Magnum P.I. S02E12 - Ghost Writer

Magnum is hired by an attractive "ghost writer" who is writing a biography of eccentric millionaire Harold Farber - whom she has never met in person, communicating only via phone - when all her notes on Farber are stolen, in an attempt to stop the book ever being written. Meanwhile, T.C. has landed himself a highly lucrative, but shady, piloting job delivering chemicals to a high-rise, but the building he is making the deliveries to turns out to be at the center of the mystery.
