The literary agency of Juan Marsé says the Spanish novelist has died. He was 87, Associated Press reports.

The Carmen Balcells agency announced his passing on Sunday. It did not give a reason for his death.

Marsé was one of Spain’s most-respected novelists over the past few decades and the winner of the 2008 Cervantes Prize, the Spanish-speaking world’s top literary award.

Marsé’s most important novel was “Úlitmas tardes on Teresa” (“Last Afternoons with Teresa”) published in 1965. It chronicles the misadventure of a working-class adolescent who tries to win over a girl from the upscale side of Barcelona.
