Lemony Snicket's A Series of Unfortunate Events: The Reptile Room

The Baudelaires are sent to live with their herpetologist uncle Montgomery Montgomery, who has recently come across a reptile he calls the Incredibly Deadly Viper, a misnomer since the reptile is harmless and friendly. While attempting to learn more about Montgomery, Klaus discovers that the hedge maze in Montgomery's garden is exactly the same shape as the tattoo on Olaf's ankle. Olaf poses as Montgomery's new assistant Stephano and attempts to kidnap the Baudelaires, but Monty assures the Baudelaires that he recognizes Stephano as a threat.
