April 1941, London. In an air raid shelter beneath Whitechapel Road, a woman's mutilated body is found, evoking grim memories of Jack the Ripper. Detective Chief Inspector Coburg and Sergeant Lampson are dispatched from Scotland Yard to investigate. In the dark tunnels, they discover a battered Victorian doctor's bag filled with surgical tools, but has it been deliberately abandoned? As more victims emerge, the pressure mounts to solve the case quickly. But their task grows more complex when King George and Prime Minister Winston Churchill enlist their help in a separate, puzzling inquiry, one that may also lead back to the shadowy streets of Whitechapel.
