It also housed the team which had cracked the giga-conductor. Philip Evans had brought Dr. Ranasfari back to England after the Second Restoration, wanting to keep a tight rein on his Company's resident genius. Setting him up at the Astronautics Institute had been Morgan Walshaw's idea.

With so many recently assembled research and design groups scattered throughout the old museum buildings while they waited for their new facilities to be completed, the place was in a constant state of flux. Ranasfari's team could establish themselves in an office and laboratory unit at the centre and remain unnoticed amongst the flustered crowd. The lost in plain view concept had worked for two years.

"No wonder Evans was so upset when the memox began to affect Event Horizon's profit margin," Greg said as they drew close to the Institute's gates. "How much did this lunatic conceit cost him, for Christ's sake?" The data squirted from Philip Evans's NN core into his cybofax concerning the Institute had only given him generalities, PR gloss. No hard financial facts.

Gabriel answered with a shrug. He sensed a cold trickle of intimidation damping her thought currents.

The Institute was circled by a mushroom ring of ten geodesic spheres housing the satellite uplinks. On the eastern side was a peculiar horn-shaped antenna, unprotected from the elements. It had a temporary look to it. People were walking among the dove-grey Portacabins at its base, ant-size. The damn thing must've been thirty metres high. Scale here something else again.

Greg had a shrewd idea that that was the source of Gabriel's dismay. She'd grasped the Institute at once. With him, the ego-ablating effect was taking time, a slow dawning of his own utter insignificance.

A four-metre chain fence topped by razor-wire marked out the perimeter. There was a smaller fence inside, fine granite chippings between the two. A guard-dog run, or at least some form of hunt animal.

The entrance road was split into five channels, each with a pole barrier. Greg chose number one. The Duo had to pass over ratchet spikes before they got to the red-and-white-striped barrier.

"What does he keep in here?" Gabriel muttered. "Crown jewels?"

"Oh no, something far more valuable than that. Knowledge."

A company bus drew up in lane two, full of sanitised young technical types, all of them wearing pale shirts and neat ties. Greg showed his new Card to the white watchman pillar, and the barrier raised itself obediently.

"But can we get out so easily?" Gabriel asked.

"Your department."

There were three parking yards. He found a space in the first, in the shadow of a big JCB. Gabriel climbed out, twisting her pearls self-consciously. The air was stifling, so Greg slung his leather jacket over his shoulder.
