Muchmore, it appeared, had always been a bad character, but he had told his uncle that he had reformed, and had begged his relative to give him a home. No sooner was he installed in the mansion than he began to scheme to get possession of it, and also what other property Mr. Stockton had. To this end he secretly administered to his aged relative a medicine which greatly weakened him. Then, when the old man was not capable of defending himself, Muchmore had shut him up in an unused part of the house. From then on the nephew's course became bolder. He began his wild, gambling life, introducing some of his cronies into the mansion. He compelled Mrs. Blarcum to do as he wished by telling her Mr. Stockton was crazy, and had to be kept a prisoner. Muchmore's strange actions, when the young firemen were first at the house, was due to his fear lest they discover that Mr. Stockton was a prisoner in his own mansion. Then Muchmore began to make out deeds and other papers, compelling his uncle, by threats of violence, to sign such as were necessary for his purpose. Mr. Stockton tried several times to escape, but the rascally nephew and housekeeper were too much for him. Once Mr. Stockton managed to get as far as the office where Mort Decker, under the direction of Muchmore, was in the habit of copying deeds. The stenographer was out at the time, and the office was deserted, and, as he could not find a pen, the old man used the typewriter to prepare the mysterious note Herbert found. He was disturbed before he could finish it, but he carried it away with him, and, at the first opportunity, threw it from the window. But now he had no more to fear, thanks to the rescue by Herbert. "I can't thank you enough," he said to the young chief. "But for you I might still be a prisoner." "You helped yourself as much as we helped you," said Bert "It was a good idea, to think of starting that fire." "Yes, it was the only thing I could think of. This place is so lonesome that persons seldom pass by, or I might have called to some of them, when I was well enough. Often I had to stay in bed for days at a time. I made the fire of some old papers and rags, and I had a pail of water ready to throw on it in case it got going too fiercely. Then Muchmore came and caught me, and locked me up. Oh, how I prayed that they might send in an alarm, and that the fire department would come, for I heard from the old housekeeper that a company had been started in addition to the old hand-engine corps." "Yes, we think we have quite a fine department," said Herbert proudly. "Well, you'll soon have a better one," said Mr. Stockton. "I want to show my appreciation in some way, and I'm going to buy a regular steam-engine for the town." "But we'll need a water system for that," objected Bert.
