To Hotel Denouement Fire (Possibly)
- "I'm so hungry I could eat a dekagram of rice."
- —Mrs. Bass in The Penultimate Peril
Her black hair was so long and messy that she vaguely resembled a gorilla. Mrs. Bass was a teacher obsessed with the metric system. Each day she made students measure anything she could find and had them call it out in class.
She thinks that Klaus is very smart and nice as she states so in The Austere Academy, when giving out hard tests to Violet and Klaus.
She returns in The Penultimate Peril at Hotel Denouement. She turns against the Baudelaires, accusing them of bank robbery. It is not clear if Mrs. Bass escapes the fire at the hotel, however, it is possible she did because in The Austere Academy, Lemony Snicket states that Prufrock Preparatory School closed after she was arrested for robbing Mr. Poe's bank. Some theorize she stole the Baudelaire Fortune as there is a pile of large bulky bags in her hotel room with PROPERTY OF MULCTUARY MONEY MANAGEMENT stamped on them.
