The Anglesey Murders

DI Alan Williams is called to the recovery of two bodies from the sea at Trearddur Bay, during a storm. The lifeboat crew suspect they're fishermen, washed away by a wave, but they’re wrong. Alan and his detective sergeant, Kim Davies, realise the men were beaten and tied together before they entered the water. Two miles along the headland at Porth Dafarch, a third victim is found but there are no obvious links. As the number of victims increases, a major investigation team battles to unravel a deadly puzzle.

DI Alan Williams is faced with the most brutal murder scene he's witnessed: the ritual killing of an elderly widow. Evidence at the scene indicates that the murderer is close, and the investigation runs at breakneck speed in the hunt to stop them from striking again. Meanwhile, the busy port of Holyhead is being used by unscrupulous traffickers, who are embroiled in a violent turf war. With resources stretched, DI Williams is facing a case that could break him.

The renovation of a remote farmhouse on Anglesey uncovers a chamber of horrors but the crimes are historical. DI Alec Ramsay must sift through the evidence to identify both the victims and the perpetrators, while trying to dismantle the dangerous drug gangs that plague the city.

Rachel Evans, a selfie queen and social media superstar, went to school and never came home. DI Alan Williams and his team launch a desperate investigation to find her. As the country is plunged into lockdown, the price of narcotics skyrockets, causing friction between rival dealers.

A cold case investigation into the disappearance of 13-year-olds, Christopher Deeks and Ewan Birley, who vanished in the early '90s, opens up old wounds, old lies and a botched investigation into the very heart of the church.
