Laughter in the Dark - Nabokov, Vladimir

Albinus - rich, married middle-aged and respectable - is an art critic and aspiring filmmaker who lusts after the coquettish young cinema usherette Margot. Gradually he seduces her and convinces himself he is irresistible to her, but Margot has other plans. She wants to be a film star, and when Albinus introduces her to the American movie producer Axel Rex, she sees her chance - and plotting, duplicity and tragedy ensue.
