The Killer Inside

Forensic psychologist Megan Rhys leads another investigation in this fourth installment of the series, this time into the unusually high suicide rate among prisoners at the grim Victorian Balsall Gate jail in Birmingham. While she is there yet another death occurs, and although the police are uninterested—to them this is just another drug overdose—Megan is not convinced. Carl Kelly died in agony from something even more lethal than heroin, telling his cellmate he was being haunted by the ghost of a man he'd stabbed to death. But if Megan's instinct is right and Kelly was murdered, who is the killer?
