The Thursday Murder Club (2020)

Four residents of Coopers Chase turn their weekly discussion of old crimes into a live investigation. Their different working histories and friendships give the retirement village a life beyond the suspect list, and the local police become part of that wider circle. Osman balances jokes with loneliness, bereavement and difficult choices, so the warmth does not mean nobody suffers. Begin here and read in order if you want the relationships to accumulate.
