Detective Sergeant Cormac Reilly has moved with his girlfriend to a new town and is once again a newbie in the ranks of the local police branch. Tasked to cast a fresh eye over their cold cases, Cormac is diligently ploughing through the work but is keen to take on something more high profile. It does niggle that he is not tackling anything current and that his new Galway colleagues aren’t that welcoming, but there is at least one friendly face in the office and Cormac knows he must prove his worth once again to a new audience.
When presented with a case file from twenty years ago, Cormac is shocked to realize that as a young and fresh police officer, he was the Garda involved in the original callout. Five year old Jack Blake was placed into foster care and as for the teenage sister Maude, that was the last anyone heard of her after the death of her mother. It saddens Cormac to be told that the body recently found in the local river was that of the now twenty-five year old Jack Blake. Jack’s doctor girlfriend Aisling is in shock over her partner’s death but soon has a new ally to stir things up – the newly returned Maude.
