In a peaceful retirement village, four unlikely friends meet up once a week to investigate unsolved killings. But when a local property developer shows up dead, 'The Thursday Murder Club' finds themselves in the middle of their first live case. The four friends, Elizabeth, Joyce, Ibrahim and Ron, might be octogenarians, but they still have a few tricks up their sleeves. Can our unorthodox but brilliant gang catch the killer, before it's too late?

Steve Wheeler is enjoying retired life in the New Forest. He does the odd bit of investigation work, but he likes his familiar habits and routines. His days of adventure are over: adrenaline is daughter-in-law Amy’s business now. Amy Wheeler thinks adrenaline is good for the soul: she doesn’t stay still long enough for a habit or routine. She’s currently on a private island keeping world-famous author Rosie D’Antonio alive. Which was meant to be an easy job. Then a dead body, a bag of money, and a killer with their sights on Amy mean an end to Steve’s quiet life.

I was dreading the Cunningham family reunion even before the first murder. Before the storm stranded us at the mountain resort. The thing is, us Cunninghams don't really get along. We've only got one thing in common: we've all killed someone. My brother, my step-sister, my wife, my father, my mother, my sister-in-law, my uncle, my step-father, my aunt. Even me. When they find the first body in the snow, it's clear that only a Cunningham could have committed the crime—and it's up to me to prove it. There are plenty of killers in my family. But only one murderer.

Retired publisher Susan Ryeland is living the good life. She is running a small hotel on a Greek island with her long-term boyfriend, Andreas. It should be everything she's always wanted - but is it?

Beartown is a small town in a large Swedish forest. For most of the year it is under a thick blanket of snow, experiencing the kind of cold and dark that brings people closer together - or pulls them apart. Its isolation means that Beartown has been slowly shrinking with each passing year. But now the town is on the verge of an astonishing revival. A bright new future is just around the corner. Until the day it is all put in jeopardy by a single, brutal act. It divides the town into those who think it should be hushed up and forgotten, and those who'll risk the future to see justice done.
