Ice skating star Dorothy Hamill should have read the fine print on her insurance policy. She and her former husband, actor-tennis player Dean Paul Martin, were not successful in getting a federal appeals court to order Lloyd's of London to pay off for a theft of $365,000 worth of insured jewelry taken from their San Francisco hotel room in 1982.

Yesterday, Curtis received his rejection notice for his manuscript and was ordered to return the $50,000 advance. Doubleday described it as "junk, pure and simple" . . .
