Jamaican Marlon James has won the prestigious Man Booker Prize, in a ceremony on Tuesday evening in London.
A brief History of Seven Killings, the 686-page novel, is about crime and violence inspired by the real-life assassination attempt against Bob Marley
Professor Michael Wood, who chaired the panel, said choosing the winner from the shortlist of six took less than two hours.
He told reporters:"We didn't have any difficulty deciding; it was actually a unanimous decision".
The novel, described as "a fictional history" of Marley's attempted murder in 1976", has a character list featuring drug lords, beauty queens and CIA agents, and stretches from Jamaica to New York and Miami at the height of the trade in crack cocaine
He will receive £50,000 for winning the award.
