For most thriller writers, foreign locations are just an excuse for showing exotic customs and local colour, even if the themes, and for the most part the characters,are really western with a lick of paint. John Burdett's books, ever since Bangkok 8, have always stood apart. He has always attempted to describe Thai society from the inside, in its own terms, and with crimes both committed and solved according to Thai norms. His detective, Sonchai Jitpleecheep, may be half-western, but his mind-set, a mix of Buddhism, mysticism, folk-religion and the customs of an old, proud and complex society, makes him not only a unique detective but an unnerving one. As the books have progressed, the western dimension has become less and less significant to the point where, in Burdett's new book, we find ourselves increasingly falling into Jitpleecheep's way of thinking, and begin seeing westerners, as he does, as bizarre, unhappy, often pathetic beings. Burdett has been criticised for this, as for the incessant invocation of the "farang" who is presumed to be reading the book. But this rather misses the point. Jitpleecheep is not Burdett, any more than Maigret is Simenon, and Jitpleecheep is a complex, flawed character who makes mistakes and misjudgements just like the rest of us. In the Godfather of Kathmandu, moreover, our hero is reeling from personal tragedy and wracked by self-doubt about his ambiguous role, half policeman, half factotum for his criminal boss, the satanic Colonel Vikorn. He can be forgiven a few moments of despair and exasperation. The book isn't perfect - the explanation of the central murder seems unduly complex, for example - but it has the integrity which comes from relentlessly doing its own thing. This is hardcore Burdett, Thai society from the inside, with ghosts, demons, reincarnation, and the workings of karma, finance, crime and a complex social system hopelessly entwined with each other. It makes no concessions to the reader who expects western plot-devices or motivations, and it's all the better for it.
