"Murder committed from any other motive than that of robbery," the Old Man in the Corner went on after a moment's pause, "always excites the interest of the public. There is nearly always an element of mystery about it, and it invariably suggests possibilities of romance. In this case, of course, there was no question of robbery. After Colonel Forburg fell, shot, as it transpired, at close range and full in the breast, his clothes were left untouched; there was loose silver in his trousers pocket, a few treasury notes in his letter-case, and he was wearing a gold watch and chain and a fine pearl stud. "The motive of the crime was therefore enmity or revenge, and here the police were at once confronted with a great difficulty. Not, mind you, the difficulty of finding a man who hated the Colonel sufficiently to kill him, but that of choosing among his many enemies one who was most likely to have committed such a terrible crime. He was the best-hated man in the county. Known as 'Remount Forburg,' he was generally supposed to have made his fortune in some shady transactions connected with the Remount Department of the War Office during the Boer War, more than twenty years ago. "His first wife was said to have died of a broken heart, and he had no children of his own; some ten years ago he had married a widow with two young children. She had a considerable fortune of her own, and when she died she left it in trust for her children, but she directed that her husband should be the sole guardian of Monica and Gerald until they came of age; moreover, she left him the interest of the whole of the capital amount for so long as they were in his house and unmarried. After his death the money would revert unconditionally to them. "Of course it was a foolish, one might say a criminal will, and one obviously made under the influence of her husband. One can only suppose that the poor woman had died without knowing anything of 'Remount Forburg's' character. Since her death his violent temper and insufferable arrogance had alienated from the children every friend they ever had. Only some chance acquaintances ever came anywhere near Brudenell Court now. Naturally every one said that the Colonel's behaviour was part of a scheme for keeping suitors away from his stepdaughter Monica, who was a very beautiful girl; as for Gerald Glenluce, Monica's younger brother, he had been sadly disfigured when he was a schoolboy through a fall against a sharp object that had broken his nose and somewhat mysteriously deprived him of the sight of one eye.
