Law & Order: Criminal Intent - Season 5 - Eps 21: On Fire
Goren and Eames investigate a fire at St. Gerald's which led to the death of a Church employee and soon realize that an arsonist around town is targeting churches. Throughout their investigation, they realize that St. Gerald's was the arsonist's primary target, and clues lead them to Justin Reid, who had donated $100,000 to rebuild the Church, his step-mother Regina, whom they soon learn had seduced Justin when he was only a teen, and his half-brother Glynn, who works for a clean-up crew that had worked at all the churches that were burned down shortly after they were renovated. Deakins comes under fire when an e-mail surfaces that insinuates he got Martinez (from <a href="http://www.tv.com/law-and-order-criminal-intent/to-the-bone/episode/730599/summary.html">To the Bone</a>) to lie about the Logan shooting by getting him a promotion. The e-mail is soon traced back to former cop Frank Adair (from Season 4, Ep. 22 - My Good Name), who is doing time for murder.
