Raised To Kill

The initial crimes had been committed throughout the preceding decades, behind the walls of the now fire-gutted Gladstone House, which had originally been a Victorian lunatic asylum and then an orphanage, before being closed down following a headline-making exposé of gross sexual abuse by staff against many of the boys in their charge. The current spate of murder victims were ex-employees of the orphanage, and it falls to DI Matt Barnes and his team to somehow identify and apprehend a killer that they believe has harboured a need to exact vengeance for many years. But all is not what it appears to be, and their prime suspect has cast-iron alibis that seemingly cannot be broken.
