Readers familiar with Mallory, the intriguing and original heroine of O'Connell's four previous suspense novels, will recognize familiar themes of loss and abandonment in the brilliant, enigmatic forensic psychologist Ali Cray, whose scarred face only hints at the emotional residue of a childhood trauma. Ali ties the mysterious disappearance of two young girls to the rape and murder long ago of Susan Kendall, the twin sister of a small-town New York policeman, Rouge. Realizing that the priest who was convicted of Susan Kendall's murder is probably innocent, Rouge has a personal as well as professional reason for joining Ali in tracking down Susan's killer before he completes the ritual murder of at least one of the missing girls.
