This is a 1970s film (possibly late 1960s) about a British policeman searching for a missing girl in her 20s. It might have been a TV movie. It was in colour. I don’t remember anything other than a scene in the middle of the film, where an older woman, possibly the girl’s landlady, describes to the policeman that the girl was very popular and men would pinch her bottom. Also, a scene at the end where her body is discovered in a greenhouse.
