7. A Girl Named Sue

Magnum is hired by the attractive Melissa Wainwright ( Shelley Smith ), to find the missing will of her late father, William ( George Coe ), who was recently killed in a suspicious boating accident, which she suspects her brother Arthur (John Calvin) of being behind, in order to steal the will. Working on the case, Thomas finds that former client Susan Johnson ( Carol Burnett ) - with whom he was once locked in a bank vault - is now a fellow private investigator, and is working on the same case - for the brother, who suspects his sister as responsible for their father's death. The two P.I.s are soon locked in a battle of wills as they both race to solve the investigation first, but the pair are forced to put their love-hate relationship to one side and team up to solve the case of sibling rivalry.
