If Sir Horace had gone to bed before the murderer entered the house it would have been natural to expect no lights turned on. But he had returned unexpectedly; there were no servants in the house, and there was no bed ready for him. In any case, if he intended stopping in the empty house instead of going to a hotel he would have been wearing a sleeping suit when his body was discovered; or, at most, he would be only partially dressed if he had got up on hearing somebody moving about the house. But the body was fully dressed, even to collar and tie. It was absurd to suppose that the victim had been sitting in the darkness when the murderer appeared. Another difficult problem Scotland Yard had to face was the discovery of the person who had sent them the news of the murder. How had Scotland Yard's anonymous correspondent learned about the murder, and what were his motives in informing the police in the way he had done? Was he connected with the crime? Had the murderer a companion with him when he broke into Riversbrook for the purpose of burglary? That seemed to be the most probable explanation. The second man had been horrified at the murder, and desired to disassociate himself from it so that he might escape the gallows. The only alternative was to suppose that the murderer had confessed his crime to some one, and that his confidant had lost no time in informing the police of the tragedy. The newspaper accounts of the case threw some light on the private and domestic affairs of the victim. He was a widower with a grown-up daughter; his wife, a daughter of the late Sir James Goldsworthy, who changed his ancient family patronymic from Granville to Goldsworthy on inheriting the great fortune of an American kinsman, had died eight years before. Sir Horace's Hampstead household consisted of a housekeeper, butler, chauffeur, cook, housemaid, kitchenmaid and gardener. With the exception of the butler the servants had been sent the previous week to Sir Horace's country house in Dellmere, Sussex. It appeared that Miss Fewbanks spent most of her time at the country house and came up to London but rarely. She was at Dellmere when the murder was committed, and had been under the impression that her father was in Scotland. According to a report received from the police at Dellmere the first intimation that Miss Fewbanks had received of the tragic death of her father came from them. Naturally, she was prostrated with grief at the tragedy.
