Detective Superintendent George Quinn - Mayfair resident and dandy with a razor-sharp brain - has set up a new police unit, dedicated to investigating the super-rich. When he is shot in mysterious circumstances, DI Blake Reynolds is charged with taking over. But Reynolds hadn't bargained for Quinn's personal assistant - the flinty Victoria Clifford - who knows more than she's prepared to reveal...The trail left by Quinn leads to a jewellery theft, a murderous conspiracy among some of the most glamorous (and richest) Russians in London - and the beautiful Anna, who challenges Reynolds' professional integrity. Reynolds and Clifford must learn to work together fast - or risk Quinn's fate.

Set in the heart of twenty-first-century Mayfair, a world of champagne, Lamborghinis and Savile Row suits, The Yellow Diamond is a brilliant new venture from one of our best loved crime authors - meticulously plotted, wonderfully humane and hugely enjoyable.
