Cliffhaven--Magnificent new resort near Big Sur. Surrounded by redwoods. Guarded by oceanside cliffs. Protected from prying eyes. By reservation only. Cliffhaven--Founded by a man with very special interests, catering to a very special clientele. Margaret and Henry Brown, vacationing New Yorkers innocently driving down the sea-washed coast of California, are just the right sort of people. Cliffhaven--It has a spectacular entrance, a three-star restaurant, lavish accommodations--and no exit!
