An adulterous couple, Nina Adler and Martin Rittner,are blown up in a beach-house explosion and foul play is suspected. Peter,Nina's husband and Martin's business partner, is a thuggish,dodgy sort but Rittner's wife gives him an alibi. A tramp,subject to memory losses,known to be in the area at the time of the murders,who participated in scams for Adler and Rittner, is also killed but again Adler has an alibi. Wallander learns that the key to the murders lies in a particularly despicable business fraud and a man out for terrible revenge for deeply personal reasons.
