Book excerpt: In this stunning prequel to his critically acclaimed Inspector Erlendur series, Arnaldur Indridason gives devoted fans a glimpse of Erlendur as a young, budding detective. The beat on the streets in Reykjavik is busy: traffic accidents, theft, domestic violence, contraband ... And an unexplained death. When a tramp he met regularly on the night shift is found drowned in a ditch, no one seems to care. But his fate haunts Erlendur and drags him inexorably into the strange and dark underworld of the city. The writer whose work The New York Times describes as "having the sweep and consequence of epic story telling" has outdone himself in this multi-layered and masterful suspense story. His latest book in the series, Strange Shores, was nominated for the 2014 Crime Writers of America Gold Dagger Award.
