Rosaura A Las Diez by Marco Denevi

In a Buenos Aires boarding house, a timid, solitary painter becomes the focus of scandal and investigation when a mysterious young woman who claimed a connection to him is found dead; the story unfolds through police reports, witness testimonies and personal letters, gradually revealing conflicting versions of events, hidden passions and social hypocrisies until a surprising twist forces readers to question truth, guilt and the reliability of memory.
