“At the outset, Nair is in Sierra Leone to keep tabs on his old friend and uses the occasion to practice a little freelance extortion, stealing unspecified multinational secrets on a flash drive and sending them back to his girlfriend in Amsterdam. The first 50 pages are like a Johnsonian take on Graham Greene’s humid morality-play potboilers. Nair keeps meeting shifty European acquaintances and distrusting everything they say.” John Lingan reviews Denis Johnson’s new novel.
