As a publicity stunt, a novelist writes a book containing clues that can lead readers to a real life treasure. Eventually, a reader discovers the location of the buried loot, but when the treasure chest is opened amidst a flurry of reporters and news crews, the only thing inside is the body of the writer. Grey and Eddie must hunt down the killer and retrieve the treasure or Lime Street will have to pay off the contest winner.

Grey and Eddie's latest case involves a man named James Edwards, who claims he can communicate with the dead. Things turn grave when the expert they hire to disprove the psychic's ability turns up dead. The investigators must prove that Edwards murdered him to keep from being discredited, or Lime Street will have to pay him $3 million.

Legendary fighter pilot Woody Harrell is testing a new jet prototype when it suddenly vanishes from radar screens leaving Lime Street on the hook for a $200 million insurance payout. Grey and Eddie join the FAA in it's investigation and begin to suspect foul play when no wreckage can be found.
