Their relationship overcame a shaky start--Cordelia Graves never wanted a roommate in life, she certainly didn't want one in death. After working together to solve a few murders, the two are close friends, but there's a lingering question neither of them have been able to answer: what led to Cordelia's death? </p><p>Lately things have been adding up that suggest foul play. And when Cordelia's memories of that day start to come back, the roommates can't ignore it anymore: Cordelia was murdered. Ruby and Cordelia are going to have to piece together what Cordelia's final days looked like--otherwise a killer could go free.</p>
