High Quality Content by WIKIPEDIA articles! Crime Traveller is a 1997 science fiction detective television series produced by Carnival Films for the BBC based around the premise of using time travel for the purpose of solving crimes. Anthony Horowitz created the series and wrote every episode. He got the idea while writing an episode of Poirot. Despite having over eight million viewers on a regular basis, Crime Traveller was not renewed after its first series, because according to Horowitz, "The show wasn't exactly cut. There was a chasm at the BBC, created by the arrival of a new Head of Drama and our run ended at that time. There was no-one around to commission a new series...and so it just didn't happen." Other sources cited at the time that the BBC was concerned by a steady decrease in viewing figures from 11m to 7m by the end of the show's run, and feared viewing figures would continue to decline if the series was recommissioned.
