When Viktor Palmgren, a powerful industrialist, is casually shot during an after-dinner speech, the repurcussions -- both on the international money markets and on the residents of the small coastal town of Malmo -- are widespread. Chief Inspector Martin Beck is called in to help catch a killer nobody, not even the victim, was able to identify. He begins a systemic search for the friends, enemies, business associates and call girls who may have wanted Palmgren dead -- but in the process he finds to his dismay that he has nothing but contempt for the victim and sympathy for the murderer!
