Hypothermia (Inspector Erlendur Series No. 6)

Inspector Erlunder has spent his entire career struggling to evade the ghosts of his past. But ghosts are visiting him, both in the form of a seance attended by a dead woman and also in the reemerging puzzle of two young people who went missing 30 years ago. And there's the ghost of the detective's disastrous marriage, which, despite the pleas of his drug-addled daughter, he is unwilling to confront. In addition, he's still obsessed with the disappearance of his brother, who vanished without a trace when they were boys.
