Carolina Garcia-Aguilera: Bloody Shame (USA 1998)
From the Publisher:
Cuban-born PI Lupe Solano is coerced by an old friend and sometime lover, criminal defense attorney Tommy McDonald, to investigate what appears to be an open-and-shut case of self-defense. A prosperous Cuban-American merchant claims he shot a Cuban rafter when the man attempted to rob his shop. At the same time, Lupe's closest friend, Margarita, dies in a car accident on her way to reveal important information to Lupe. Are the two events related? Lupe has a hunch they are.
