Mrs B, landlady of the Marigold Cottages, only rents to favoured tenants, and they’re an eccentric (read: odd, slightly broken) bunch. There’s anxious playwright Sophie, agoraphobe over-sharer Hamilton, single mum and sculptor Ocean, perfectionist Lily-Ann, and the ever-mysterious Nicholas. Life in the cottages is peaceful though, until hulking, fresh-out-of-prison Anthony moves in and a dead body turns up.

Anthony is arrested and Mrs B, convinced of his innocence, promptly confesses to the crime herself. Horrified, her tenants band together to clear her name, forming the somewhat haphazard ‘Marigold Cottages Murder Collective’. But as they dig deeper and a second body is discovered, further secrets are unearthed.

Can this motley collection of amateur sleuths solve the case before one of them becomes the next victim?
