The fantastic fourth classic instalment in the Martin Beck detective series from the 1960s – the novels that have inspired all crime fiction written ever since.The Martin Beck series is widely recognised as the greatest masterpiece of crime fiction ever written. These are the original detective stories that pioneered the detective genre and inspired writers from Agatha Christie to Henning Mankell; Graham Greene to Jonathan Franzen. Translated into 35 languages, they have sold over 10 million copies around the world.Written in the 1960s, they are the work of Maj Sjowall and Per Wahloo – a husband-and-wife team from Sweden. The ten novels follow the fortunes of the detective Martin Beck, whose enigmatic, taciturn character has inspired countless other policemen in crime fiction. The novels can be read separately, but do follow a chronological order, so the reader can become familiar with the characters and develop a loyalty to the series. Each book will have a new introduction in order to help bring these books to a new audience.On a cold and rainy Stockholm night, nine bus riders are gunned down by an unknown assassin. The press, anxious for an explanation for the seemingly random crime, quickly dubs him a madman. But Martin Beck of the Homicide Squad suspects otherwise: this apparently motiveless killer has managed to target one of Beck's best detectives – and he, surely, would not have been riding that lethal bus without a reason.With its wonderfully observed lawmen, its brilliantly rendered felons and their murky Stockholm underworld, and its deftly engineered plot, 'The Laughing Policeman' has long been recognised as a classic of the police procedural.
