London. 22nd December. Chief Inspector Brett Nightingale and Sergeant Beddoes have been called to a gloomy flat off Islington High Street. An elderly woman lies dead on the bed, and her trunk has been looted. The woman is Princess Olga Karukhin - an emigrant of Civil War Russia - and her trunk is missing its glittering treasure... Out in the dizzying neon and festive chaos of the capital a colourful cast of suspects abound: the downtrodden grandson, a plutocratic jeweller, Bolsheviks with unfinished business? Beddoes and Nightingale have their work cut out in this tightly-paced, quirky and highly enjoyable jewel of the mystery genre.
