A minute later the two cars headed southeast into the night.

When the cat's away, the ancient adage ran through Taurus Haven's mind, the mice will play.

The cat being Prefect Galway, of course. It was now just five days since the hidden 'port spotters had seen Galway sneak aboard a Ryqril Corsair and disappear into the sky. Bound for Earth, presumably, and certain to arrive before the Novak. If the collies there opted for the heavy-handed approach...

Haven put the thought firmly from his mind. The best way to help Lathe now, he knew, was to do his job properly. And to make sure the rest of the mice did theirs.

The other mice being Capstone's unemployed and increasingly frustrated youth... and Haven had to admit that this little mob scene Dayle Greene had set up was the finest peaceful demonstration Plinry had ever seen. The crowd gathered around the Hub's floodlit east gate numbered at least six hundred, perhaps one in ten holding a sign or lighted torch against the black of night. They were being quiet, for the most part, listening as their spokesman brandished their list of grievances and called on the guards lined up inside the mesh gate to come out and accept the paper.

None of the Security men had taken him up on the challenge. Nor, Haven thought as he studied the half-hidden faces behind the mesh, did any of them look as if they intended to.

His tingler came on: Hammerschmidt approaching in car. Haven grinned tightly and began working his way unobtrusively toward the front of the crowd. They'd read Hammerschmidt correctly, all right, down to the last decimal. Galway would never do anything so stupid as coming out of the Hub to face down a mob, but his second-in-command had always had more idiot pride than was good for him. Hammerschmidt would come out, all right; with luck he'd at least have enough brains to bring a carload of troops out with him.

The assistant prefect's car arrived at the gate a minute later, and a short but animated argument seemed to take place between Hammerschmidt and the guard captain. The captain apparently lost, and Hammerschmidt's driver maneuvered the car to point at the center of the gate. The mesh slid open just enough to pass the vehicle, closed immediately behind it. Capstone's Security men had had a mob get past the wall once before and were clearly not interested in repeating the experience.

The crowd seemed to shiver like a thing alive as the car rolled toward it. Easy, Haven cautioned.

Don't spook them. But the crowd's leaders had been carefully coached, and no one moved as the vehicle came to a halt a few meters from the crowd's edge. The back doors opened and Hammerschmidt and a laser-armed Security man stepped out, the latter gripping his weapon tightly.

"All right," Hammerschmidt bellowed. "What the hell do you slime think you're doing?"

He was answered by the deep-throated twang of a large catapult a block south. All Security eyes jerked toward the sound, just in time to see a load of loose garbage arc neatly over the wall into the Hub. Trash-throwing had become a popular pastime among Capstone's youth in the past few days, a deliberate thumb in Security's eye. And from Hammerschmidt's expression, it looked as though he'd about had enough of it. "Over there!" he'd snapped, pointing south as he scrambled back into the car.

The other man joined him and the driver started to swing around—

And the crowd surged forward. An instant later the car was surrounded by a solid wall of shouting people.

The buildings around them lit up with flickers of light, and screams of pain mixed with those of anger as the gate guards opened up with their lasers. Set at low power, Haven hoped, but he had no time to worry about it. He was in position now, directly behind two of the blackcollars' trainees, who were pounding flat-palmed on Hammerschmidt's window and screaming at the top of their lungs. A

better distraction Haven couldn't have asked for. Ducking down, he wove through the gap the trainees had formed between their legs and slid onto his back under the car.

It was a cramped fit, but Haven had practiced on mock-ups at the lodge and his motions were quick and sure. Pulling the quick-release package on his belt, he spilled onto the pavement six "question marks"—fifteen-centimeter hooks with thermite self-welding connectors at the ends. He grabbed two, tore off the safety covers, and touched them firmly to the car's frame about shoulder width apart. There was a sharp hiss as the primer ignited, and abruptly the narrow space under the car flickered with blue-white light. Haven held the hooks steady for the three or four seconds it took for the fire to burn down. Then, scooping up two more, he wiggled down toward the rear of the car and implanted them a meter behind the first set. The screams of the burn victims were getting louder, he noted uneasily, and through the pavement he could feel the pounding of feet as the crowd peeled itself open before the laser beams. If the car was freed too soon...

The flames died and Haven moved forward again, stripping the last two question marks and jamming them into the outer parts of the frame. The running feet had become a stampede now, and looking toward the gate he could see occasional glimpses of the wall as his human screen melted away into the darkness.

The last two question marks burned out. They would need another few seconds to solidify properly, but Haven couldn't afford to wait. Hiking up on his elbows, he eased his upper arms snugly into the first set of hooks. His legs went into the second set; and even as he grabbed the third set with his hands the car jerked into motion, swerving around toward the gate. Gritting his teeth, Haven pressed against the frame, hoping to hell the bodywork overhang and shadow would give him adequate concealment.

The car darted through the gate and skidded to a halt, jamming Haven's arms painfully against their supports. For a moment Hammerschmidt and the captain conversed—Hammerschmidt's voice was too muffled for Haven to understand, but he sounded furious—and then the car was in motion again, heading through the largely residential outer parts of the Hub toward the official buildings near the center. For another kilometer or two there would be virtually no other traffic, which meant that here was where Haven had to get off.

He had his opportunity at the next corner as the car stopped to let some cross traffic pass. He wriggled out of the hooks and eased slightly to the side where he would be safe from both wheels and the rear set of question marks. Flattening himself against the pavement, he mentally crossed his fingers... and the car drove off, leaving him lying safely in the middle of the road.

Fortunately, no one else was coming; equally fortunately, Hammerschmidt's driver apparently wasn't watching his mirrors. Haven lay motionless until the car had cleared another block, then sprinted for the cover of the nearest building. There he took a moment to orient himself and listen for signs he'd been observed. Keeping to shadows as much as possible, he headed down the empty streets back toward the wall.

The distant twang of another catapult shot and the nearer splock of newly arrived garbage came right on schedule and gave him his final bearings. The trash had made it two full blocks inside the wall—the trash, and the tightly wrapped backpack that had gone over with it. Stepping carefully, Haven retrieved the heavy bundle, stripping off the filthy covering and settling the pack onto his shoulders as he faded back into the shadows. Faint cries reached his ears from distant parts of the wall—the multiple demonstrations that should, for the next hour, hold Security's attention outward.

He had just that long to reach his objective.
