In San Agustin de Tango, you can never be sure what's waiting around the corner. Over the course of a single day - the day before today - the hero of this novel and his adored wife embark on a journey through the absurd and the surreal, encountering a choir of monkeys and a carnivorous ostrich, travelling from the studio of an artist obsessed with the colour green to the waistcoat pocket of a pot-bellied man. All the while, the tolling of the bell in the city square pushes their whirlwind adventure towards its fateful conclusion.
