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, London's Park Avenue, 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.
