The seventh classic instalment in this genre-changing series of novels featuring Detective Inspector Martin Beck.

On a quiet night a high-ranking police officer, Nyland, is slaughtered in his hospital bed, brutally massacred with a bayonet. It's not hard to find people with a motive to kill him; in fact the problem for Detective Inspector Martin Beck is how to narrow the list down to one suspect. But as he investigates Nyland's murder he must confront whether he is willing to risk his life for his job.

Written in the 1960s, these masterpieces 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.
