Twenty-six-year-old Maggie Barnes is someone you would never look at twice. Living alone in a month-to-month sublet in the huge city of London, with no family but an estranged sister, no boyfriend or partner, and not much in the way of friends, Maggie is just the kind of person who could vanish from the face of the earth without anyone taking notice. Or just the kind of person MI5 needs to infiltrate the establishment and thwart an international plot that puts all of Britain at risk. Now one young woman has the chance to be a hero - if she can think quickly enough to stay alive.

At MI5 headquarters Regent's Park, First Desk Claude Whelan is learning the rule (cover your arse) the hard way. Tasked with protecting a beleaguered prime minister, he's facing attack from all directions himself. Over at Slough House, the MI5 satellite office for outcast and demoted spies, the agents are struggling with personal problems: repressed grief, various addictions, retail paralysis, and the nagging suspicion that their newest colleague is a psychopath. Plus someone is trying to kill Roddy Ho.

Eben Adams is a young painter in Depression-era New York just looking to make a living. His work has thus far left influential art dealers unimpressed. Then Eben happens upon a young schoolgirl named Jennie in Central Park. Intrigued by her mystical quality and her knowledge of things that happened well before her time, Eben begins to sketch a portrait of the young girl. The drawing turns out to be the most emotional piece Eben has ever done, and he finally gets the boost in his career he's been seeking. But before he can finish the portrait, Jennie vanishes.

Dr Nell Ward is in the lush, emerald hills of Ireland, to attend the wedding of two dear friends at a picture-perfect farmhouse. But family tensions are running high in the days before the happy couple tie the knot. And when Nell sees a fox kill a hare in the early morning light, it sends shivers down her spine. Almost like it is a sign of something to come... Then one of the locals makes a gruesome discovery in a nearby peat bog. Famous for the ancient bodies these habitats preserve, what has been found instead is a woman who died much more recently...

Murder is a dish best served ice cold... In the idyllic, small town of Dewstow, Margery and Clementine are eagerly awaiting retirement from their work on the front-line serving meals to the students at Summerview secondary school. Their peaceful life is shattered when their kitchen manager is found dead in the school’s walk-in freezer. The police are adamant that it’s an open-and-shut case of accidental death. But Margery and Clementine are convinced that something more sinister is afoot and take it upon themselves to investigate.

In a peaceful retirement village, four unlikely friends meet weekly in the Jigsaw Room to discuss unsolved crimes; together, they call themselves the Thursday Murder Club. When a local developer is found dead with a mysterious photograph left next to the body, the Thursday Murder Club suddenly find themselves in the middle of their first live case.
