rather one young girl, for such Frank perceived her to be after careful inspection. A courteous waiter met the three at the door as they entered, and with many bows ushered them to a table in a distant corner. They sat down and Lord Hastings gave the order for supper.
