Edward 'Ed' Buchan
Ripperologist who offers his aid to Chandler. As a young man, he made a documentary about the Kray twins.
Season 1
After passing the scene of a recent murder Buchan turned up at the police station calim to know all about the murder. In an interview with Chandler and Miles he prefectly describes the murder, complete with unreleased details, but is thrown out by Miles when he reveals his profession and that his description was of the first offical Ripper murder.
Chandler keeps a copy of Buchan's book and attends one of his tours and takes advice on a possible scenario for the next murder. When it occurs Buchan becomes both a resource and a suspect. Chandler identifies that Buchan might be simply in tune with the murderer's ideas or even a role model (his theories appear to be those of the murderer as to what was ripper canon and what the ripper's intentions were). Mile sis far more secptical and bleaves him either a hinderance or the purpertraitor.
As the season ends the killer is revealed to be a fan of Buchan and even uses him to enable one of the harder to achieve murders, much to Buchan's distress.
