The latest series (the 5th) of Jonathan Creek started on 14th Feb 2004. At least in the first
episode, Shipley windmill, which has served as the title character's home in previous series,
did not appear.
However, there's also a website from the BBC to
accompany the series, and a new DVD box set of
Series 1 and 2
in which the windmill does feature.
