DCI Serena Flanagan

When 12-year-old Ciaran Devine confessed to murdering his foster father, it sent shock waves through the nation. DCI Serena Flanagan took Ciaran's confession after days spent earning his trust. He hasn't forgotten the kindness she showed him - she hasn't left his thoughts at all. But was there more to this case than the police uncovered? When concerns are brought to DCI Flanagan, the years of lies begin to unravel, setting a deadly chain of events in motion.

Blood has always been thicker than water for two Northern Irish brothers caught in the Belfast foster system, but a debt of past violence will be paid not just by them but also by those they left behind. Ciaran Devine, who made Belfast headlines seven years ago as the "schoolboy killer", is about to walk free. At the age of 12, he confessed to the brutal murder of his foster father; his testimony mitigated the sentence of his older brother, Thomas, who was also found at the crime scene, covered in blood.
