His childhood at least had been happy, while Lady Tristram was still the bewilderingly delightful companion who had got into so much hot water and made so many people eager to get in after her. Joy lasted with her as long as health did, and her health began to fail only when her son approached fifteen. Another thing happened about then, which formed the prelude to the most vivid scene in the boy's life. Lady Tristram was not habitually a religious woman; that temper of mind was too abstract for her; she moved among emotions and images, and had small dealings with meditation or spiritual conceptions. But happening to be in a mood that laid her open to the influence, she heard in London one day a sermon preached by a young man famous at the time, a great searcher of fashionable hearts. She drove straight from the church (it was a Friday morning) to Paddington and took the first train home. Harry was there--back from school for his holiday--and she found him in the smoking-room, weighing a fish which he had caught in the pool that the Blent forms above the weir. There and then she fell on her knees on the floor and poured forth to him the story of that Odyssey of hers which had shocked London society and is touched upon in Mr Cholderton's Journal. He listened amazed, embarrassed, puzzled up to a point; a boy's normal awkwardness was raised to its highest pitch; he did not want to hear his mother call herself a wicked woman; and anyhow it was a long while ago, and he did not understand it all very well. The woman lifted her eyes and looked at him; she was caught by the luxury of confession, of humiliation, of offering her back to the whip. She told him he was not her heir--that he would not be Tristram of Blent. For a moment she laid her head on the floor at his feet. She heard no sound from him, and presently looked up at him again. His embarrassment had gone; he was standing rigidly still, his eyes gazing out toward the river, his forehead wrinkled in a frown. He was thinking. She went on kneeling there, saying no more, staring at her son. It was characteristic of her that she did not risk diminishing the effectiveness of the scene, or the tragedy of her avowal, by explaining the perverse accident owing to which her fault had entailed such an aggravation of evil. Harry learnt that later.
