Book excerpt: Antonio Tabucchi describes his novella Indian Nocturne (winner of the Medicis Prize in its French translation) as 'an insomnia' but 'also a journey... in which a Shadow is sought.' In his provocatively elusive but totally compelling way, Tabucchi takes us along on a nightmarish trip through the Indian subcontinent, producing sensations by turns exotic, sensual, menacing, and oppressive, as the profound weight of an ancient culture settles on the unwary traveler.
