The Indian Clerk : On a January morning in 1913, G.H. Hardy - eccentric, charismatic, and, at thirty-seven, already considered the greatest British mathematician of his age - receives in the mail a mysterious envelope covered with Indian stamps. Inside he finds a rambling letter from a self-professed mathematical genius who claims to be on the brink of solving the most important unsolved mathematical problem of all time. Hardy is determined to learn more about the mysterious Ramanujan and, if possible, persuade him to come to Cambridge. The Indian Clerk takes an extraordinary slice of history and transforms it into an emotional and spellbinding story.
