The tenth book in this outrageous publishing effort features more than the usual dose of distressing details, such as snow gnats, an organised troupe of youngsters, an evil villain with a dastardly plan, a secret headquarters and some dangerous antics you should not try at home. With the weather turning colder, this is one chilling book you would be better off without. (From Amazon)
The title of this book refers not only to the mountain the Baudelaire children find themselves on but also to the slippery slope that could lead them to become villains. The Baudelaires are challenged to save their sister and find out the secrets of VFD without comprising their principles.
The performance of Tim Curry (who reads the story) is flawless - to the point where I forget who I'm listening to. His portrayal of Count Olaf is deliciously evil.
