The discovery of a nuclear lab in suburban England prompts Harry to activate a long-quiet sleeper agent, a university professor who must sacrifice, albeit temporarily, his name and maybe even his family to trick terrorists into thinking he's created red mercury, a highly efficient chemical detonator.
