Written in 1983, The Foreigner tells the story of Charlie Baker, a painfully shy fellow from England who has come to a remote town in rural Georgia for some R&R. His wife (whose indifference to him has been marked by a prodigious number of affairs with other men) is dying; he despairs of losing her and also that he does not seem to have a personality. His friend Froggy LeSueur, a British military man on assignment in America, has found him this restful spot and, to ensure that no one bothers him, has told the proprietress Betty Meeks that Charlie is a foreigner and neither speaks nor understands a word of English.
Betty, a cheery if not-too-bright elderly lady, is thrilled at the prospect of having a gen-u-wine foreigner at her inn, and quickly takes to the quiet young fellow. Soon, she's convinced that she and Charlie have developed a special way of communicating with one another (she's positive that she taught him his first words of English, "Thank You," his reflexive response to a proffered cup of coffee). The lodge's other residents--Catherine Simms, a pretty young heiress who is engaged to a patient, smooth-talking reverend named David Marshall Lee, and her somewhat dull-witted brother, Ellard--join the Charlie bandwagon, too. "You're such a good listener," Catherine tells the silent Charlie; Ellard, who will lose his share of the family inheritance unless he proves to Catherine that he's intelligent, finds that he is able to rapidly "teach" Charlie how to talk and read, with the latter "mastering" Shakespeare within hours.
As for Charlie himself, the new persona fits better than he ever imagined. He finds himself developing that elusive personality, as he learns his new made-up tongue, falls in love with Catherine, and devises a heroic plan to save her, Betty, and Ellard from the Ku Klux Klan. Sure, it's a little improbable, but it's great fun and also very sweet.
