Austin gingerly picked up the napkin as if it would fall apart. “This is the frequency that can neutralize a polar shift?”

Barrett's Adam's apple bobbed a couple of times “Hell, I hope so,” he said.

Karla leaned over and kissed Barrett on the top of his bald head. “You've done it.”

Barrett looked downhearted for someone who had saved the world. “Maybe. I'm afraid we don't have much time.”

“What do you mean?” Austin said.

“After our meeting, I listened to the phone conversations transmitted by the electronic bug you planted on Gant's estate. He and Margrave talked. They've left the country by now.”

“Damn,” Austin said. “Where did they go?”

“I don't know. Margrave never got around to telling me the plans for the final phase. But it's not where I'm worried about, but what. I think they're about to put their plans for a polar reversal into effect.”

“Any estimate on how long we have?”

“Hard to tell,” Barrett said. “The target location is in the South Atlantic. I wasn't in on the final discussions, so I don't know the exact spot. Once they're on-site, it's only a matter of hours before they pull the switch.”

Austin handed the napkin back to Barrett. “Can this equation be translated into something we can use to actually neutralize the reversal?”

“Sure. The same way E = mc2 was translated into the Bomb and nuclear power. All you need are the resources and the time.”

“You'll get all the resources you need. How long will you need to build something that will do the job?”

“I'll need help. I provided the engineering and made the scale model for the trigger device, but others worked on the actual construction.”

“I'll get you help. How long?”

Barrett gave him a bleak smile. “Seventy-two hours. Maybe.”

“I think I heard you say thirty-six,” Austin said. “How big will this device be?”

“Really big,” Barrett said. “You saw the setup on the transmitter ship.”

“Ouch,” Austin said. His unshakable confidence wavered for a second, but his agile mind was already cranking into gear. “What do you do with this thing once you get it built?”

“It has to transmit electromagnetic waves covering roughly the same area as the polar shift.” He shook his head. “We're going to have to figure out how to transport the neutralizer to the target area. Damn. I feel so responsible for this whole mess.”

Despite Barrett's biker appearance, he had a fragile psyche. Austin saw that guilt was tearing the brilliant computer whiz apart, and if that happened he would be of no use.

“Then I can't think of anyone who would be better at cleaning it up. Leave the transportation to me. I've got an idea that might work.”

He rose from his chair and put some bills down on the table for the beers. As they left the tavern, Austin saw Spider head toward his motorcycle and said, “Where are you going?”

“To ride my bike.”
