The living room of the quarters assigned to Dr. Benjamin B. Lowry on Cleaver Spaceport's security island was large and almost luxuriously furnished. In pronounced contrast to the adjoining office and work-rooms, it was also as a rule in a state of comfortable disorder. An affinity appeared to exist between the complex and the man who had occupied it for the past two years. Dr. Lowry, leading authority in the rather new field of diex energy, was a large man of careless and comfortable, if not downright slovenly personal habits, while a fiendish precisionist at work. He was slumped now in an armchair on the end of his spine, fingering his lower lip and staring moodily at the viewphone field which formed a pale-yellow rectangle across the living room's entire south wall, projecting a few inches out into the room. Now and then, his gaze shifted to a narrow, three-foot-long case of polished hardwood on the table beside him. When the phone field turned clear white, Dr. Lowry shoved a pair of rimless glasses back over his nose and sat up expectantly. Then he frowned. "Now look here, Weldon--!" he began.

He nodded, said in a briskly amiable manner, "Dr. Lowry, I received your message just a minute ago. As Colonel Weldon undoubtedly has informed you, I asked him to be present during this discussion. There are certain things to be told you, and the arrangement will save time all around. "Now, doctor, as I understand it, the situation is this. Your work on the project has advanced satisfactorily up to what has been designated as the Fourth Stage. That is correct, isn't it?" Dr. Lowry said stiffly, "That is correct, sir. Without the use of a trained telepath it is unlikely that further significant advances can be made. Colonel Weldon, however, has seen fit now to introduce certain new and astonishing conditions. I find these completely unacceptable as they stand and...."
