The Baudelaire orphans need a safe place to stay — somewhere far away from terrible villains and local police; a quiet refuge where they can find shelter and food, and have a chance to try and unravel the mystery that surrounds them.
Given the situation, a nearby hospital will have to do. If things go well, Violet may be able to use her inventing skills to enjoy the various fascinating equipment found at a hospital. And perhaps Klaus, who enjoys reading a great deal, will come across a piece of information in a library that could change the lives of the Baudelaires forever. And though hospitals are already full of dangerous sharp objects, Sunny's four extraordinary teeth may also come in handy.
Indeed, the hospital may be the safest place the Baudelaires can get to for now. And once they are there, they can only hope that their stay at Heimlich Hospital doesn't prove to be the nastiest in a series of unfortunate events.
