of a distorted mirror. “That could be our signal,” Rod said. “They’re using the mirror to flash—”
The glare became blinding, and all the screens on that side went dead.
The forward scanners were operative and recording. They showed a wide white disc, the star New Caledonia, very close, and approaching very fast, 6 percent of the velocity of light; and they showed it with most of the light filtered away.
For a moment they also showed several odd black silhouettes against that white background. Nobody noticed, in that terrible moment when MacArthur was burned blind; and in the next moment the images were gone.
Kevin Renner spoke into the stunned silence: “They didn’t have to shout,” he complained.
“Thank you, Mr. Renner,” Rod said icily. “Have you other, perhaps more concrete suggestions?”
MacArthur was moving in erratic jolts, but the light sail followed her perfectly. “Yes, sir,” Renner said. “We’d do well to leave focus of that mirror.”
“Damage control, Captain,” Cargill reported from his station aft. “We’re getting a lot of energy into the Field. Too much and damned fast, with none of it going anywhere. If it were concentrated it would burn holes in us, but the way it washes across, we can hold maybe ten minutes.”
“Captain, I’ll steer around behind the sail,” Renner said. “At least we’ve got sun-side scanners, and I can remember where the pod was—”
“Never mind that. Take us through the sail,” Rod ordered.
“But we don’t know—”
“That was an order, Mr. Renner. And you’re in a Navy ship.”
“Aye aye, sir.”
The Field was brick red and growing brighter; but red wasn’t dangerous. Not for a while.
As Renner worked the ship, Rod said casually, “You may be assuming the aliens are using unreasonably strong materials. Are you?”
“It’s a possibility, sir.” MacArthur jolted; she was committed now. Renner seemed to be bracing himself for a shock.
“But the stronger the materials are, Mr. Renner, the thinner they will spread them, so as to pick up the maximum amount of sunlight for the weight. If they have very strong thread they will weave it thin to get more square kilometers per kilo, right? Even if meteors later get a few square km of sail, well, they still made a profit, didn’t they? So they’ll make it just strong enough.”
“Yes, sir,” Renner sang. He was driving at four gees, keeping Cal directly astern; he was grinning like a thief, and he was no longer bracing himself for the crash.
Well, I convinced him , Rod thought; and braced himself for the crash.
The Langston Field was yellow with heat.
Then, suddenly, the sunward scanners showed black except for the green-hot edge of MacArthur ’s own Field, and a ragged blazing silhouette of white where MacArthur had ripped through the intruder’s sail.
“Hell, we never felt it!” Rod laughed. “Mr. Renner. How long before we impact the sun?”
“Forty-five minutes, sir. Unless we do something about it.”
“First things first, Mr. Renner. You keep us matched up with the sail, and right here.” Rod activated another circuit to reach the Gunnery Officer. “Crawford! Put some light on that sail and see if you can find the shroud connections. I want you to cut the pod off that parachute before they fire on us again!”
“Aye aye, sir.” Crawford seemed happy at the prospect. There were thirty-two shrouds in all: twenty-four around the edge of the circular fabric mirror and a ring of eight nearer the center. Conical distortions in the fabric told where they were. The back of the sail was black; it flashed to vapor under the pinpoint attack of the forward laser batteries.
Then the sail was loose, billowing and rippling as it floated toward MacArthur . Again the ship swept through, as if the light sail were so many square kilometers of tissue paper.
And the intruder’s pod was falling loose toward an F8 sun.
“Thirty-five minutes to impact,” Renner said
