Black novel with Argentines

New York City. Three A.M. The present. A man emerges from a building, a revolver in his pocket. Upstairs, in her apartment, alone in her bed, lies a woman - an actress the man met for the first time earlier that evening. She is dead. There is no motive, no history. All there is to know is that the paths of two strangers crossed one random night, and only one has emerged alive.
