DI Neville Parker has more crimes to solve on the blissful island of Saint Marie, kicking off with the mysterious death of a celebrity astronomer. And on a quiet hillside on the island, a bunch of Preppers are digging in for the apocalypse when one of them is killed. There’s also a baffling killing on a boat, a famous singer who finds herself under suspicion, a shocking murder at a wedding, and a simple domestic murder – that turns out to be Neville’s greatest ever challenge.
