They retired and regrouped their forces.

“Foolproof machines,” Ross said slowly. “And I mean really fool proof. Friends, I was wrong, I admit it; I thought that those buildings and cars were something super-special, and they turned out to be just silly gimcracks. But not this blue light thing. That boom had to fall.”

Bernie shrugged rebelliously. “So what? So they’ve got some kinds of machines you don’t have on Halsey’s Planet?”

“A different order of machines, Bernie! Believe me, that blue light was something as far from any safety device I ever heard of as the starships are from oxcarts. When we find the people who designed them——”

“Suppose they’re all dead?”

Ross winced. He said determinedly, “We’ll find them.” They returned to their begging and were recognized one day by the gray-haired profile of the party. He didn’t remember just who they were or where they were from or where he had met them, but he enthusiastically invited them to yet another party. He told them he was Hennery Matson, owner of an airline.

Ross asked about accidents and blue lights. Matson jovially said some o’ his pilots talked about them things but he din’t bother his head none. Ya get these planes from the field, see, an’ they got all kinds of gadgets on them. Come on to the party!

They went, because Hennery promised them another guest—Sanford Eisner, who was a wealthy aircraft manufacturer. But he din’t bother his head none either; them rockets was hard to make, you had to feed the patterns, like, into the master jigs just so, and, boy!, if you got ’em in backwards it was a mess. Wheredja get the patterns? Look, mister, we always had the patterns, an’ don’t spoil the party, will ya?

The party was a smasher. They all woke with headaches on Matson’s deep living room rug.

“You did fine, Ross,” Helena softly assured him. “Nobody would have guessed you were any smarter than anybody else here. There wasn’t a bit of trouble.”
