Who Killed Mr. Garland's Mistress? — Richard Forrest

Edgar Award Finalist: A woman contemplates murder when she discovers her husband's affair in this domestic thriller set off the coast of Maine.

Helen Fraser can't remember who drew the gun, but she does remember coming home hoping her husband would apologize for what he'd done the night before. She remembers that he refused, and she remembers throwing her first punch. But then, suddenly, there was a gun in her hand, and it went off. Seven shots, just like that, and her husband was dead.
 
That's the story Tavie Garland hears through her headphones as she transcribes tapes for her husband, Rob. From the first time she hears Helen's voice, she dislikes the woman, and is certain the world would be better off if she were dead. And then she hears what sounds like her Rob making a pass at Helen, and finds herself contemplating murder. But that's only the beginning. Death is coming to the foggy Maine island where the Garland family is vacationing, and Tavie will have to fight to be the one who survives.
 
Richard Forrest chronicled countless stories of betrayal, jealousy, and murder over four decades. Who Killed Mr. Garland's Mistress?, his Edgar Awardâ€"nominated debut, is breathtaking proof that he was firing on all cylinders right from the start.
