Death in the Andes, by Mario Vargas Llosa (Faber & Faber, £6.99 in UK)

"You have to be pretty dumb to join the Civil Guard

"You have to be pretty dumb to join the Civil Guard. The pay is lousy, nobody can stand you, and you're the first one they blow up with dynamite . . ." So says Civil Guard Corporal Lituma, who, with his sidekick Tomas Carreno, has been despatched to a remote Andean village to investigate the disappearance of three men. This being Peru, however, the "investigation" takes a somewhat unorthodox direction. Structured like a thriller, this modestly-sized novel packs a huge punch - without losing his grip for a second, Vargas Llosa weaves into his story a beautifully-judged helping of magic realism, some truly scarifying terrorism, a marvellously naive love story and a lot of disgruntled observation, most of it from the mouth of Lituma, a brilliantly understated creation, half-cynic, half-Good Samaritan.
