Six days later, a mushroom picker finds him in a meadow dead. Sis nits d'agost is the story of a beloved, unique and mysterious death. It talks about the revelation of how he prepared carefully for his death and how it affected so many people. And it explains the adventure of a writer to find out the ultimate meaning of an action like this to find answers about herself.
