Those we left behind - Stuart Neville

When 12-year-old Ciaran Devine confessed to murdering his foster father it sent shock waves through the nation.

DCI Serena Flanagan, then an ambitious Detective Sergeant, took Ciaran's confession after days spent earning his trust. He hasn't forgotten the kindness she showed him - in fact, she hasn't left his thoughts in the seven years he's been locked away.

Probation officer Paula Cunningham, now tasked with helping Ciaran re-enter society, suspects there was more to this case than the police uncovered. Ciaran's confession saved his brother Thomas from a far lengthier sentence, and Cunningham can see the unnatural hold Thomas still has over his vulnerable younger brother.

When she brings her fears to DCI Flanagan, the years of lies begin to unravel, setting
a deadly chain of events in motion.
