When the seventh officer of Hegemon is assassinated in the Temple Round Church, the body is taken under the London Bridge. Meanwhile, in Portsmouth, the Brainy Boy gang is found not guilty of assaulting Professor Violet Smith, leading former Detective Inspector Cherry Clarke to take matters into her own hands.
However, each of the Brainy Boys is brutally assassinated soon after. As the retired First Sea Lord of the Admiralty is also killed, the discovery of seven severed pinkie fingers sets off alarms in the Mammon crime profiling and data storage programme. With the help of Bong from the Serious Crime Unit of Scotland Yard and Grace Church of MI5, Cherry investigates the mysterious links between these crimes and the Royal Peculiar.
But when Professor Smith asks her to become her avuncular, Cherry realizes she might be in over her head. Full of suspense, twists, and turns, 'Choir Of Assassins' is a must-read for fans of gripping mysteries.
