“See here, Mr. Hebster,” Theseus said at last, “if you don’t want to buy Larry’s reductio ad absurdum exploder, and you don’t like my method of decorating bald heads for all its innate artistry, how about a system of musical notation—”

Somebody tried Hebster’s door, found it locked. There was a knock on the door, repeated almost immediately with more urgency.

“He’s already found something he wants,” S.S. Lusitania snapped. “Yes, Larry, that was the complete list.”

Hebster plucked a handful of hair from his already receding forehead. “Good! Now, look, I can give you everything but the two Empire State Buildings and the three Radio Cities.”

“Or the three Radio Cities,” Larry corrected. “Don’t try to cheat us! Two Empire State Buildings or three Radio Cities. Whichever is more convenient. Why… isn’t it worth that to you?”

“Open this door!” a bull-mad voice yelled. “Open this door in the name of United Mankind!”

“Miss Seidenheim, open the door,” Hebster said loudly and winked at his secretary, who rose, stretched and began a thoughtful, slow-motion study in the direction of the locked panel. There was a crash as of a pair of shoulders being thrown against it. Hebster knew that his office door could withstand a medium-sized tank. But there was a limit even to delay when it came to fooling around with the UM Special Investigating Commission. Those boys knew their Primeys and their Primey-dealers; they were empowered to shoot first and ask questions afterwards—as the questions occurred to them.

“It’s not a matter of whether it’s worth my while,” Hebster told them rapidly as he shepherded them to the exit behind his desk. “For reasons I’m sure you aren’t interested in, I just can’t give away two Empire State Buildings and/or three Radio Cities with foundations intact—not at the moment. I’ll give you the rest of it, and—”

“Open this door or we start blasting it down!”

“Please, gentlemen, please,” Greta Seidenheim told them sweetly. “You’ll kill a poor working girl who’s trying awfully hard to let you in. The lock’s stuck.” She fiddled with the door knob, watching Hebster with a trace of anxiety in her fine eyes.
