10x2 - Midsomer Murders

Faith Alexander arrives in Midsomer Deverell to visit her estranged Uncle Rex, much to the surprise of his friends and associates who had been told she was dead. The problem is Rex is missing and Barnaby's initial investigation into his disappearance becomes more sinister when Rex's body is found at the bottom of the weir. The case becomes more complicated as it appears the eccentric Rex left several different wills and everyone wants a slice of his estate. Was this the reason for murder, or is it related to a family feud from 40 years ago? What was the secret of the feud? Those who know are not saying but someone is prepared to commit further murders to ensure it is not revealed.
