Clarke arrived in Florida at the end of April. The short story, "The Man Who Ploughed the Sea", included in the "Tales from the White Hart" (1957) collection, was influenced by his time in Florida. While in Key Largo in late May, Clarke met Marilyn Mayfield, and after a romance lasting less than three weeks, they travelled to Manhattan and married at New York City Hall. The couple spent their honeymoon in the Pocono Mountains in Pennsylvania, where Clarke proofread "Childhood's End". In July, Clarke returned to England with Mayfield, but it quickly became clear that the marriage would not last as Clarke spent most of his time reading and writing, and talking about his work. Further, Clarke wanted to be a father, and Marilyn, who had a son from a previous marriage, informed Clarke after their marriage that she could no longer have children. When "Childhood's End" was published the following month, it appeared with a dedication: "To Marilyn, For letting me read the proofs on our honeymoon." The couple separated after a few months together, but remained married for the next decade.
