In 1919, Punjab's Lieutenant Governor Sir Michael O'Dwyer sent troops to Amritsar to bring the politically turbulent city to heel, precipitating a clash that killed hundreds of civilians. According to legend, 18-year-old Sikh orphan Udham Singh was injured in the attack, and vowed to kill the men responsible. The truth, as Anita Anand reveals in this winner of the PEN Hessell-Tiltman Prize, is more complex—but no less dramatic. Here Anand traces Singh's worldwide journey until, in March 1940, the assassin arrives in front of O'Dwyer himself in a London hall.
