'People are going to be amazed'

Charlotte Spencer leads a stellar cast as the search for missing gold continues in the hit crime drama

- 

The mystery of the Brink's-Mat robbery may have been solved in the first series of BBC One's The Gold - but the case is far from sealed shut.

Hugh Bonneville and Charlotte Spencer return as London detectives in the drama’s second series, inspired by the real-life 1983 robbery in which £26 million worth of gold bullion was stolen from a warehouse in Heathrow. While Micky McAvoy’s gang were convicted over the theft in series one, only half of the missing gold was found.

"A lot of people have said, 'Oh my God, why is there a second series?" says Charlotte, who plays detective Jennings. "A lot of people don't realise that they actually only found half of the gold.

"There’s a whole other half - a whole other story. There are many stories that happen from this and I think people are going to be amazed at just how far it spreads and how much this web keeps growing."

Despite filming the show’s first series over two years ago, it didn’t take long for Charlotte, 33, to get back into character as the unflappable Nicki Jennings who's incorruptable despite her family's criminal roots.
