Bombay, 1950. James Whitby, sentenced to death for the murder of prominent lawyer and former Quit India activist Fareed Mazumdar, is less than two weeks from a date with the gallows. In a last-ditch attempt to save his son, Whitby's father forces a new investigation into the killing. The investigation leads Inspector Persis Wadia of the Bombay Police to the old colonial capital of Calcutta, where, with the help of Scotland Yard criminalist Archie Blackfinch, she uncovers a possible link to a second case, the brutal murder of an African-American G.I. during the Calcutta Killings of 1946. Are the cases connected? And if Whitby didn't murder Mazumdar, then who did?
