IMDB entry[]

Although most sources (including BBC Radio) confirm that this adaptation is a radio adaptation, there is an IMDB entry for it claiming it to be a television series (IMDB tt12157412). Presumably this is because IMDB accepts entries for podcasts and this programme, being available on audioCD is considered a podcast.
