"He's shortening the dispersion. He intends to cut the power by slamming more of the widespread beam into the receptor. The tighter beam makes aiming more difficult, you know, because at seventy million miles, every time little Joey on Mars swings his toy horseshoe magnet on the end of his string, the beam wabbles. And at seventy million miles, how much wabbling does it take to send a narrow beam clear off the target?"
"The normal dispersion of the beam from Venus is over a thousand miles wide. It gyrates and wabbles through most of that arc. That is why we picked that particular dispersion. If we could have pointed the thing like an arrow, we'd have kept the dispersion down."
"Right. And he's tightened the beam to less than a hundred miles' dispersion. Now, every time a sunspot gets hit amidships with a lady sunspot, the beam goes off on a tangent. We've lost the beam eleven times in a week. That's more times than I've lost it in three years!"
"O.K.," said Channing. "So what? Mastermind is responsible. We'll sit tight and wait for developments. In any display of abilities, we can spike Mr. Burbank. Have another drink?"
"Got any more? If you're out, I've got a couple of cases cached underneath the bed in my apartment."
"I've plenty," said Channing. "And I'll need plenty. I have exactly twenty-two hours left in which to produce something comparable to the telephone, the electric light, the airplane, or the expanding universe! Phooey. Pour me another, Arden."
A knock at the door; a feminine voice interrupted simultaneously. "May I come in?"
It was Walt's secretary. She looked worried. In one hand she waved another letter.
"Another communiqué?" asked Channing.
"Worse. Notice that for the last three hours, there have been less than twelve percent of messages relayed!"
