Monk and Sharona are called to the home of Susan Molloy, the ex-wife of popular TV star Brad Terry. Once there, they learn that Susan was stabbed inside the house while Brad was out front dealing with the paparazzi -- that is, until everyone heard Susan's screams. The evidence points to a break in, but Monk thinks otherwise. Monk and Sharona pay a visit to the set of Brad's hit TV show, "Crime Lab S.F." There, they learn that the show is celebrating its 100th episode, which in turn means a VERY big payday for Brad -- a payday he's likely unwilling to share with his ex. Monk thinks he's got him, but when the TV star volunteers for a lie detector test and passes with flying colors, it's Monk who's been had.
