A spooky Easter treat for Alan Davies fans with this one-off outing from the sporadic murder mystery series. Once again magic consultant Jonathan Creek (Davies) is inveigled into joining forces with psychic investigator Joey Ross (Sheridan Smith) when a young woman (Natalie Walter) working for a famous crime writer (Paul McGann) appears to become possessed by a vengeful spirit from Victorian times. As ever this is more howdunit than whodunit, with the convoluted plot very much designed to keep you guessing all the way to the end.
