Horne Fisher is the man who 'knows too much...and all the wrong things'. He and his trusty companion Harold March take on the world of crime among societies most eminent members in eight classic mysteries. Fisher has a brilliant mind and powers of deduction - but he always faces a moral dilemma.
Harold March, the rising reviewer and social critic, was walking vigorously across a great tableland of moors and commons, the horizon of which was fringed with the far–off woods of the famous estate of Torwood Park. He was a good–looking young man in tweeds, with very pale curly hair and pale clear eyes. Walking in wind and sun in the very landscape of liberty, he was still young enough to remember his politics and not merely try to forget them. For his errand at Torwood Park was a political one; it was the place of appointment named by no less a person than the Chancellor of the Exchequer, Sir Howard Horne, then introducing his so–called Socialist budget, and prepared to expound it in an interview with so promising a penman. Harold March was the sort of man who knows everything about politics, and nothing about politicians. He also knew a great deal about art, letters, philosophy, and general culture; about almost everything, indeed, except the world he was living in. Abruptly, in the middle of those sunny and windy flats, he came upon a sort of cleft almost narrow enough to be called a crack in the land. It was just large enough to be the water–course for a small stream which vanished at intervals under green tunnels of undergrowth, as if in a dwarfish forest. Indeed, he had an odd feeling as if he were a giant looking over the valley of the pygmies. When he dropped into the hollow, however, the impression was lost; the rocky banks, though hardly above the height of a cottage, hung over and had the profile of a precipice. As he began to wander down the course of the stream, in idle but romantic curiosity, and saw the water shining in short strips between the great gray boulders and bushes as soft as great green mosses, he fell into quite an opposite vein of fantasy. It was rather as if the earth had opened and swallowed him into a sort of underworld of dreams. And when he became conscious of a human figure dark against the silver stream, sitting on a large boulder and looking rather like a large bird, it was perhaps with some of the premonitions proper to a man who meets the strangest friendship of his life.
