Michelle Shephard of the Toronto Star was on top of the “war on terror” story before that name had been coined, covering it even in its most dangerous corners — places like Mogadishu and Sanaa — and demonstrating a fearlessness and tenacity that few national-security reporters can match. In her new book, A Decade of Fear: Reporting from Terrorism’s Grey Zone, Shephard displays deep insight and an irrepressible sense of humor as she moves through the high and low points of America’s transformation in the decade after 9/11. I put six questions to Shephard about her book.
