Magnum, P.I. Season 8 Episode 7

A Girl Named Sue

Magnum is hired by an attractive woman to find the missing will of her late father, who was recently killed in a suspicious boating accident - which she suspects her brother of being behind, in order to steal the will. Working on the case, Thomas finds that former client Susan Johnson – whom he was once locked in a bank vault with – 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 rather love-hate relationship to one side and team up to solve the case of sibling rivalry...
