One night, he meets a woman named Antoinette who seems to fit in perfectly, adapting her speech patterns to match any conversation partner.
Coretti follows Antoinette to various other bars and clubs, watching as she drinks and talks with a male companion; her appearance and clothing shift to let her fit in wherever she goes.
He follows them to a room in the hotel where he has been staying, but flees in horror upon finding a crowd of creatures just like them, who can live solely on alcohol and change their appearance and behavior to blend in at any bar they enter.
He takes a night job and finds lodgings at a boarding house, but after three weeks he receives a telephone call inviting him to join "the belonging kind."
