For three decades Clancy wrote hundreds of best-selling spy novels, and this estate, a former summer camp for children, was created to resemble the fictional estate belonging to Jack Ryan, one of the characters in his books. Called Peregrine Cliff, it has an underground gun range, tennis courts, a basketball court, an indoor pool with a retractable roof, a two-story entertainment pavilion, a three-bedroom guesthouse and one mile of waterfront.
