In the concluding part of Sir Trevor McDonald’s documentary about the wives, girlfriends and daughters of American mobsters, he comes face-to-face with the notorious Sal Romano and his wife Marian.

Sal lived a Wolf of Wall Street-style existence, raking in millions by trading illegal stocks and shares.

The couple enjoyed the high life – ‘He was making $30 million a year,’ Sir Trevor reveals – until Sal cooperated with the FBI and entered Witness Protection.

Despite their change in circumstances, it seems Marian has no regrets.

‘I can’t turn around and say I didn’t know what he was doing,’ she admits. ‘I couldn’t have been married to a banker – it would have been boring!’
