3rd flower of algenon

 Doctors sit on a jet bound for the international psychological convention in Chicago. The stewardess' polite tried to strap Charlie's seat belt conjure memories of his childhood visits to the cheater Dr. Guarino. Promising to make young Charlie smart, Dr. Guarino strapped Charlie down under a blinking, humming machine. Terrified, Charlie wet his pants and mortified his mother. Matt Gordon objected to continued treatment with the phony doctor, preferring to use the money to get out of sales and to open his own barber shop. Even though Dr. Guarino took advantage of his parents, Charlie remembers Guarino as a kind and encouraging man. 

Newspapers take upon the emotional story of Charlie's flight from the convention. Charlie slip across a background article on his own family, accompanied by a jarring photograph of his mother and sister. The picture reminds Charlie of the night his frustrated mother decided to send him away to the Warren State Home for Norma's protection.

Charlie moves into a new apartment and meets his strange next-door neighbor, a free-spirited artist named Fay Lillman. Locked out of his apartment, Charlie hopes to use Fay's fire escape to access his own window. The flirtatious and half-naked painter invites him in and, surrounded by her mess, they quickly become friends. 

After a few drinks, Fay follows Charlie across the fire escape and back into his own orderly apartment. Fay discovers a three-dimensional plastic maze that Charlie constructed for Algernon's routine exercise. Charlie finds his nutty and lively neighbor very attractive.
