"Very well," Braun said, "we'll wait." When the other had left the room, leaving the door open behind him, the doctor turned to his two younger associates. "What children we've been." Ross Wooley growled unhappily, "Brother, we couldn't have picked a worse so-called Common Man, if we'd tried. That character is as nutty as a stuffed date. Do you realize what he's in a position to do?" Patricia twisted her mouth thoughtfully. "I wonder if any of us really realize. I am afraid even with all our speculation, we never truly thought this out." Dr. Braun pushed his glasses back on his nose with a forefinger. He shook his head. "You make a mistake, Ross. We didn't make a bad choice in our selection of Don Crowley for our typical Common Man." Ross looked at him and snorted. Braun said doggedly, "Remember, we attempted to find the average man, the common man, the little man, the man in the street. Well, it becomes obvious to me that we did just that." Patricia said thoughtfully, "I don't know. I'm inclined to think that from the beginning you two have underestimated Don. He has certainly shown considerable ingenuity. Do you realize that he's done all this in a matter of less than a week?" "Done all _what_?" Ross said sarcastically. She gestured. "Look at this establishment. He's obviously acquired considerable money, and he already has an organization, or at least the beginnings of one." "That is beside the point," Braun said ruefully. "I say that he is reacting as would be expected. As the average man in the street would react given the opportunity to seize almost unlimited power, and with small chance of reprisal." Patricia shrugged as though in disagreement. Braun looked at Ross Wooley. "Close the door, Ross. Lord knows when we'll have another chance to confer. Obviously, something must be done." Ross came quickly to his feet, crossed to the door, looked up and down the hallway which was empty and then closed the door behind him. He came back to the others and drew his chair in closer so that they could communicate in low voices. Braun said, "One thing is definite. We must not allow him to secure further serum. For all we know, he might be planning to inject some of those gangsters he's affiliated himself with." Patricia shook her head thoughtfully. "I still think you underestimate Don. He must realize he can't trust them. At this stage, he has had to confide in at least two or three, fully to utilize his invisibility. But in the long run it isn't to his advantage to have _anybody_ know about it. If the authorities, such as the F.B.I., began looking for an invisible man, sooner or later they would penetrate the field of invisibility." "You mean you think Crowley will use these men for a time and then ... destroy them?" "He'll have to, or sooner or later the secret will be out." Braun said in soft logic, "If he can't allow anyone to know about it, then we, too, must be destroyed." Ross growled, "Then we've got to finish him first."
