James Bond seems to have become a problem. Obviously, a literary character that generates billions of dollars over more than six decades is not the worst sort of problem to have, but he presents a problem all the same. Since the death of Ian Fleming in 1964, Bond has passed through the hands of numerous authors – four of them since 2008. Sebastian Faulks, Jeffery Deaver and William Boyd wrote a single novel each, and now we get Trigger Mortis, Anthony Horowitz’s attempt at reviving the cold war relic. The truth is that, payday aside, stepping into Fleming’s blade-heeled brogues seems a thankless business. It’s not that Fleming is exactly inimitable, but the parts of his style that are easy to pastiche are also intolerably obnoxious, while the things that are worth copying are as elusive as they are distinctive.
