Hallam, for instance, pushes his investigation into the metal that has changed within the reagent bottle on his desk because he had said, when he discovered it, "That's not the tungsten," and his colleague across the hall, a more highly regarded young scientist named Benjamin Allan Denison, had challenged him with, "How would you know?" If Hallam had not been pushed, the plutonium might simply have become more radioactive until it exploded with catastrophic results. Later in Lamont's investigation, he discovers that official accounts credit Hallam with speculations about the origin of the plutonium although others had actually made the remarks. Hallam, however, headed the team to investigate the plutonium, and Hallam received the acclaim and the power.
