 Vanessa Vale, a glamor model, apparently jumps from the balcony of her 15th-story apartment to her death. But Mac investigates and finds signs of a struggle -- she was pushed off. Then Vanessa herself walks into the apartment, having gone incognito on a brief vacation. The victim, it turned out, was a lady friend of hers who was using the apartment; nobody thought to look under the makeup mask she had on her face when she was killed. Was the killer after Vanessa (it looks that way when her private plane, on which Mac is riding, is rigged to go into a tailspin) -- or was Vanessa hiding something?
