Jonathan Creek: The Curious Tale of Mr Spearfish (1999)

A man who claims to have sold his soul to the Devil has a remarkable run of good luck — ranging from finding ancient treasure in his backyard to surviving a point-blank range shooting — but Jonathan and Maddy believe his success may be coming from a more Earthly source than Hell. Adam, meanwhile, has to deal with a rather awkward court case where a woman claims he asked her to perform unnatural acts with a kipper.
