The Tea Party was a party held in Esmé Squalor's penthouse apartment where Beatrice Baudelaire met her for the first time. The earliest mention of this party was in the Hostile Hospital, where Lemony Snicket said that he could hop for joy if he stopped Beatrice from attending it. He also implied that if he did so, he could erase the unfortunate events of the Baudelaires, meaning that The Tea Party was the cause of it.
One Thursday, A V.F.D. agent was a baker who made the scones served at the party. His assistant had to smuggle the secret ingredient into the scone through a drain pipe. While this was happening, a crafty volunteer (possibly Beatrice or Esmé) wore a dress and jumped around in it, creating the illusion of a fire in the kitchen. During the tea party, Lemony Snicket stole the sugar bowl, but Esme thought it was Beatrice who did.
