Lecky wetted his lips.
"I think," he said very carefully, "that you suspect it is a wave-type which will break any dynamic system, in any sort of object a dynamic system can exist in."
"Yeah," said the sergeant. He waited, looking at Lecky.
"And," said Lecky, "not only operating machines are dynamic systems. Living plants and animals are, too. So are men."
"That's what I'm drivin' at," said Sergeant Bellews.
"So you believe," said Lecky, very pale indeed, "that we have been given the circuit-diagram of a transmitter which will broadcast a wave-type which destroys dynamic systems—life as well as the operation of machines. Persons—in the future or an alien creature in a space-ship, or perhaps even the Compubs—are furnishing us with designs for transmitters of death, to be linked together so that if one fails the others will carry on. And they lure us to destroy ourselves by lying about who they are and what they propose."
"They're lyin'," said the sergeant. "They say they're in the future and they don't know a thing about Mahon units. Else they'd use 'em."
Lecky wetted his lips again.
"And—if they are not in the future, they are trying to get us to destroy ourselves because that would be safer and surer than trying to destroy us by—say—transmitters of death dropped upon us by parachute. Yet if we do not destroy ourselves, they will surely do that."
"If we don't bump ourselves off, it'll be because we got wise," acknowledged the sergeant. "If we get wise, we could bump them off by parachute-transmitter. So they'll beat us to it. They'll have to!"
