Ranasfari picked up on the flash of excitement in his voice. "I think I see what you are driving at. Yes. The Merlin failed yesterday morning, eight twenty-four, to be precise."

"After the blitz."

"Correct; approximately ten hours. Do you believe the two events are connected?"

Greg was certain of the connection. But there was a fragment of bedlam jarring what would otherwise have been an immaculate fusion of disjointed thoughts. The implication that it wasn't an obvious union. Yet it seemed straightforward. He almost let out a groan; this was as bad as the memox spoiler.

"The attack against Philip Evans could've been a blind," Greg ventured. "Remember the blitz was perpetrated against the whole Event Horizon network; one of the hackers could easily have tampered with the Merlin control programs while it was going on."

"But why the delay?"

"An attempt at disassociating the events? No, wait a minute, how much altitude could the Merlin add in ten hours? Would it make recovery more difficult?"

"Altitude increase over ten hours would be approximately one thousand five hundred kilometres; you have to remember that at the start of the flight the Merlin masses four times as much as it will when it rendezvouses with its target asteroid. That means a low initial acceleration. But certainly that additional fifteen hundred kilometres would add considerably to the cost of recovery. Its current three-and-a-half-thousand-kilometre orbit is way above the Sanger ceiling. An inter-orbit tug would have to be chartered specially, which is a totally uneconomic prospect. Physical recovery was well down our option list. In fact, given normal circumstances, it wouldn't be considered unless a second Merlin suffered a similar failure. There are a great many conceivable reasons for the shutdown; the giga-conductor cell is not the only new component in series-four models. Few components are common to every Merlin, its development is a continual process of evolution. And, of course, the giga-conductor cells performed perfectly in the space environment simulation tests, they were most extensive."

"But in the meantime a question mark hangs over introducing the giga-conductor cell."

"Yes, unfortunately. A Ministry of Defence team from Boscombe Down has already arrived to review our fault-analysis data."

"What has happened to the Merlin? Is it a total breakdown?" Greg asked.

"It looks like it. The propulsion system has shut down, and the communication link has been severed. It won't even respond to signals directed at its omnidirectional antenna."

"Could its state have occurred by transmitting a rogue set of instructions, ordering it to shut down?"

"Indeed," Ranasfari agreed. "Providing you had the correct codes."

"Which, presumably, are stored here in the Institute's memory cores."

"Yes."

"And are they isolated from the Event Horizon datanet?"

"No."

"So the attack could be an attempt to discredit Event Horizon's giga-conductor, which at the very least would delay military funding of your production lines, giving your rivals an opportunity to make up lost ground."
