Don’t act like Blofeld—monocled and ostentatious. We journalists love writing about eccentrics. We hate writing about impenetrable, boring people.

Guy Savelli's role in the War on Terror began when half-a-dozen strangers, within days of one another, contacted him via e-mail and telephone in the winter of 2003.
