Unnatural Causes - S6.E7

Commander Dalgleish of Scotland Yard investigates the apparent murder of a well-known author who is found floating in a dinghy with his hands chopped off. The man, Maurice Seton, had recently been ejected from a private club when he was caught photographing some of its members at the gambling tables. The club had been under suspicion of laundering large amounts of cash and had been the object of a police investigation for some time.
