From the producers of White House Farm and Des, The Long Shadow will depict one of the most notorious and shocking serial killer cases in the world, the hunt for Peter Sutcliffe, dubbed the Yorkshire Ripper. Between October 1975 and January 1981, police undertook the biggest manhunt in British criminal history. The search for Sutcliffe lasted six years, involved over a thousand officers and changed the way the British police worked forever. Meticulously researched and drawing upon the most extensive archive of the investigation, comprising of hundreds of case files, interview transcripts and police reports, The Long Shadow is the first definitive account of a case that shook Britain.
