In "The Portrait of a Gentleman," the narrator arrives in Seoul and, after a tiring journey from Peking, takes a walk through a bustling street filled with Koreans in traditional attire. He enters a secondhand bookshop and discovers a surprising find among religious texts: a book titled "The Complete Poker Player" by John Blackbridge. Intrigued, he purchases the book for a small sum. The narrator imagines Blackbridge as a dignified, middleaged man with a keen intellect and a deep understanding of human nature, particularly in the context of poker. The book, filled with Blackbridge's aphorisms and insights, provides the narrator with unexpected entertainment and a vivid portrait of its author.
