On April 13th 1919, the British Indian Army opened fire on a crowd attending an unauthorised public meeting in Amritsar. Over 1,000 unarmed Indians were killed. Among the survivors was a young man who made a vow of vengeance that would ultimately prove successful. Prompted by her own family connections to the Amritsar massacre, Anita Anand tells the remarkable story of one Indian’s twenty-year quest for revenge.
