In a way, it felt good because it overshadowed the dark fear that still throbbed in his body. But something else was gone, too. The opportunity for him and his science club friends to investigate the properties of the altered metal was over.

Deputy Atkins appeared to be in charge of the group. Ken hailed him. "I want to go along, Mr. Atkins. May I go?" The deputy glanced down at him and frowned. He consulted a sheet of paper he drew
