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.".
