The Unfinished Clue (Country House Mysteries, Bk. 3)

A houseful of people he loathes is not Sir Arthur's worst problem…

It should have been a lovely English country-house weekend. But the unfortunate guest list is enough to exasperate a saint, and the host, Sir Arthur Billingham-Smith, is an abusive wretch hated by everyone from his disinherited son to his wife's stoic would-be lover. When Sir Arthur is found stabbed to death, no one is particularly grieved—and no one has an alibi. The unhappy guests find themselves under the scrutiny of Scotland Yard's cool-headed Inspector Harding, who has solved tough cases before. But this time, the talented young inspector discovers much more than he's bargained for.
