The last thing Liz, Thelma and Pat imagined was that they would become involved in a murder. But they know there’s more to Topsy’s death than meets the eye - and it’s down to them to prove it.

Someone was murdered. Someone went to prison. And everyone's a suspect. Can you uncover the truth? Dear Listener - enclosed are all the documents you need to solve a case. It starts with the arrival of two mysterious newcomers to the small town of Lockwood and ends with a tragic death. Someone has already been convicted of this brutal murder and is currently in prison, but we suspect they are innocent. What's more, we believe far darker secrets have yet to be revealed.

All murder mysteries follow a simple set of rules. Grant McAllister, an author of crime fiction and professor of mathematics, once sat down and worked them all out. But that was 30 years ago. Now he's living a life of seclusion on a quiet Mediterranean island - until Julia Hart, a sharp, ambitious editor, knocks on his door. His early work is being republished and together the two of them must revisit those old stories: an author hiding from his past and an editor keen to understand it.

Richard is a middle-aged Englishman who runs a B&B in the fictional Val de Follet in the Loire Valley. Nothing ever happens to Richard, and really that’s the way he likes it. One day, however, one of his older guests disappears, leaving behind a bloody handprint on the wallpaper. Another guest, the exotic Valérie, persuades a reluctant Richard to join her in investigating the disappearance. Richard remains a dazed passenger in the case until things become really serious and someone murders Ava Gardner, one of his beloved hen...and you don’t mess with a fellow’s hens!

Canon Daniel Clement is rector of Champton. He has been there for eight years, living at the rectory alongside his widowed mother—opinionated, fearless, ever-so-slightly annoying Audrey—and his two dachshunds, Cosmo and Hilda. When Daniel announces a plan to install a lavatory in church, the parish is suddenly (and unexpectedly) divided: as lines are drawn in the community, long-buried secrets come dangerously close to destroying the apparent calm of Champton. And then Anthony Bowness is found dead at the back of the church, stabbed in the neck with a pair of secateurs.

Welcome to No.12 rue des Amants. A beautiful old apartment block, far from the glittering lights of the Eiffel Tower and the bustling banks of the Seine. Where nothing goes unseen, and everyone has a story to unlock.

Chemist Elizabeth Zott is not your average woman. In fact, Elizabeth Zott would be the first to point out that there is no such thing. But it's the early 1960s and her all-male team at Hastings Research Institute take a very unscientific view of equality. Except for one: Calvin Evans; the lonely, brilliant Nobel-prize-nominated grudge-holder who falls in love with—of all things—her mind. True chemistry results.

When the kids are grown and Mercy Garrett gradually moves herself out of the family home, everyone determines not to notice. Over at her studio, she wants space and silence. She won't allow any family clutter. Not even their cat, Desmond. Yet it is a clutter of untidy moments that forms the Garretts' family life over the decades, from giving a child a ride to a painstaking Easter lunch, a fateful train journey to an unexpected homecoming. And it all begins in 1959, with a family holiday to a cabin by a lake.

1944, in the ruined wine cellar of a Tuscan villa, as bombs fall around them, two strangers meet and share an extraordinary evening. Ulysses Temper is a young British soldier; Evelyn Skinner is a sexagenarian art historian and possible spy. She has come to Italy to salvage paintings from the wreckage and relive memories of the time she encountered EM Forster and had her heart stolen by an Italian maid in a particular Florentine room with a view.

There has never been a murder on Alderney. It's a tiny island, just three miles long and a mile and a half wide. The perfect location for a brand new literary festival. Private investigator Daniel Hawthorne has been invited to talk about his new book. The writer, Anthony Horowitz, travels with him. Very soon they discover that not all is as it should be. Alderney is in turmoil over a planned power line that will cut through it, desecrating a war cemetery and turning neighbour against neighbour.

When editor Susan Ryeland is given the tattered manuscript of Alan Conway's latest novel, she has little idea it will change her life. She's worked with the revered crime writer for years, and his detective, Atticus Pund, is renowned for solving crimes in the sleepy English villages of the 1950s. As Susan knows only too well, vintage crime sells handsomely. It's just a shame that it means dealing with an author like Alan Conway.... But Conway's latest tale of murder at Pye Hall is not quite what it seems.

When pregnant Saffron Cutler moves into 9 Skelton Place with boyfriend Tom and sets about renovations, the last thing she expects is builders uncovering a body - two bodies, in fact. Forensics indicate the bodies have been buried at least 30 years. Nothing Saffy need worry herself over. Until the police launch a murder investigation and ask to speak to the cottage's former owner - her grandmother, Rose. Rose is in a care home, and Alzheimer's means her memory is increasingly confused. She can't help the police, but it is clear she remembers something.

The London Silver Vaults - for well over a century, the largest collection of silver for sale in the world. It has more locks than the Bank of England and more cameras than a celebrity punch-up. Not somewhere you can murder someone and vanish without a trace - only that's what happened. The disappearing act, the reports of a blinding flash of light and memory loss amongst the witnesses all make this a case for Detective Constable Peter Grant and the Special Assessment Unit.

When she's not digging up bones or other ancient objects, Ruth Galloway lectures at the University of North Norfolk. She lives happily alone in a remote place called Saltmarsh overlooking the North Sea and, for company; she has her cats Flint and Sparky, and Radio 4. When a child's bones are found in the marshes near an ancient site that Ruth worked on ten years earlier, Ruth is asked to date them.

Ryan Wilkins grew up on a trailer park, a member of what many people would call the criminal classes. As a young Detective Inspector, he's lost none of his disgust with privileged elites - or his objectionable manners. But he notices things; they stick to his eyes. His professional partner, DI Ray Wilkins, of affluent Nigerian London heritage, is an impeccably groomed, smooth-talking graduate of Balliol College, Oxford. You wouldn't think they would get on. They don't. But when a young woman is found strangled at Barnabas Hall, they're forced to.
