Just Take My Heart by Mary Higgins Clark
After famous actress Natalie Raines is found in her home, dying from a gunshot wound, police immediately suspect her theatrical agent and jealous soon-to-be-ex-husband, Gregg Aldrich. But no charges are brought against him until two years later, when a career criminal suddenly claims Aldrich had tried to hire him to kill her.
The case is a plum assignment for attractive thirty-two-year-old assistant prosecutor Emily Wallace. She spends long hours preparing for the trial, and unaware of a seemingly well-meaning neighbor's violent past, gives him a key to her home to care for her dog.
The high-profile trial makes headlines, threatening to reveal personal matters about Emily, such as the fact that she had a heart transplant-- especially when she experiences eerie sentiments that defy all reason and continue even after the jury decides Gregg Aldrich's fate.
But little does she know, now her own life is at risk.
