Holly Martin must find a dangerous sexual offender before he strikes again. Corporal Holly Martin's small RCMP detachment on Vancouver Island is rocked by a midnight attack on a woman camping alone at picturesque French Beach. Then Holly's constable, Chipper Knox Singh, is accused of sexually assaulting a girl during a routine traffic stop and is removed from active duty. At another beach a girl is killed. An assailant is operating unseen in these dark, forested locations. The case breaks open when a third young woman is raped in daylight and gives a precise description of the assailant. Public outrage and harsh criticism of local law enforcement augment tensions in the frightened community, but as a mere corporal, Holly is kept on the periphery. She must assemble her own clues.
