Who Killed Lenore Wingfield? - S2.E8

Wealthy Lenore is blown away by a shotgun blast while sailing on a barge in her pool, dressed as Cleopatra, and is discovered by one of the men she has befriended from the local mission. Wealthy after several marriages, but coming from hillbilly stock, the victim was planning to change her will. Was the killer her only surviving ex-husband, her sexually repressed sister, her favorite cousin or his ""down-home"" girlfriend, or the shady rival businessman who's planning on marrying off his daughter to the victim's heir? A whole flock of chickens provide a vital clue.
