Polly Next was born in 1920. She married Mycroft in 1938, and they had two children: Orville and Wilbur Next. She was just as intelligent as Mycroft, and became his assistant after the previous one, Owens, was killed by one of the inventions which formed a giant meringue around him, cutting off his air.
Unfortunately, neither of their sons inherited the intelligence that they shared, but their great-niece, Tuesday Next, did.
Polly appears in the following works:
- The Eyre Affair, Thursday Next series, volume 1
- Lost in a Good Book, Thursday Next series, volume 2
- First Among Sequels, Thursday Next series, volume 5
