Undercover: How I Went from Company Man to FBI Spy -- and Exposed the Worst Healthcare Fraud in US History

When John Schilling, an unassuming mid-level accountant, went to work for the Columbia Hospital Corporation, he never expected to become the catalyst for the series of “whistleblower” cases that ripped through the healthcare industry in the late 1990s. But when he unwittingly discovered that the company was siphoning billions of dollars away from Medicare and stealing from American taxpayers, he was faced with a choice: Speak up for what he believed to be right, or remain silent.

Undercover tells the story of Schilling’s harrowing journey from ordinary citizen to federal informant. The book recounts how Schilling allied himself with the FBI and the Justice Department and—unable to confide in friends or family—journeyed into an undercover world in which he carried a wire and mapped out offices for secret government raids. Suspenseful and provocative, Undercover chronicles Schilling’s nine-year ordeal that eventually led to the resignation of high-level executives and forced Columbia to return $1.7 billion dollars to the federal government.

A compelling account of one man’s decision to risk everything for the greater good, this book reveals the personal side of a thankless role that resulted, ultimately, in justice.
