 Trevor Radford, Managing Director of the family s Radford Breweries, is found murdered in the brewery. He had been working late one evening mounting a defense against an unwelcome takeover attempt from a rival brewery. There appear to be some disagreement in the family as to whether they should sell out. His brother Stephen, an entrepreneur in his own right, thought the time had come to rid themselves of a losing proposition but their father would like to maintain the family tradition that now spans 150 years. Morse and Lewis learn that Trevor s wife was having an affair with Stephen, so there is always the possibility that there this is a crime of passion rather than greed.They also learn of a long ago claim against the business  assets.
