Sjowall/Wahoo - Laughing Policeman (Martin Beck), paperback

1992

1971 Edgar Award for Best Novel 

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 Superintendent Martin Beck of the Stockholm 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 (including the inimitable Martin Beck), its brilliantly rendered felons and their murky Stockholm underworld, and its deftly engineered plot, The Laughing Policeman is a classic of the police procedural and "must reading for anyone who claims to be [a student] of the best detective fiction" (Saturday Review).
