How _could_ the pencil have got back to the hotel, and into that room, unless brought by Mr. Hardcastle? The testimony of the Swiss peasant, of the two gentlemen he had seen walking together, was terribly significant now. Mr. Prattleton, who had never been brought into contact with anything like murder in his life, felt as if he were on the eve of some awful discovery. "It was so strange that people of the Hardcastles' position should be up here in one small room on the third floor of the hotel!" cried Mrs. Dundyke, mentioning the thought that had often struck her. "Mrs. Hardcastle said no other room was vacant when they came, and that may have been so; but would they not have changed afterwards?" Mr. Prattleton went downstairs. He sought an interview with the host, and gleaned what information he could, not imparting a hint of these new suspicions. Could the host inform him who Mr. Hardcastle was? The host supposed Mr. Hardcastle was--Mr. Hardcastle. Voilà tout! Although he did think that the name given in to the hotel at first was not so long as Hardcastle, but he was not quite sure; it had not been written down, only the number of the room they occupied. Monsieur and Madame had very much resented being put up on the third floor. It was the only room then vacant in all the hotel, and at first Madame said she would not take it, she would go to another hotel; but she was tired, and stopped, and the luggage, too, had been all brought in. Afterwards, when Madame was settled in it, she did not care to change. In what name were Monsieur's letters addressed--Hardcastle? Ma foi, yes, for all he knew; but Monsieur's letters stopped at the post-office, as did those of three parts of the company in the hotel, and Monsieur went for them himself. Money? Well, Monsieur did seem short of money at times; but he had plenty at others, and he had paid up liberally at last. Other gentlemen sometimes ran short, when their remittances were delayed. There was not a word in this that could tell really against Mr. Hardcastle. The host evidently spoke in all good faith; and Mr. Prattleton began to look upon Mrs. Dundyke's suspicions as the morbid fancies of a woman in trouble. He put another question to the landlord--what was his private opinion of this singular disappearance of Mr. Dundyke? The landlord shook his head; he had had but one opinion upon the point for some days past. The poor gentleman, there was not the least doubt, had in some way got into the lake and been drowned. But the notes in his pocket-book? urged the clergyman--the money that had been changed at the money-changer's? Well, the fact must be, the host supposed, that his pocket-book was left upon the grass, or had floated on the water, and some thief had come across it and appropriated the contents.
