The thrilling ninth installment in the classic Martin Beck detective series from the 1960s - the novels that have inspired all crime fiction written ever since. In this penultimate instalment of the series, Beck is drawn into a case that turns up mysterious echoes of his past cases.

The bloody murder of a police captain in his hospital room exposes the particularly unsavory history of a man who spent 40 years practicing a horrible blend of strong-arm police work and shear brutality. Nonetheless, Martin Beck and his colleagues scour Stockholm for the murderer, a demented and deadly rifleman.

A young blonde in sunglasses robs a bank and kills a hapless citizen. Across town, a corpse with a bullet shot through its heart is found in a locked room - with no gun at the scene. The crimes seem disparate, but to Martin Beck, they are two pieces of the same puzzle, and solving it becomes the one way he can escape the pains of his failed marriage and the lingering effects of a near-fatal bullet wound.

The Terrorists is the last Martin Beck mystery, finished just a few weeks before Per Wahlöö’s death. The book is, in effect, a marvelous summing up of the series. The story centers on the visit of an American senator to Stockholm. Martin Beck tries to protect him from an international gang of terrorists, while they decide that Beck too should be removed from the scene. Interwoven with this basic story are two fascinating subplots. One, a classic mini-mystery, is the story of a millionaire pornographer bludgeoned to death in his own bathtub.

The cunning incendiary device that blew the roof off a Stockholm apartment not only interrupted the small, peaceful orgy underway inside, it nearly took the lives of the building's 11 occupants. And if one of Martin Beck's colleagues hadn't been on the scene, the explosion would have led to a major catastrophe because, for reasons nobody could satisfactorily explain, a regulation fire truck has vanished. Was it terrorism, suicide, or simply a gas leak?
