Ambitious DI Joseph Chandler is assigned an open-and-shut case, the killing of a woman in the East End of London. Get a quick result, he is told, and you will get the promotion you have been waiting for. Unfortunately for him, however, things don’t turn out to be so straight forward. The investigation quickly runs out of suspects until Edward Buchan, a renowned Ripperologist, draws the police’s attention to the similarities between the Jack the Ripper killings in 1888 and the modern-day murder that Chandler is investigating. The race begins to catch the copycat killer before he strikes again.
