When journalist Kevin Burns gets a call from former schoolmate Carl Greene, he's surprised. They weren't that close at school and the temperature cooled even more when Carl married Kevin's girl, Lucy. Carl, a scientist, sounds anxious and afraid. They arrange to meet at a baseball game in Denver but Carl never makes it. Someone kills him first. Soon after, Lucy surprises a masked figure prowling Carl's study. Whatever her husband was working on, a lot of people want to get their hands on it. Some are clearly prepared to kill for it, though not the prowler from the critically acclaimed author of Easy Money, Iced and Flashback.
