Shadows of Doubt (2) - S3.E11

Learning that Christine's boyfriend, Adam Kirkwood, is the FBI's prime suspect in an arms smuggling operation, Peter takes Christine to Agent Rider, who informs her that George Sandler, a powerful politician, and Adam are plotting to sell arms to guerrilla forces in the Third World. After planting a bomb in the hotel basement, security chief Art Patterson anonymously tips off the hotel and personally disarms the bomb in order to make himself a hero. When Billy finds evidence pointing to Patterson, Patterson asks for Billy's resignation. Over Peter's objections, Christine agrees to plant an FBI listening device in Adam's bedroom. When Adam catches Christine, Sandler insists on killing her, but Adam arranges for Peter to take Christine to safety. At the hotel, Billy agrees to resign, but Patterson eventually confesses to Billy and leaves the hotel security in Billy's hands.
