Giverny. During the day, tourists flock to the former home of the famous artist Claude Monet and the gardens where he painted his Water Lilies. But when silence returns, there is a darker side to the peaceful French village. This is the story of thirteen days that begin with one murder and end with another. Jerome Morval, a man whose passion for art was matched only by his passion for women, has been found dead in the stream that runs through the gardens. In his pocket is a postcard of Monet's Water Lilies with the words: Eleven years old. Happy Birthday. Entangled in the mystery are three women: a young painting prodigy, the seductive schoolteacher and an old widow who watches over the village from a mill by the stream. All three of them share a secret. But what do they know about the discovery of Jerome Morval's corpse? And what is the connection to the mysterious, rumoured painting of Black Water Lilies?
