“Such a team has already been summoned to deal with the safety hazard on the roof of Government Tower.”

“There is no hazard on Government Tower,” Justen said. “It’s all been staged.” But even so-Justen thought for a moment. Even if the chemical spill had been manufactured, that did not mean it was not dangerous. It needed to be dealt with. But he would need people, robots, and equipment on the ground as well. “Redirect half the emergency team to the plaza. We’ll need crowd control and an arrest team or two.” If nothing else, maybe the police presence would disrupt whatever they had intended for the plaza.

Having done what he could about all that, Justen focused his attention back on the problem immediately at hand. He had to warn Lentrall. But how the devil could he contact Lentrall’s robot, when he didn’t even know the robot’s name, let alone its hyperwave contact code? The university. That was it. They would have a look-up list, for people who wanted to leave messages for the professors. He reached for the comm controls and got to work.

ROBOT CFL-001, BETTER known as Kaelor, was walking in his accustomed place, three steps behind his master, and having to move pretty briskly at that-even though Lentrall was going nowhere in particular. Everyone else might be willing to mill about, passively waiting for their aircars to be brought down, but Lentrall felt the need to be active. He kept walking back and forth around the plaza, trying to find the spot from which he could best see what was going on up on the roof.

As best Kaelor was able to judge, there was no spot on the ground from which anything could be seen, but that didn’t stop Lentrall from looking. There was nothing for it but for Kaelor to follow his master back and forth, up and down, doing his best to stay out of everyone’s way. He was dodging out of the way of a portly gentleman when the call came in.

A call in and of itself was by no means unusual, and Kaelor took it without breaking stride, or calling attention to himself. He spoke over the hyperwave link, without speaking out loud or making any outward sign. Nine times out of ten, Lentrall wasn’t interested in conversation anyway, and Kaelor simply took a message.

“Robot CFL-001 responding for Davlo Lentrall,” he said, his hyperwave voice not quite diffident enough to be rude. “Please go ahead.”

“This is Commander Justen Devray of the Combined Inferno Police,” a voice replied. “I have reason to believe your master is in immediate danger, within the next minute or two, either of assassination or of kidnapping. Protect him at once.”

“Message received. I am acting on it.” Kaelor might have been designed with a constricted First Law, but the constrictions were intended to help him deal with hypothetical, longterm danger better than most Inferno-built robots. There was nothing in the least constricted about his reaction in a case of actual and current danger to his own master. He started moving before Commander Devray had even finished speaking.

Without a word of explanation, Kaelor lunged forward and grabbed Davlo Lentrall, throwing both arms around Lentrall’s waist from the rear, and lifting him bodily off the ground.

“Kaelor! What are you doing? Have you lost your mind?”

Kaelor ignored his master’s protests. He had already spotted an ideal protective spot. Kaelor moved toward it, fast.

The Government Tower Plaza had a number of long, low benches scattered about, each bench carved from a single block of stone. The rear portion of each bench’s backrest was carved away, no doubt in order to form a pleasing curve. But it also meant the carved-out area below and behind the backrest had solid stone over it and in front of it.

Kaelor rushed for the nearest bench, swung Lentrall’s body around into a reclining position, and forced him to lie down behind the bench, with his back on the ground. With the reflexes of a Spacer who knows not to argue with a robot determined to obey the First Law, Lentrall gave up struggling and cooperated. Kaelor lay down in front of his master with his back to him, so that his eyes were facing out and he could. keep watch. Five seconds after the CIP commander had called him, he had his master lying flat on his back, shielded by a stone bench on one side and over him, and Kaelor’s own body serving as a shield for the other side.

“There is a threat against you, sir,” said the robot, before his master could ask any of the obvious questions. “The police just hyperwaved a warning to me a few seconds ago. They fear your assassination or kidnapping.”

“That’s absurd!” Lentrall said. “Who in the devil would want to attack me?”

“I do not know. Someone who does not like the idea of you dropping a comet on them, perhaps.”

For once, Davlo Lentrall had no reply. All he could do was wait and see what happened next.

Kaelor was fairly sure he would not have long to wait.

“THE BUS IS rolling!” the voice in Cinta’s ear announced, telling her something she could see with her own eyes. She watched the bus pull away from the curb and head toward the plaza, gradually gathering speed as it moved forward.

Most of the passengers aboard that bus were merely highly realistic dummies, some of them programmed to moan, cry out, and writhe about a bit, even spurt realistic blood. The four or five real people aboard the bus were in the best padded seats, ready with bladders full of simulated blood that would pop open on cue, and with ghastly-looking injuries that were testaments to the skills of the makeup artist. For the moment, the mock injuries were hidden beneath wigs and tear-away clothing. Once the bus had crashed, all would be revealed.

A nice job, all around-doubly so, given the rush nature of the assignment. It wouldn’t have been possible at all if the SSS Covert Office hadn’t had most of the gear and people available on standby. By all accounts, there were some very interesting things in the CO warehouse.

Cinta swung the magniviewers to see if she could spot Lentrall. Still no luck. Nothing to see but a crowd of people looking up toward the roof, waiting for their aircars to be shuttled down to them.

It was just as well she knew the lobby team and the plaza team were tracking him, or else-there was something wrong. She spotted sudden, abrupt movement in the plaza. She zoomed in to the action, and swore a blue streak-just as the voices on the headset chimed in, telling her more things she already knew.

“Lentrall’s robot has grabbed him! He’s pulled him under cover!”

Cinta watched the robot shove Lentrall under a bench and cover the opening with his body. He’d been warned. Someone on the CIP had been very smart, and very, very fast. And if they were able to send a warning, that almost certainly meant help was on the way as well. It would have been tough enough spiriting Lentrall away without CIP cops all over the place. She glanced toward the single CIP aircar orbiting the top of the tower. She had hoped the situation up there would have created a sufficient distraction, but it would seem they were only pretending to have been fooled by it.

“Order an abort!” she said. “Cancel! Stop the bus and everyone go home, now!”

“It’ s too late, ma’ am,” the watch controller said. “All the teams are already in motion. The snatch car is already on approach.”

Cinta looked up into the sky, but could not see the snatch car yet. She looked back to the bus, and saw that it was already moving too fast to stop. Another second or two, and it was going to hit.

And then all hell would break loose, even if there was no longer any use for the hell.

“WHAT’S GOING ON?” Davlo Lentrall demanded. “I can’t see a damned thing back here.”

“Good,” the robot Kaelor replied. “Then no one can see you. There is nothing significant happening-”
