The Book of Illusions

The protagonist loses his wife and children in a plane crash.
To escape despair, he writes the biography of a silent-film actor who had vanished without a trace.
Tracked down by Alma, with whom he falls in love, he learns that the former actor lives on a farm, where he has continued to make films that he has resolved to destroy upon his death.
The protagonist reaches the country house to witness the former actor's death, manages to watch one of the films that had been produced, and then stands by as a spectator to the fire that destroys the entirety of the cinematic works.
The narrative concludes tragically with Alma’s death.
It is a complex novel, in many respects intellectualized and erudite, unfolding through paradoxical events around two philosophical and existential themes: the world is entirely an illusion, where the boundary between what is real and what is fiction or the product of our imagination remains blurred; and destruction—death—is the arbitrary outcome of the illusion in which we live.
The theme of illusion is personified by the former actor Hector: his origins are unknown, and he does everything to keep them obscure; he leads a double life in love that ends tragically; he is perpetually on the run, pretending to be someone else and fabricating situations until finally secluding himself in the countryside to produce cryptic films destined never to be shown in theaters.
The theme of destruction, of tragedies overwhelming human lives, of inexplicable events, is embodied in the very plot of the book and in the protagonist's torments.

The book is very well written, in a pleasant and fluid style.
Yet there is an intellectualist undercurrent that frequently renders the narrative pace cumbersome and redundant.
