Silent Fury

NATIONAL BESTSELLER IN FRANCE.
THE SECRET OF FORTY YEARS OF AGED.
A respectable elderly woman emerges from the pool of an expensive resort. Suddenly, her eyes widen, and her nerves tighten like strings: she sees a man and recognizes him. The woman... watches as he returns to his bungalow. Then she runs to her room, grabs a large kitchen knife, and knocks on the man's door. And when he opens it, she lunges and begins to stab him wildly...
When she is arrested, she doesn't say a word. She doesn't answer a single question from the investigator. Complete silence... She even refuses to talk to her son Theo.
Knowing his mother, he understands that this burst of fury cannot be explained by a mistake or a lapse in judgment. Something else is going on... Theo learns that the victim of the attack is a well-known doctor from Switzerland. He travels to Lausanne but finds something completely unexpected. And this discovery will change his entire life...
