When her friend apparently commits suicide, California probation officer Carolyn Sullivan refuses to believe the woman would have taken her own life. But in trying to prove the victim was murdered, Sullivan has very little in the way of evidence until somebody sends her a note demanding that she drop the Campbell case. Digging deep into her late friend's life, she discovers myriad secrets and pinpoints a murder suspect. The trick will be bringing the killer to justice while remaining in one piece.--From Booklist.
