The Moonstone.

A great yellow diamond, gifted on a birthday and gone by morning, throws a respectable household into suspicion and dread. Wilkie Collins's The Moonstone is often called the first true detective novel, and it has lost none of its ingenuity.

What it's about

A precious gem with a long and bloody history in India passes to a young Englishwoman on her birthday, only to disappear from her family's country house that very night. As an eccentric police detective investigates, the mystery is told through a sequence of narrators, each recounting the events from their own vantage, their partial testimonies gradually assembling into a solution few will anticipate.

Themes

Collins probes colonial plunder and its lingering curse, the unreliability of witness and memory, and the secrets that hide behind Victorian propriety. Reputation, obsession and the limits of surface respectability all come under scrutiny.

Why it still matters

The novel established devices the whole genre would inherit, from the country-house crime to the brilliant detective and the multiple-narrator structure. It is a founding text that also happens to be a genuine pleasure to read.

Who it's for

Mystery enthusiasts, admirers of Victorian fiction, and anyone curious about the origins of the detective story will find The Moonstone richly satisfying.
