Rage and Retribution: The DI Sterling Series

Detective Inspector Paolo Sterling has more headaches than usual. Someone is abducting men and subjecting them to horrific acts of rape and torture, but who? More to the point - why? After three days of cruelty and starvation, they are released. Why will none of them give any information which would help the police to find the perpetrator? The victims refuse even to admit they were held captive.
