Late one night in February 2009, Ariane Ice sat poring over records on the website of Florida's Palm Beach County. She'd been at it for weeks, forsaking sleep to sift through thousands of legal documents. She and her husband, Tom, an attorney, ran a boutique foreclosure defense firm called Ice Legal. (Slogan: "Your home is your castle. Defend it.") Now they were up against one of Florida's biggest foreclosure law firms: Founded by multimillionaire attorney David J. Stern, it controlled one-fifth of the state's booming market in foreclosure-related services. Ice had a strong hunch that Stern's operation was up to something, and that night she found her smoking gun.
