ROSARIO AMES, the Colombian-born wife of Aldrich Ames, claimed she was surprised when she learned he was a spy for the Soviets. But she was afraid to turn him in, she said, fearful for their young son. Mrs. Ames failed to mention the fancy lifestyle her husband's treason bought her -- the big house and the humongous charge-card bills. Ames is doing life in prison. Last week, Rosario Ames got her penalty: 63 months behind bars. That's the least she could have gotten under a plea bargain struck last April when she admitted committing espionage and evading taxes.
