There was a host of places that well repaid their visit, museums, picture galleries, the quaint old world buildings, the great cathedral, and others equally noteworthy. It was such a relief to be among scenes of peace after the horrors and bloodshed of so many months that they enjoyed it doubly. They took their dinner at a hotel, where though the prices were high the food was surprisingly good, and toward evening returned to the home where they had been billeted. As they neared the house, they saw a man loitering near it who seemed to have no special business in the vicinity, but kept sauntering to and fro smoking a cigar. As he saw them coming, he hesitated a moment as though half inclined to turn and go in the other direction, but seemed to think better of it, giving them a quick, sharp look as he passed them. He was in civilian dress and at first they thought he was a native of the place, but his face showed that he was unmistakably an Englishman or an American, they were not sure which. “Wonder what that fellow is hanging around here for?” Tom remarked, as they went up the steps of the house. “Oh the streets are free--that is to every one but a German, and that chap isn’t that,” remarked Billy. “Perhaps it’s some lovelorn suitor of one of the girls,” suggested Frank mischievously. “I don’t like his face,” said Tom sourly. “He has a villainous look,” added Billy. “Jealous already, eh?” laughed Frank. “I surely got your goat that time. He looks all right to me. I’d better get you fellows into the house before there’s murder done.” CHAPTER XIX THE LONE STRAGGLER The Army Boys were getting ready for supper, and Frank noted with some amusement that under one pretext or another Tom and Billy took occasion to go frequently to the window and look out. “Is he there yet?” he finally asked of Tom. “Who?” asked Tom innocently. “That deadly rival of yours,” chaffed Frank. Tom flushed a little. “Quit your kidding,” he replied. “Yes, he is there. I’ve half a mind to go out and ask him why’s he hanging around.” “I guess that would be assuming a little too much,” laughed Frank; and as the summons to supper came just then the matter was dropped. “I hope you enjoyed your holiday today,” remarked Mrs. Edsall, when they were seated at the table. “Very much,” Frank answered. “Luxemburg is a charming city. We only wish we were going to be in it longer.” “It is a nice place,” said Mrs. Edsall. “But we shall be glad to leave it just the same.” “Are you going to leave it?” asked Billy in some surprise. “Yes,” replied his hostess. “We are going back to Coblenz. My father’s property was seized there by the Germans when we left, and we are anxious to go back to reclaim it, now that the city is going to be under American control.”
