The Yellow Diamond 
A Crime of the Super-Rich

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.
