Laure Mondo's specialty is the perfect crime. A successful novelist, perched on dizzying heels, Laure cultivates her mystery and deadly humor. The complete opposite of his assistant: Pica. Messy hair, loud laughter, colorful t-shirts, she is struggling to satisfy her whimsical boss. This mismatched duo will, however, be confronted with their first investigation: Yves Cayatte, boss of an international luxury group, is found dead in the swimming pool of his sumptuous Corsican villa. The police conclude it was an accident. But Laure doesn't believe it.
