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 obvious attempt to stop the book ever being written. As they investigate, they find themselves in the middle of a highly mysterious situation. 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 centre of the mystery...

At the urging of the students in the private investigation class that Thomas is teaching at a local college, Thomas takes on the investigation into the disappearance of a fellow student's fiancé as the class's field work. The teacher and his pupils soon discover that while the student's fears that her fiancé is having an affair are unfounded, this anything-but-textbook case involves a man sought after by both sides of the law for trying to prevent a crime.
