A Widow’s Game (La viuda negra)

"The story begins in August 2017, when the body of a man is discovered in a Valencia parking garage—stabbed seven times. Initially presumed a crime of passion, the case is assigned to the city’s homicide unit, led by a veteran inspector. But the investigation quickly takes a surprising turn, pointing to an unlikely suspect: Maje, the young and seemingly sweet widow, married to the victim for less than a year."
