The blackout went into effect three days before the declaration of war and transformed nocturnal London into a criminal's paradise. As the city pulled together in the face of terrible adversity, the bomb-ravaged streets became the stalking grounds for killers, rapists, looters and gangs. The number of bodies retrieved during the Blitz made it impossible for the authorities to autopsy them all, providing cover to those who worked with blades, guns and more sinister tools. Scotland Yard - its resources stretched to the limit - did its best to tackle a rogues' gallery born of bombs and blackout, and crimes that continue to fascinate from history's darkest corners. In Dark City, award-winning crime writer Simon Read paints a vivid picture of the other side of wartime London, from the Blackout Ripper and the Acid Bath Murders, to the notorious Rillington Place killer and his house of corpses.
