The third Inspector Erlendur book, Voices, by Arnaldur Indriðason, is billed as a thriller, but is really a subtle, layered psychological novel. This is the third in a series (the other English titles: Jar City, Silence of the Grave) of Icelandic mysteries, Erlendur is called to investigate a murder in a posh Reykjavík hotel, he decides to stay there for the investigation, not wanting to go home to his "empty hole" of an apartment during the Christmas season. By restricting his main character to one location, Arnauldur forces us to go inward with Erlendur, as he confronts his own past, as he explores the motivations of the murder, and reveals the background of the victim.
Arnaldur Indriðason is getting better with each book in the series, this book lacks the broader Icelandic settings of the others, but probes the Inspector's internal landscape deeper. This is a great series, and I am looking forward to many more.
