The gripping story of the 1983 Brink's-Mat robbery, where armed thieves stole £26 million of gold bullion and diamonds from a depot near Heathrow, was dramatised in BBC1 drama series The Gold, costarring Tom Cullen as ruthless criminal John 'Goldfinger' Palmer.

Now, this three-part true-crime series looks at the murder of Palmer, the goldsmith who was accused of laundering much of the money from the heist by melting down the bullion and selling it on.
