The Reptile Room is a children's novel and the second of A Series of Unfortunate Events by Lemony Snicket. Having just escaped from the greedy and evil Count Olaf in the first book, the Baudelaire children are now taken to live with another relative, Dr. Montgomery. While the children find Dr. Montgomery to be a kind herpetologist, Count Olaf's final threat in the previous book continues to throw a shadow over their future.
