The course of Frank Mackey's life was set by one defining moment when he was 19. The moment his girlfriend, Rosie Daly, failed to turn up for their rendezvous in Faithful Place, failed to run away with him to London as they had planned. Frank never heard from her again. Twenty years on, Frank is still in Dublin, working as an undercover cop. He's cut all ties with his dysfunctional family. Until his sister calls to say that Rosie's suitcase has been found....

The photo shows a boy who was murdered a year ago.The caption says, "I know who killed him". Detective Stephen Moran hasn't seen Holly Mackey since she was a nine-year-old witness to the events of Faithful Place. Now she's 16 and she's shown up outside his squad room, with a photograph and a story. Even in her exclusive boarding school, in the graceful golden world that Stephen has always longed for, bad things happen and people have secrets.

Antoinette Conway, the tough, abrasive detective from The Secret Place, is still on the Murder Squad, but only just. She's partnered up with Stephen Moran now, and that's going well - but the rest of her working life isn't. Antoinette doesn't play well with others, and there's a vicious running campaign in the squad to get rid of her.

Still traumatised by her brush with a psychopath, Detective Cassie Maddox transfers out of the murder squad and starts a relationship with fellow detective Sam O'Neill. When he calls her to the scene of his new case, she is shocked to find that the murdered girl is her double. What's more, her ID shows she is Lexie Madison - the identity Cassie used years ago as an undercover detective.

When he was 12 years old, Adam Ryan went playing in the woods one day with his two best friends. He never saw them again.

Twenty years on, Rob Ryan - the child who came back - is a detective in the Dublin police force. He's changed his name. No one knows about his past.

Cal wants nothing to do with any kind of investigation, but somehow he can't make himself walk away.

In a world of lies, one truth remains. Dead men tell no tales...When the body of an unidentified man is found at the foot of Sheringham cliffs with injuries inconsistent with a fall, DI Tom Janssen must piece together his final days to determine how he fell to his death...or who pushed him...The investigation quickly reveals a network of locals with ties to the victim, but as for the man himself...he remains something of a mystery. The dead man doesn't fit in; not with his social circle, not with his business interests, and when others come looking for him, the intrigue only deepens.

When a body is discovered at a popular Highland landmark, it seems like just another day on the job for DCI Jack Logan and his team. Except this body is missing a very vital component, and given its location - The Well of Seven Heads - it seems like someone is trying to send a message. But why? And to whom? 

When a young man is found frozen to death on a Highland street in mid-December, DCI Jack Logan initially puts it down to a Christmas night out gone tragically wrong. But, when a postmortem reveals something more sinister, Jack discovers he is dealing with a cold, calculating killer with a long line of victims, a talent for torture, and a perverse sense of justice. 

A secret worth dying for is a secret worth killing...When a violent storm uncovers the remains of an unknown young woman, long buried among the sand dunes, DI Tom Janssen must piece together fragmentary evidence to determine how she came to be there. In the years she lay undiscovered, several young women have disappeared, and as the team works through the possibilities, they come to an uncomfortable conclusion...Is a serial killer stalking coastal Norfolk? Each missing person had a story. Each of them had enemies. Some were more dangerous than others...

When a body is found on a lonely cliff top path, the angelic face of a murdered teenager lies facing the rising sun. Strangled by the hands of an unknown killer, it falls to DI Tom Janssen and his fledgling team to find out how she came to be there. Destined for a career in medicine, one to rival that of her parents, Holly Bettany’s future was as bright as it had been privileged. Seemingly, all that could threaten this promising teenager’s life was Holly herself.

When the mutilated remains of a woman are retrieved by local fishermen, it falls to DI Tom Janssen and his team to identify how she came to be in the water and what put her there. Joined on the case by his new permanent boss, DCI Tamara Greave, it remains to be proven if the woman's death was a result of foul play or a tragic accident.

The charred remains of an elderly woman are discovered in a burned-out gamekeeper's cottage, hidden away in woodland to the west of Edinburgh. Clearly no accidental fire, Detective Inspector Tony McLean suspects that neither is this simply a grim arson attack. There is far more to the victim than her humble surroundings might suggest, and something ritualistic to her horrific murder. Nor will it be the only case of death by fire that Tony and his team will be faced with. This is only the beginning, and with such evil clouding the air, Tony begins to wonder what else will burn.... 

How far would you go to bury the truth? While searching for a missing hill walker, Glencoe Mountain Rescue Team uncovers a body - just not the one they were looking for. Still dealing with the fallout from their last case, DCI Jack Logan and his team venture south from Inverness to investigate a brutal, gangland-style execution in the wilds of the Highland countryside. As the victim's dark secrets are gradually revealed, Jack uncovers the rot lurking beneath the stunning scenery, making himself the target of a criminal more dangerous than any he has faced before.

Just when he thought he was out.... Burdened by guilt over the trauma recently inflicted on his friends and colleagues, former-Detective Chief Inspector Jack Logan has spent the past nine months living in self-imposed exile. When a mother and her young daughter are the victims of a double murder staged to look like suicide, Logan is dragged back to help hunt down and catch a brutal, calculating killer. But the world has moved on without him.
