Another case for the lateral thinking sleuth, Jonathan Creek (Alan Davies).
This time around, Creek investigates events at a spooky country house.
When a new assistant housekeeper arrives at 'Green Lanterns', the home of a famous crime writer, she learns the house harbours the secret of an unsolved Victorian murder.
When the owner's wife is suddenly murdered, all the evidence points to the housekeeper.
It's not long, however, before Jonathan and his sceptical assistant Joey Ross (Sheridan Smith) start to dig deeper.
Sasha Beehar, Paul McGann, Doreen Mantle and Natalie Walter co-star.
