BBC1 has commissioned four more episodes of North East-set police drama Inspector George Gently.

The series, written by Peter Flannery and based on the novels by Alan Hunter, stars Martin Shaw as a London police inspector fighting crime in Northumberland and County Durham in the late 1960s.

The new episodes will begin filming next week with a broadcast date set for next year. The most recent four-part series aired in February this year and averaged 6.5m viewers.

Gently’s sidekick DS John Bacchus, played by Lee Ingleby, will return for the new episodes.

Ingleby told “I love it. It’s fun. Me and Martin get on really well. We have fun and it’s interesting. What appeals to us is it’s not a boss and sidekick thing, there are two people who love to hate and hate to love each other and their relationship is very interesting.”

Inspector George Gently is made for the BBC by Company Pictures.
