The authorities in Mexico are searching for a man who claimed for more than ten years to be the sole confidante of one of the country's most respected writers, Nellie Campobello.

The missing man, Claudio Fuentes, said he was the only person the writer, notoriously reclusive, would talk to.

But now, the Mexican authorities say they've now found Nellie Campobello's body in a rural graveyard, as well as a death certificate saying she died twelve years ago at the age of eighty-six.

Claudio Fuentes -- and the writer's valuable collection of Mexican art treaures -- have vanished, and the attorney-general in Mexico City has issued a warrant for his arrest.
