House of Homicide, by Eileen Magill
A young widow...
Cindy is reeling from the loss of her husband, suddenly a single mother of two children and the sole caretaker for her aging aunt. She finds the perfect house to start anew.
Cindy's dreams are invaded by a woman who shows Cindy the horrible murders that had taken place in the house. Her message to Cindy: Your family is next. When repairs on the house uncover the missing murder weapon, Cindy begins to believe that the strange woman is something more than just a dream. Using her journalism skills to research the property, the dark past of the house is revealed: a series of murders starting when the house was built more than 40 years earlier. But her meddling into the history awakens a killer's need to keep the past quiet, and Cindy is thrust into a struggle to find the killer before she and her family become the next victims.
