The crime scene at St. Marguerite's cathedral in Mew Orleans is shocking, even to seasoned detectives like Rick Bentz and Reuben Montoya. A novice nun named Sister Camille has been found dressed in a yellowed bridal gown and viciously garroted, her body covered with an alter cloth. Valerie Houston is devastated by her sister's death. For weeks, she had begged Camille to leave St. Marguerite's, where she seemed determined to live as some kind of martyr. Camille had a reputation for making many bad choices.
