Colson Whitehead is one of the rare authors to win the Pulitzer Prize twice. The first time was for his novel "The Underground Railroad" in 2017, loved by Barack Obama and Oprah Winfrey and made into a TV series by Oscar-winning director Barry Jenkins. It led to him being on the cover of Time Magazine, the first author in nearly a decade to grace the front page since Jonathan Franzen. Colson Whitehead was honoured again for "The Nickel Boys" in 2020 – adapted into a film due out in the autumn. He is in Paris at the Festival America and for the French release of his novel "Crook Manifesto". The multi-award-winning American author speaks to Eve Jackson about his crime trilogy set in Harlem.
