It was 25 years ago that the novelist and television sitcom writer Peter Tinniswood first arrived in Sheffield as a young reporter. So began his love affair with the city on which he was to draw for so much of his fiction and fun about the Brandon family and Uncle Mort in the television series "I Didn't Know You Cared". The writer himself enters the fantasy world of the Brandons and, with two of his characters, travels back to the city of his imagination.
