As far as he could estimate, two hours passed before he got any further answers, although it was hard to gauge the passage of time in the locked bedroom. The only thing he knew for sure was that he had smoked five more cigarettes before he once again heard the sound of the door being unlocked.

This time it was Klein, who held the door wide and beckoned to Gibson. "Come with me, will you?"

Klein seemed less than friendly. Perhaps he was miffed at Gibson's negative response to his providing him with beer, butts, and breakfast. Gibson followed Klein down the corridor into the living room. The first thing that he noticed was that the model on the chart table had been covered over with a white sheet. Presuming that it was a miniature of the planned assassination scene, they plainly didn't want him looking at it. Smith, French, and Rampton were waiting for him, and, to Gibson's great relief, there was no sign of Burroughs and Wellcome.

Smith came straight to the point. "You'll be pleased to hear that we have provisionally decided to take you up on your offer."

Gibson nodded. "If I cooperate, you'll let me live?"

"That's the gist of it."

"Well, I'm very pleased to hear that. What are the provisions?"

Smith smiled. "Really there's only one. If you try to double-cross us, we'll shoot you out of hand."

"That's direct and to the point."

"It is, of course, a somewhat strange agreement since we don't trust you and I imagine you have equally little faith in us."

Gibson thought about this. "What you might call a conspiracy of mistrust."

Rampton seemed to like this. "There are times, Gibson, when you put things very well."

Gibson looked round the room. A number of the photographs on the walls were different views of the same building. It was a square, seven-story industrial building, either a factory or warehouse, but there was something oddly familiar about it and he couldn't for the life of him put a finger on what it was or where he might have seen it before.

Giving up on the puzzle, he faced Smith. "Since we seem to have the basis of an agreement, shall we get down to business? I'm a little anxious to know what's expected of me. I take it, since you're so friendly with Raus, that you're on the side of the assassins in this plot."

"That's not strictly true."

Gibson raised his eyebrows. "You mean that you're going to try to save the president?"

Smith sighed. "No, we're not doing that either."

"So what's the deal?"

"Essentially we are monitoring events in Luxor. There's no real debate that the administration of Jaim Lancer has been a complete disaster for this country, but this is an internal matter of the UKR, and contrary to popular opinion, we don't actually go around interfering in the domestic affairs of sovereign states in other dimensions. The most that we can do is to nudge events in the direction that we believe will lead to maximum stability in the region."

"And I'm to be a part of this nudging process?"

"In fact you may only be a backup. The assassination will be carried out by Zwald and three other unnamed shooters. Behind them are Raus and a number of other powerful men in the country. Although the mantle of power will naturally fall on Raus and his friends, there will also be a major public outcry following the president's death. Lancer enjoys a totally irrational popularity among the people of the UKR, and there's bound to be a massive outcry following the assassination and probably the need for a scapegoat."

A chill ran up Gibson's spine. "I hope you don't have me cast in that role?"

"It was considered at first but rejected as impractical."

"So who will take the fall?"

"Zwald."

"While Raus gets crowned king?"

Smith's expression was that of the world-weary professional. "Isn't that the way these things are done?"

Gibson went to the window and looked out. Many floors below, people were walking on the sidewalks and traffic was moving up and down the street. The overcast was breaking up, and patches of watery blue sky were showing through. It was a normal day in any big city. "No honor among conspirators?"

"Would you expect any?"

Gibson nodded in slow agreement. "So what do I have to do?"

"Basically, it's very simple. We move you around various locations in the city to confuse witnesses and generally promote the idea of Zwald being a lone-nut assassin."

"Trying for the lone-gunman theory?"

"That's what Raus is looking for."

"And you?"

"We would prefer the most massive conspiracy paranoia that is possible without Raus's position actually being compromised."

"This sounds a hell of a lot like the Kennedy assassination."

"That was one of the models we used for reference."

"And does Raus know about the Kennedy assassination?"

Smith shook her head. "Of course not."

Rampton seemed to feel a sudden need to show off his knowledge. "There's something called the bottleneck theory that puts forward the proposition that certain events are, for all practical purposes, preordained, racked up in the time stream like a bottleneck that has to be passed before the culture of that dimension can move on."

Smith and French exchanged swift angry glances. It was plain that, as far as they were concerned, Rampton had said too much. Smith went into spin control. "I wouldn't worry about the bottleneck theory, Gibson. Many of us don't subscribe to it."

Gibson, however, was a lot more interested in Rampton than he was in the theory. "While all this explaining is going on. how about someone explaining to me what exactly Rampton is doing here?"

Rampton looked at Gibson coldly. "I don't see what concern it is of yours, Gibson."

Smith still didn't seem particularly pleased with Rampton. "Rampton is simply here to observe."

"Like observing the sacrifice to Balg?"

"He's here to study our methods."

Gibson smiled in disbelief. "That seems about as plausible as the CIA taking along a Boy Scout to show him how they work. What did they promise you, Sebastian? To make you king of the hill back in our dimension once they're finished with this one?"

Rampton only kept his temper under control with some difficulty. "At least I'm not begging for my life."

"Don't speak too soon, Jack. You may be yet."

Smith had had quite enough of this. "Really, Gibson, the reasons for Rampton's being here don't concern you."

Rampton's face broke into a faint sneer. "Ever heard the phrase 'need to know,' Joe?"

"The only thing that I need to know is that he isn't going to be coming up behind me at some crucial moment."

Smith put a final stop to the exchange. "You have our assurance on that."

"I seem to be getting a lot of assurances. "

Rampton laughed. "What did you call it, Gibson? A conspiracy of mistrust?"

For the next three days, the streamheat were as good as their word. Gibson was taken by car to various locations in the city and expected to perform simple tasks under the watchful eyes of either French, Burroughs, or Wellcome. He was sent to walk down a specific block, or through the lobby of a building. On one occasion, he had to walk into the offices of a bank and exchange briefcases with a man in a dark suit. Gibson assumed that all this was probably being filmed or photographed or at least watched by a third party who might serve as a witness at some point in the future. Gibson knew that these actions were probably digging him deep and that he was setting up a lot of stuff that could backfire on him if anything went sour. This was an eventuality, however, that he tried not to dwell on. For the moment, he was alive and functioning and that was what counted when you were living on a one-day-at-a-time basis. The fact that he didn't have a solitary clue regarding the relevance of any of the things that he was doing was something else that he preferred not to ponder.
