Magnum, P.I. (1980): Season 2, Episode 11

2 - 11: The Sixth Position

As a favor to Robin Masters, Magnum finds himself acting as bodyguard to a famous ballerina after she's had several attempts made on her life, and T.C.'s previously undeclared love of ballet comes in handy, with him more than willing to help Magnum out on a case for once. Meanwhile, Rick accepts a job on Magnum's behalf to investigate a woman's husband, but Magnum becomes suspicious that the timing of the job is rather too coincidental and comes to suspect that he's been hired for another reason.
