King employs a first person narrator and opens with the protagonist, Stan Norris, in the clutches of Cressner, a wealthy, cruel criminal overlord. Cressner intends to get revenge on Norris, who has been having an affair with his wife. Instead of killing him outright, Cressner reveals his penchant for striking wagers, and offers a chilling if Norris is able to circumnavigate the 5-inch ledge surrounding the multi-story building where Cressner live in his penthouse, he can have his wife and $20,000. If Norris refuses, he'll be framed for heroin possession and never see his lover again. Cressner also reveals that he has done this to six others, three professional athletes who crossed his path and three ordinary people who got into serious debt with Cressner. Not once has Cressner lost the wager. Seemingly without any other choice, Norris accepts the wager and proceeds to make his way carefully around the building's cold, windswept exterior. Norris encounters multiple obstacles, particularly from the wind and an obstinate pigeon. Norris completes the harrowing ordeal, only to discover that Cressner had already murdered his wife. Cressner slyly claims that he never welches on his bets and that, while the heroin has been removed from Norris' car and the money is his for the taking, his wife's fate was sealed before the wager was even made. Enraged, Norris overpowers Cressner's bodyguard and obtains his gun. When Cressner pleads for his life, Norris proposes to spare him if only he is able to complete a trip around the ledge. However, while waiting for Cressner to circumnavigate the building, Norris reveals to the reader that, unlike Cressner, he does sometimes welch on bets, implying that he will kill Cressner, regardless of his potential success on the ledge

Stephen Edwin King was born the second son of Donald and Nellie Ruth Pillsbury King. After his father left them when Stephen was two, he and his older brother, David, were raised by his mother. Parts of his childhood were spent in Fort Wayne, Indiana, where his father's family was at the time, and in Stratford, Connecticut. When Stephen was eleven, his mother brought her children back to Durham, Maine, for good. Her parents, Guy and Nellie Pillsbury, had become incapacitated with old age, and Ruth King was persuaded by her sisters to take over the physical care of them. Other family members provided a small house in Durham and financial support. After Stephen's grandparents passed away, Mrs. King found work in the kitchens of Pineland, a nearby residential facility for the mentally challenged. Stephen attended the grammar school in Durham and Lisbon Falls High School, graduating in 1966. From his sophomore year at the University of Maine at Orono, he wrote a weekly column for the school newspaper, THE MAINE CAMPUS. He was also active in student politics, serving as a member of the Student Senate. He came to support the anti-war movement on the Orono campus, arriving at his stance from a conservative view that the war in Vietnam was unconstitutional. He graduated in 1970, with a B.A. in English and qualified to teach on the high school level. A draft board examination immediately post-graduation found him 4-F on grounds of high blood pressure, limited vision, flat feet, and punctured eardrums. He met Tabitha Spruce in the stacks of the Fogler Library at the University, where they both worked as students; they married in January of 1971. As Stephen was unable to find placement as a teacher immediately, the Kings lived on his earnings as a laborer at an industrial laundry, and her student loan and savings, with an occasional boost from a short story sale to men's magazines. Stephen made his first professional short story sale ("The Glass Floor") to Startling Mystery Stories in 1967. Throughout the early years of his marriage, he continued to sell stories to men's magazines. Many were gathered into the Night Shift collection or appeared in other anthologies. In the fall of 1971, Stephen began teaching English at Hampden Academy, the public high school in Hampden, Maine. Writing in the evenings and on the weekends, he continued to produce short stories and to work on novels.
