Following on from The Essex Murders, one of Sky Documentaries highest ever rated Originals, private investigations firm TMEYE take on another unsolved Essex murder in Who Killed Goldfinger?

On June 24th, 2015, one of Britain's most notorious criminals, John "Goldfinger" Palmer was found dead in his Essex garden. While police originally believed he died of natural causes, they eventually confirmed the case was being treated as a professional hit. 

28 years earlier, Palmer had been acquitted for his part in the infamous Brink's-Mat robbery, where he melted down millions worth of gold from the £26 million raid to sell on. He amassed a fortune so big, at one point he was ranked alongside the Queen in the Sunday Times Rich List but was finally jailed for timeshare fraud in 2001. 

As the 10th anniversary of his unsolved murder approaches, this new series re-examines his life and death, featuring exclusive testimony from some of Palmer's closest associates speaking for the first time. Private investigations firm TMEye – fresh from reinvestigating the Essex Boys murder case, which assisted in launching the CCRC to review the convictions– will lead viewers on a hunt spanning multiple countries before finally unmasking their prime suspect.
