A wrecking ball crashes through the roof of a terraced cottage in Bath and exposes a skeleton in eighteenth-century clothes. Can these possibly be the remains of Beau Nash, the so-called King of Bath, whose body is said to have ended up in a pauper's grave?

Peter Diamond, the city's most experienced detective, is ordered to investigate, but grappling with historical events causes ructions in his team until everyone is diverted by a modern killing during a fireworks display on the Royal Crescent lawn.

But Beau Nash refusesto be ignored - and when astonishing new facts emerge about the case, Bath's history is rewritten and mysteries ancient and modern are fused in a devastating climax.
