"I have received a written order--or rather, a written request, for it." At this both of the visitors were dumfounded. "A written order?" gasped Hammerditch. "Yes." "By mail?" "No, a young man brought it." "Ze order must be von forgery!" came from the French Canadian. "Certainly it must be a forgery," added his companion. "It is no forgery, gentlemen." The voice came from the rear doorway, and Robert confronted them. "Who are you?" demanded Hammerditch roughly. "My name is Robert Frost." "I never heard of you before." "I am a friend to Mr. Richard Marden, the nephew of Felix Amberton." "And you come for ze map?" queried Jean Le Fevre. "Yes." "It's an outrage!" burst out Hammerditch. "The map belongs to us." "No, it belongs to Mr. Wenrich." "What do you intend to do with it?" "I intend to turn it over to Mr. Amberton and Mr. Marden." "It will do them no good." "I think it will." "Amberton shall never have that timber land." "How will you stop him?" "Never mind, he shall never have it." "We haf ze other map," said Le Fevre. "There isn't any other map," put in Herman Wenrich. "Yes, there is," said Hammerditch. "Perhaps it's one you had made down to Cresson & Page," said Robert, mentioning the firm of mapmakers, to whom he had applied for a situation. Both Le Fevre and Hammerditch were amazed. "What do you know of that?" demanded the Englishman. "He haf played ze part of a spy!" hissed the French Canadian. "I have spied upon nobody. I was at Cresson & Page's place when you came there, and I couldn't help overhear what you said about the map." "Bah, he is a spy, sure enough," ejaculated Hammerditch, in disgust. "Jean, we have played into the hands of our enemies." "Zat is so, but it shall do zem no good," answered the Canadian. "We haf better git back to Timberville as soon as possible," he added, in a whisper. "I reckon you are about right," said Hammerditch. He bowed himself toward the door. "You are going?" asked Herman Wenrich. "Yes, we are going. You have played us for a pair of fools," replied the Englishman. He ran down the stairs, with Le Fevre at his heels. Soon both were outside and stalking up the street rapidly. Robert began to laugh. "They are a pair of rascals," he remarked. "I am awfully glad I outwitted them." "So am I glad," answered Herman Wenrich. "And I am glad, too," said Nettie, with a bright smile. "But if I were you I wouldn't lose any time in getting to Timberville with the map." "I will leave this afternoon," answered the boy. CHAPTER XXIX. A LUCKY CHANGE OF STATEROOMS. Robert found that the afternoon boat for Muskegon left at half past three, so there was still time left in which to get back to Mrs. Gibbs' house for a late dinner. At the boarding house he found a short note from Livingston Palmer.
