Ep 4. The Girl Who Lived

Retired detective Steve McAndrew arrives from Glasgow to help reinvestigate one of his original cases, when the DNA of a young girl who went missing in 2003 after a university disco is found at the scene of a petrol station robbery in Clapham. It's clear that the inquiry is a very personal one for McAndrew, and although his taste for whisky, an eye for an attractive lady, an odd hobby and some dubious methods when it comes to police work rubs the team up the wrong way, his methods soon pay dividends.
