Used book – Bibliothèque rose: Fantomette: Fantomette and the Devil's Tooth, G. Chaulet

What strange events are happening in this chalet where Françoise, Ficelle, and Boulotte are spending their holidays! For no reason, the television and telephone break down, while all the batteries in the radios disappear. At night, strange noises are heard, and a chemical smell hangs in the air... Enough to send shivers down the spine of even the bravest. Isn't that right, Fantômette?
