Nenúfares Negros (Black Water Lilies) by Cassegrain, Duval and Bussi

This is the Spanish translation. There is a digital translation to English by Europe Comics.

This is a gripping crime mystery graphic novel which is based on a novel of the same name by Michel Bussi. I loved the plot, and the twists. I loved the beautiful setting in a French village: Giverny, and the three mysterious female protagonists. And if that wasn't enough to like this book, there are, through out the whole novel, traces of Monet's art, in the landscapes and flowers that he painted and in some of the events in the story.
