Naked cruelty - Colleen McCullough

Locking your door won't help. He's already inside.

America in 1968 is in turmoil and the leafy Holloman suburb of Carew is being silently terrorised by a series of vicious and systematic rapes. When finally one victim finds the courage to speak out and go to the police, the rapist escalates to murder.

For Captain Carmine Delmonico, it seems to be a case with no clues. And it comes as the Holloman Police Department is troubled: a lieutenant is out of his depth, a sergeant is out of control, and into this mix comes the beautiful, ruthlessly ambitious new trainee, Helen MacIntosh, daughter of the influential president of Chubb University.

As the killer makes his plans, Carmine and his team must use every resource at their disposal - including a highly motivated neighbourhood watch, the Gentlemen Walkers.
