"I pretended the truck stalled and I couldn't start it. Two other drivers tipped off our men. We left those trucks and some others out on the field, so the drivers wouldn't be suspected of alerting us."

"Good work," said Bors. "Better put detectors on all parcels from all trucks before bringing them aboard."

"Booby-traps can be made very tricky indeed, but when they are used by secret police...." Bors allowed himself to rage for a moment only, at the idea of that kind of terrorism practiced by a government on its supposed citizens. It would be intended to enforce the totalitarian idea that what is not commanded for the ordinary citizen to do is forbidden to him. But secret-police booby-traps and time-bombs would be standardized. He hadn't allowed time for complex, detection-proof devices to be made. Detectors would pick out any ordinary trickery.

The harsh-voiced broadcaster continued to harangue the population of Tralee, of which the least of his words was high treason. They enjoyed the broadcast very much.

Presently Bors began to fidget. The Isis had been aground for thirty-five minutes. He had sat in the control room that whole time, supervising a smoothly-running operation. He had had to supervise it. Nobody else could have planned and carried it out. But it was not heroic. He had the line officer's inherent scorn for administrative officers, who are necessary but not glamorous or admired. He was stuck with just that kind of duty now. But he fretted. The local officials were given time to get over their panic. They ought to be planning some counter-measure by this time.

He called the spaceport office.

"There should be a map of the city somewhere about," he said crisply. "Send it along special. Bring a communicator call-book. If you find any news-reports, new or old, we want them."

"Yes, sir," said a brisk voice. "The broadcast's right, sir?"

"It is," said Bors. "You're mining the grid set-up. We'll blow it before we leave. There's no point in letting Mekin set down transports loaded with troops to punish innocent people because they heard the Mekinese accurately described. Make 'em land on rockets and there won't be so many landing."

"Yes, sir. Will do, sir."
