a train heading toward them. They divert the train by building a device to remotely activate the railroad switch. Mr. Poe arrives and takes them away, thinking that Olaf was allowing Sunny to drive. The orphans are taken to their uncle, Dr. Montgomery Montgomery, an eccentric but kind herpetologist, but Olaf arrives disguised as his assistant "Stephano". The orphans attempt to warn Monty, but he believes he is after the Incredibly Deadly Viper, a giant misnomer python, in his laboratory. Monty is discovered dead shortly after, his death blamed on the viper. They are almost placed in Stephano's care by Mr. Poe, but Sunny proves his guilt by showing the snake is harmless and he escapes. Mr. Poe leaves them with their Aunt Josephine, a grammar-obsessed widow with panphobia. Olaf appears, disguised as a sea captain named "Captain Sham", to meddle with their plans again. One day, Josephine is not at the house, leaving an apparent suicide note entrusting them to Captain Sham. Klaus deduces that Olaf forced her to forge the note, but she left a hidden message revealing her location. They sail to the cave where she is hiding and rescue her, but attract leeches. Olaf appears and takes the children, leaving Josephine to be eaten by the leeches. Mr. Poe finds him with the children, and Olaf pretends to have rescued them. Mr. Poe is fooled and gives the children back to him. Olaf plans a play titled "The Marvelous Marriage", starring Violet and him as a bride and groom. Klaus's suspicions reveal that he is planning to take advantage of the play to really marry Violet in an attempt to get the fortune, using legally recognized vows and a bona fide justice of the peace. He locks Sunny up in a birdcage, threatening to drop her to her death if Violet refuses to take part in the play. Klaus escapes and finds a hidden tower in Olaf's house, where he discovers a large window with a set of lenses that, if positioned correctly, can focus the rays of the sun. He realizes that Olaf used it to set fire to the Baudelaire mansion. Using the window, Klaus manages to burn the marriage certificate, leading to Olaf's arrest, but he escapes later on. Violet, Klaus, and Sunny are taken to visit the charred remains of their old home one last time. A lost letter from their parents
