Hardcastle and McCormick

Mark surprises the judge when he not only qualifies for, but becomes a winner on, The 1 Million Dollar Trivia Master, a television game show. Unbeknownst to Mark, veteran game show producers Harry Baxter and Art Healy, envisioning big ratings, decide to help the ex-race car driver along once they discover that the audience is cheering for him to succeed. To guarantee a winning streak, the producers have Hardcastle's estate bugged and begin basing their questions on Mark's home practice sessions. Although Hardcastle quickly realizes that something is amiss, Mark is unwilling to accept that the game is rigged. After Diane Templeton, one of the trivia show's employees, dies under mysterious circumstances, Mark turns around and admits that something is seriously wrong. Searching the show's offices, Hardcastle finds out why Diane was killed: She had obtained a tape proving the show is fixed. Meanwhile, Baxter and Healy discover that Bryce Benson, the shows host, had taken their plan to a deadly conclusion by killing Diane. Not wanting to face murder charges, the producers decide to tell Hardcastle everything. During the taping of the show's final round, Mark, giving up his chance to be a big winner, reluctantly helps the police stop Benson. Hinting at the series eventual conclusion, Mark jokes about going to law school in this episode.
