Our Kind of Traitor is a reminder if such a thing were needed that John le Carré is comfortably still at the top of the tree in arena of the intelligent thriller; he is still writing books for readers who want some texture to their genre reading. But to rehearse the old debate -- is le Carré a genre writer or simply a first-rate novelist? Very few would now argue with the latter assessment. The Spy who Came in from the Cold, his first real-calling card book, took the … mehrworld of espionage thrillers by storm back in 1963, and that brilliantly written examination of the betrayal and duplicities of the Cold War both changed the face of the spy novel and marked le Carré out as the essential writer in the field a badge hes sported ever since. Subsequently, the much-acclaimed series of novels featuring the subtle spymaster George Smiley (inaugurated with Tinker, Tailor, Soldier, Spy in 1974) made much else in the field seem superficial and unambitious. While there was a move away from the pared-to-the-bone precision of the earlier books, the sprawling canvas of the Smiley sequence allowed the author to add new levels to the popular novel, making them as rich as more overtly literary fare.After recent work taking on American foreign policy (a bête noir of the author) and the big pharmaceutical companies, le Carré has returned to the concision of his early work, and in Our Kind of Traitor has delivered one of his most sheerly satisfying novels in years.Britain is suffering under the recession, and a young couple a leftish academic and his girlfriend (who is in the legal profession) escape a depressed UK for a leisurely break on the Caribbean island of Antigua. But a meeting with a Russian millionaire by the name of Dima plunges the couple down the rabbit hole in a dizzying, picaresque odyssey in which the worlds of the City of London and the shadowy corridors of espionage collide.In many ways, this is quite unlike any other John le Carré novel, even as it utilises familiar tropes. And the surprises here (which it would be criminal to reveal) demonstrate that one of our greatest writers to his considerable credit is refusing to stand still. --Barry Forshaw weniger
