Matlock (1986)

Season 7: Episode 5

Mike Wilson begs Matlock to help his wife Janice out when she is accused of a crime. Matlock approaches Janice's lawyer, who thinks Matlock is pulling his leg when he says that Mike talked to him, because Janice is on trial for killing Mike. Matlock finally accepts that he is seeing a ghost and, after doing a little investigating on his own, convinces Mike's wife to allow him to defend her. Unfortunately, Matlock has more than just a ghost to deal with. It seems almost everyone who knew Mike Wilson had some reason to kill him.
