now—get inside it!" They went forward in a pellmell rush. Kane eased open a back door of the car—a sedan with a lone man at the wheel—and all six of them squeezed themselves into the back seat, pulling the door quietly to after them. They held their breath, but there was no cry of surprise or alarm. The soldiers went routinely but thoroughly through the ritual of halberds. Any invisible man clinging to the outside of the vehicle would have had to drop off or be dragged into the wicked blades. The car rolled through the gate and picked up speed with the violent surge of an electric motor. The man hunched in the front seat drove with businesslike concentration, oblivious of his six unwanted passengers. The raiders grinned at each other, shifted their cramped positions a little and waited. Presently the town's lights began to swim past. Kane, in a position to see out the left-hand window, muttered: "We're passing the rocket field—they've thrown a brand-new wall around it. If this guy would just slow down—well, we've got to stop the car." He wriggled up until he could lean over the front seat—and stiffened. All of them heard the moan of a siren closing up behind. "Donnerwetter!" growled their chauffeur, and clamped on the brakes. A few feet behind loomed up a pair of headlights and a searchlight helped bathe the car ahead in a merciless illumination. "Out!" said Kane sharply, flinging open the left-hand door. They sprawled out and ran, stooping instinctively, through the patch of brilliance. Uniformed Germans were climbing out of the other vehicle and starting to form a cordon. Dugan, the last man out, halted a moment to close the car door, then sprinted after the rest. They huddled against the forbidding wall that had been built around the rocket port. Larrabie, eyes on the brightlit scene, nervously hefted a bomb. Kane shook his head. "Time enough to make big noises when we get inside," he advised. And to the whole party, "I spotted an entrance a couple of hundred yards back. Come on!" They ran in single file under the frowning face of concrete. It might have been possible to form a human chain and get over the wall; but there was unquestionably alarms atop it, and ready guns. Beyond the wall, a whistle began hooting. The field was being alerted.
