A secret truth: On the early morning of August 16, 2006, Osama bin Laden was arrested in Brooklyn by the New York FBI Terrorism Task Force. They were acting on a tip called in by Barbara Janik. Her memoir, Chasing bin Laden, takes readers along with her on an emotional journey through the hidden world of lay investigations, which is charged with high-stakes puzzle solving, Arabic message boards, and anxiety-provoking collaborations with the FBI. Barbara Janik is a middle-aged masters-level historian from rural Texas. Throughout the manuscript, she cleverly integrates 177 citations that help corroborate this hidden history.
