The notorious homicide detective Evert Bäckström is visited by his neighbour, the boy scout Edvin, who has made a macabre discovery: a woman’s cranium with a bullet hole.
Jaidee seems to have died twice, both at Ofärdsön (Misfortune Island) and during the tsunami catastrophe. Bäckström wants to interrogate the widower Daniel, but Hwass puts a stop to it as the tsunami is a sensitive issue.
Bäckström travels to Thailand to dig for clues about the circumstances around Jaidee’s life and death. Meanwhile, the investigative team in Stockholm is following up on another lead – the missing Asian woman Mi Mi.
Bäckström has a theory about what might have happened to Jaidee – that she might have faked her own death in the tsunami. But the team is sceptical and Bäckström can’t prove anything. Yet.
Bäckström has been suspended, but can’t stop himself from helping the homicide investigation – now with the young boy Edvin in tow.
Bäckström is heartbroken by a great betrayal, but the work must still be done. Important questions are still to be answered. Who killed Jaidee? And why?
