Struggling artist Harry Field is found murdered and thrown off an overpass but recent rains and a dry body lead Morse to conclude he was killed over a week earlier.
Among the suspects in the murder of a Greek chef and his sister are a Ancient Greek scholar, a dodgy British entrepreneur, and a Greek shipping magnate.
Morse and Lewis go to Australia to find a witness who has been in witness protection for ten years, but this is one witness who doesn't want to be found.
