And then suddenly somebody laughed. The sound came from a slope of mountain behind the hotel, and through the dark Winn's quick ear caught the sound of a light rushing across the snow. Some one must be tobogganing out there, some one very young and gay and incorrigibly certain of joy. Winn hoped he should hear Peter laughing like that later on. It was such a jolly boy's laugh, low, with a mischievous chuckle in it, elated, and very disarming. He hoped the child wouldn't get hauled up for being out so late and making a noise. He smiled as he thought that the owner of the voice, even if collared, would probably be up to getting out of his trouble; and when he turned in, he was still smiling. CHAPTER XI Dr. Gurnet's house was like an eye, or a pair of super-vigilant eyes, stationed between Davos Dorf and Davos Platz. It stood, a small brown chalet, perched high above the lake. There was nothing on either side of it but the snows, the sunshine, and the sense of its vigilance; inside, from floor to ceiling, there were neat little cases with the number of the year, and in each year there was a complete, exhaustive, and entertaining history of those who wintered, unaware of its completion and entertainment, in either of the villages. No eye but his own saw these documents, but no secret policeman ever so controlled the inner workings of a culprit's mind. There was nothing in Dr. Gurnet himself that led one to believe in his piercing quality. He was a stout little man, with a high-domed, bald head, long arms, short legs, and whitish blue eyes which had the quality of taking in everything they saw without giving anything out. Sometimes they twinkled, but the twinkle was in most cases for his own consumption; he disinfected even his jokes so that they were never catching. The consulting-room contained no medical books. There were two book-shelves, on one side psychology from the physical point of view, and in the other bookcase, psychology as understood by the leading lights of the Catholic religion. Dr. Gurnet was fond of explaining to his more intelligent patients that here you had the two points of view. "Psychology is like alcohol," he observed; "you may have it with soda-water or without. Religion is the soda-water." Two tiger skins lay on the floor. Dr. Gurnet was a most excellent shot. He was too curious for fear, though he always asserted that he disliked danger, and took every precaution to avoid it, excepting, of course, giving up the thing which he had set out to do. But it was a fact that his favorites among his patients were, as a rule, those who loved danger for its own sake without curiosity and without fear. He saw at a glance that Winn belonged to this category. Names were like pocket electric lamps to Dr. Gurnet. He switched them on and off to illuminate the dark places of the earth. He held Winn's card in his hand and recalled that he had known a former colonel of his regiment.
