Miss Silver Comes to Stay - Patricia Wentworth

When he was 21 James Lessiter told Henrietta Cray that he loved her before all things and so broke Catherine Lee’s heart. But James has a side to him that most people do not see. When the engagement is broken off noone is sure why and Rietta refuses to explain. Twenty years later James returns to the village an extremely wealthy man. Rietta is still unmarried and Catherine is a penniless widow living in a cottage on the Lessiter estate. Trouble is inevitable, for Catherine has started to sell some of the valuable contents of the cottage to keep up a lifestyle she cannot afford but James has his suspicions and is looking forward to exposing her. He has always enjoyed seeing someone else suffer whatever the cost. When he is brutally murdered there all too many people who would benefit from his death but fortunately Miss Silver is ready to investigate.
