Strangers is a British television crime drama series, principally written and created by Murray Smith, and first broadcast on ITV on 5 June 1978.

The series, featuring the characters of Detective Sergeant George Bulman (Don Henderson) and his assistant Detective Constable Derek Willis (Dennis Blanch), was a spin-off from the 1976 TV series The XYY Man, adapted from the novels of Kenneth Royce.

I was sent here to be a stranger in town, a face they didn't recognise ..." - George BulmanThe series began life as a fairly standard police drama, with Bulman positioned as its eccentric lead.

The series' premise centred around a group of police officers, including Bulman and Willis, known as 'Unit 23', who are brought together from different parts of the country to Manchester to infiltrate areas and investigate crimes that familiar local detectives could not.

The second series, shown in early 1979, introduced WDC Vanessa Bennett, played by Fiona Mollison, who replaced Frances Tomelty.
