Isadora Quagmire is one of the three Quagmire triplets. She, along with her brothers Duncan and Quigley, were orphaned after the Quagmire parents are killed in a fire. Caught in a similar plight to that of the Baudelaires, the Quagmires are heirs to a large fortune, which Count Olaf is determined to claim for himself. He kidnaps Duncan and Isadora at the end of The Austere Academy and keeps them in his clutches until the end of The Vile Village, where they escape with Hector in his Self-Sustaining Hot Air Mobile Home. Isadora is the family poet, who composes couplets to help assess the various dilemmas that the family finds itself in, or to assist in undermining one of Olaf's schemes.
