The purpose, the illusion, the spirit of a waxworks. It is walled off by stone grottos, like a dream, from the light of day... There's no denying the disquiet in the Musee Augustin - even the proprietor is perturbed by the apparent vitality of his waxworks. Only the bravest pay a visit, among them Inspector Bencolin, who is investigating the death of woman found floating in the Seine - and last seen alive entering the waxworks museum. A literary puzzle from the author of "Castle Skull" and "It Walks By Night".
