The Man with the Golden Gun by Ian Fleming
A brainwashed James Bond has tried and failed to assassinate M, his boss. Now, Bond has to prove he is back on form and can be trusted again. All' 007 has to do is kill one of the most deadly free-lance hit-men in the world one Paco Pistols' Scaramanga, the Man with the Golden Gun. But, despite his licence to kill, 007 is no assassin, and, on finding the Scaramanga in the sultry heat of Jamaica, he decides to infiltrate the killer's criminal co-operative and realizes that he will have to take him out as swiftly as possible or 007 might just be the next on a long list of British Secret Service numbers that the Man with the Golden Gun has retired.
