Some time ago, Earth Defense Directorate agents killed Morgan Deneva, a member of the deadly Legion of Death. These assassins have sworn revenge, and with their brains and unusual abilities, they might well manage it. So Buck goes undercover as Raphael Argus, a killer whom the Legion was on the cusp of inducting, but whose face is unfamiliar to them. His job is to infiltrate them and learn what they're planning. But they have a spy in the Directorate whose inside information might end Buck's imposture rather... abruptly...

Commander Corliss and Roxanne Trent lead a criminal organization holed up in the Necrosis asteroid belt. No one can reach them there because no one knows how to enter except them - and an old fighter pilot Wilma forced out of service for medical reasons. When Corliss steals a quantity of nerve gas slated for destruction, reaching him becomes essential. He plans to release the gas in Earth's atmosphere: revenge for his maiming during a narrow escape from Earth forces. Wilma must ask a man she recently described as inadequate for help.
