Martin Reid was a criminal psychologist, studying the behaviour of criminals. He was employed by the Metropolitan Police which allowed him to visit New Scotland Yard, his sole purpose for these visits was to go to the Crime Museum within the building, and there he fed his obsession, his strange interest with the crimes of Jack the Ripper. On one visit he met George Saunders, an ex-police officer who also had an interest in Jack. After a short conversation they agreed to meet at a public house in Whitechapel, there George would give Martin the opportunity of a lifetime, to go back in time to Victorian London, to try to identify Jack before he committed his first murder. The journey back is mixed with horror and excitement, both men knowing where Jack would strike, waiting to catch a glimpse of the most notorious of serial killers, this is their story.
