James and Robson Green were seen filming scenes on the snow-covered set, in deep conversation next to a 1950s car- reflecting the era it is based on.

One scene saw Robson running through the street, in what appeared to be a particularly heavy snow flurry. 

Clad in a vintage style brown pinstripe suit, a camel overcoat and a top hat, Robson cut a smart figure.

The final episode of the last season saw Geordie shot on duty.

A year on, he appears to have put it behind him but underneath his carefree exterior there are new feelings of vulnerability, and this puts a strain on his relationship with wife Cathy and his friendship with Sidney.

The six new episodes are being filmed in London and Grantchester as well as in Cambridge's city centre.
