Book excerpt: The shocking sixth novel in the Martin Beck mystery series by the internationally renowned crime writing duo by Maj Sjöwall and Per Wahlöö, finds Beck investigating a brutal assassination. With an introduction by Arne Dahl. When Viktor Palmgren, a powerful Swedish industrialist is shot during his after-dinner speech in the luxurious Hotel Savoy, it sends a shiver down the spine of the international money markets and terrifies the tiny town of Malmo. No one in the restaurant can identify the gunman, and local police are sheepishly baffled. That's when Beck takes over the scene and quickly picks through Palmgren's background. What he finds is a web of vice so despicable that it's hard for him to imagine who wouldn't want Palmgren dead, but that doesn't stop him and his team of dedicated detectives from tackling one of their most intriguing cases yet.
