LONDON, 1942.

A killer going by the name of 'Crimson Jack' is stalking the wartime streets of London, murdering women on the exact dates of the infamous Jack the Ripper killings of 1888. Has the Ripper somehow returned from the grave? Is the selfstyled Crimson Jack a descendant of the original Jack or merely a madman obsessed with those notorious killings?

In desperation Scotland Yard turn to Sherlock Holmes, the world's greatest detective. Surely he is the one man who can sift fact from legend and track down Crimson Jack before he completes his tally of death. As Holmes and the faithful Watson tread the blacked out streets of London, death waits just around the corner.
