It may be Christmas in New York, but for ex-soldier turned élite bodyguard Ryan Lock it's business as usual: his mission is to protect one of America's most ruthless businessmen. Suddenly gunshots ring out. People run for cover. Innocent people are mown down. Amid the chaos, Lock's hunt for the killers turns into an explosive game of cat and mouse.

It begins with a letter... The letter contains a request - think of a number, any number - and a sealed envelope. Inside the envelope is that number... When Dave Gurney, retired NYPD homicide detective, is contacted by an old college acquaintance about some startling letters he’s been receiving, it is at first little more than a diverting but sinister puzzle. Until the acquaintance is brutally killed.Suddenly Gurney finds himself in the middle of a murder investigation that makes no sense.

Detective Miles Jensen is called to the lawless town of Santa Mondega to investigate a spate of murders. This would all be quite ordinary in those rough streets, except that Jensen is the Chief Detective of Supernatural Investigations. The breakneck plot centres around a mysterious blue stone, 'The Eye of the Moon', and the men (and women) who all want to get their hands on it: a mass murderer with a drink problem, a hit man who thinks he's Elvis and a pair of monks among them.

First, Patrick receives a DVD in the post. It shows footage of him and his wife Ariana walking, dressing, going to work - all filmed by cameras hidden in their house. Someone is clearly out to get him. And then the email arrives: GO ALONE. TELL NO ONE. DO WHAT WE SAY. OR SHE DIES. Patrick’s life is turned upside down. Suddenly this has become a matter of life and death.

Daniel Brasher left a high-paying job as a money manager to work at a job he loves, leading counselling sessions with recently paroled ex-cons. Now he's ready to move on and start a private practice. But before he leaves, he finds an envelope in his mailbox - one intended for someone else. Inside is an unsigned note that says: "admit what you've done or you will bleed for it. you have 'til november 15 at midnite." The deadline has already passed and the person to whom the envelope was addressed was brutally murdered. Is Daniel next?

Jack Reacher jumps off a bus and walks 14 miles down a country road into Margrave, Georgia. An arbitrary decision he's about to regret. Reacher is the only stranger in town on the day they have had their first homicide in 30 years. The cops arrest Reacher and the police chief turns eyewitness to place him at the scene. As nasty secrets leak out and the body count mounts, one thing is for sure.

Nick Horrigan has finally put his traumatic past behind him...until a SWAT team smashes into his place in the middle of the night. He's told that a terrorist has seized control of a nuclear power plant and is threatening to blow it up... Unless he can talk to Nick. As Nick rockets toward the truth, peeling back layer after layer of lies and deception, only one thing is certain: the long-buried secret, tied to the traumas of his own past, threatens his life at every turn.

Do you need my help? It was always the first question he asked. They called him when they had nowhere else to turn. Raised and trained as part of a top-secret programme, he was sent to the worst places in the world to do things his government denied any knowledge of. Then he broke with the programme and disappeared. But now someone's on his tail. Someone who knows he was once known simply as Orphan X.

Nine hundred and seventy-three days. Thinking. Planning. Waiting for the perfect moment. Former Marine James Bishop will only have one opportunity to make his prison break. And one chance to prove that he isn't responsible for the murders that put him inside. Three years ago Bishop was the leader of an elite close protection team hired to protect a millionaire and his daughter.

Ryan Drake is a man who finds people who don't want to be found. Once a British soldier, he now works for the CIA, leading an elite investigation team that tracks down missing agents. But his latest mission - to free a prisoner, code-named Maras, and bring her back onto US soil within 48 hours - is more dangerous than anything his team has attempted before. Hunted by his former comrades, Drake is left with no choice but to trust a dangerous woman he barely knows.

Jacob Reese enjoys the quiet life, running a coffee shop and renting out his cottage in The Hollows, Vermont. But the calm is shattered when a woman who looks eerily similar to his ex-girlfriend Laura turns up to stay in the cottage, and leaves a mysterious note in the guest book. Now Jacob’s seeing Laura everywhere - a glimpse of her face across the street, her music box left outside his house, a gift he gave her years before hanging from the trees. But it can’t be Laura. Because Laura’s dead.

Deep in the wilds of Siberia, a woman is on the run, pursued by a man harbouring secrets - a man intent on killing her. Half a world away, James Reece is recovering from brain surgery in the Montana wilderness, slowly putting his life back together with the help of investigative journalist Katie Buranek and his longtime friend and SEAL teammate Raife Hastings.

Detective Chief Inspector Harry Grimm is forced to take leave from Bristol’s Major Investigations Team when his boss, tired of Harry chasing the ghost of his murderous father, sends him north on secondment. Used to city life and high stress, Harry fears his life will now be spent handing out speeding tickets, finding lost sheep, and directing tourists. But when a local teenager runs away, Harry finds himself pulled into an investigation much worse than anyone could have ever expected. 

‘I know you, don’t I?’ Five words - that’s all it takes to plunge Mike Wingate and his family into mortal danger. Mike doesn’t recognise the crippled stranger who approaches him at a party... but the stranger seems to know all about him. What has Mike done? Do they have the wrong man? Overnight, the threats become attacks, and Mike, his wife, and their young daughter learn they aren’t safe anywhere - especially not their own home. He doesn’t know who they are. He doesn’t know what they want.

When Cal Weaver stops at a red light on a rainy night while driving home, he ignores the bedraggled-looking teenaged girl trying to hitch a lift. Even when she starts tapping on his window. But when she says, 'hey, aren't you Scott's dad?' and he realizes she's one of his son's classmates, he can't really ignore her. OK, so giving a ride to a teenage girl might not be the smartest move, but how much harm could it do? Over the next 24 hours Cal is about to find out.
