Late at night, two powerful men meet in a secret location to discuss a long nurtured plan about to come to fruition. One is desperate to know there is nothing standing in their way - the other assures him everything is taken care of. Hours later, a high-ranking government official called Ryan Finnegan is brutally slain in the most secure building in Ireland - Leinster House, the seat of parliament. Inspector Tom Reynolds and his team are called in to uncover the truth behind the murder.

The inspector frowned and examined the earth under the trees. As he scanned the glade, his stomach lurched. One, two, three, four. Five, counting the mound of earth disturbed under the tent. Somebody had cleared the earth of its natural layer and sown their own flowers. In five places. Five graves. A young woman, Fiona Holland, has gone missing from a small Irish village. A search is mounted, but there are whispers. Fiona had a wild reputation. Was she abducted, or has she run away?

Christmas day, and DCI Tom Reynolds receives an alarming call. A mass grave has been discovered on Oileán na Caillte, the island which housed the controversial psychiatric institution St. Christina's. The hospital has been closed for decades, and onsite graves were tragically common. Reynolds thinks his adversarial boss is handing him a cold case to sideline him. But then it transpires another body has been discovered amongst the dead - one of the doctors who went missing from the hospital in mysterious circumstances 40 years ago.

Kids can be so cruel. They'll call you names. Hurt your feelings. Push you to your death. In the garden of an abandoned house, Luke Connolly lies broken, dead. The night before, he and his friends partied inside. Nobody fought, everybody else went home safely. And yet, Luke was raped and pushed to his death. His alleged attacker is now in custody. DCI Tom Reynolds is receiving the biggest promotion of his career when a colleague asks him to look at the Connolly case, believing it's not as cut and dried as local investigators have made out.

On a Dublin city street, packed with afternoon Christmas shoppers, a young woman appears, naked, traumatised and bearing burn marks. Tom Reynolds, now chief superintendent, is no longer head of the murder squad. But when it transpires the woman escaped from a house fire started deliberately and that there are more victims, including a baby, Tom is sucked in. What begins as a straightforward case of arson, soon becomes something much more sinister. The people in that house never wanted to be there in the first place. Now more of them are missing.

DI Ben Kitto needs a second chance. After 10 years working for the murder squad in London, a traumatic event has left him grief-stricken. He’s tried to resign from his job, but his boss has persuaded him to take three months to reconsider. Ben plans to work in his uncle Ray’s boatyard, on the tiny Scilly island of Bryher, where he was born, hoping to mend his shattered nerves. His plans go awry when the body of 16-year-old Laura Trescothick is found on the beach at Hell Bay. Her attacker must still be on the island because no ferries have sailed during a two-day storm.

A dark night in the isolated Scottish countryside. Nicholas Wilson, a prominent professor known for his divisive social media rants, leaves the house with his dog, as he does every night. But this time he doesn’t come back... The last thing Inspector Logan McRae wants is to take on such a high-profile case. But when a second man vanishes in similar circumstances, the media turns its merciless gaze on him and he has no choice. Then body parts start arriving in the post. Someone out there is trying to make a point and they’re making it in blood. 

When two 18-year-old girls go missing in Thailand, their families are thrust into the international spotlight: desperate, bereft and frantic with worry.

But she can't help but think of her own son, whom she hasn't seen in two years, since he left home to go travelling.

It's DS Logan McRae's first day back on the job after a year off on the sick, and it couldn't get much worse. Three-year-old David Reid's body is discovered in a ditch: strangled, mutilated and a long time dead. And he's only the first. There's a serial killer stalking the Granite City, and the local media are baying for blood. Soon the dead are piling up in the morgue almost as fast as the snow on the streets, and Logan knows time is running out. More children are going missing. More are going to die.

Late one night a man walks into the luxurious home of disgraced banker Harry McNamara and his wife, Julie. The man launches an unspeakably brutal attack on Harry as a horror-struck Julie watches, frozen by fear. Just an hour later the attacker, JP Carney, has handed himself in to the police. He confesses to beating Harry to death, but JP claims that the assault was not premeditated and that he didn't know the identity of his victim.

When a woman is beheaded in a park outside Rome and her six-year-old son goes missing, the police unit assigned to the case sees an easy solution: they arrest the woman's husband and await his confession. But the Chief of Rome's Major Crimes unit doubts things are so simple. Secretly, he lures to the case two of Italy's top analytical minds: Deputy Captain Colomba Caselli, a fierce, warrior-like detective still reeling from having survived a bloody catastrophe, and Dante Torre, a man who spent his childhood trapped inside a concrete silo.

When a girl’s body is found strangled, raped, and horrifically mutilated by a boat’s propeller, deep in the heart of the Norfolk Broads, newly arrived Detective Inspector John Tanner is asked to assist with the investigation.

But when an alibi is produced from an unexpected source, and another body appears at the base of a slipway, Tanner finds himself turning to local girl Detective Constable Jenny Evans for help.
