When twelve-year-old Ciaran Devine confessed to killing his foster carer it sent shock waves through the nation. He said his older brother Thomas had tried to stop him, but the killing rage had burned too brightly. Seven years later, Ciaran’s release will set a new and even more deadly chain of events in motion.
DCI Serena Flanagan, then an ambitious Detective Sergeant, took the boy’s confession after days and weeks spent earning his trust. He hasn't forgotten the kindness she showed him – in fact, she hasn’t left his thoughts in all the years he’s been locked away.
Probation officer Paula Cunningham, reluctantly tasked with helping Ciaran re-enter society, suspects there was more to this case than the police or the prosecutors uncovered. Soon she wonders if Ciaran really committed the murder at all. His confession saved his brother Thomas from a lengthier sentence, and Cunningham sees the unnatural hold Thomas has over Ciaran.
When she brings her concerns to DCI Flanagan, the years of lies begin to unravel, leading to a truth stranger than anyone could have imagined.
