Walshaw shook his head in dismay, lips drawn taut. "This means we're going to have to open the field of enquiry to include the whole security division headquarters staff, two hundred and eighty personnel." He cocked an eyebrow at Greg. "Exactly how many interviews can you handle?"

"Tell you, not that many, not in the timescale we'd need. Remember, if this mole exists, he'll know we're gunning for him now, he'll be watching for us. At the first sign of any security operation geared to pinpointing him he'll vanish—if he hasn't already. My advice is work from the other end, that way we can keep the operation at a manageable level; track down the blitz hotrods and the people who paid them, and then we'll find out if there is a mole in your senior staff."

"You just said there was!" Philip sounded irritated.

"Covering my options."

"Bloody hell."

"If it is just one person, then it's going to be a very senior staff member," Walshaw said. "The security around the NN core was rock-solid, damn it."

"A staff member or an executive assistant," Greg said. "Someone who had access to financial records, and saw how much money was being spent on an ultra-hush bioware project."

Walshaw took a stiff breath. "Possible," he said.

Greg's espersense registered exactly how much the admission cost him. "OK, back to the hotrods," he said. "Is the Ministry of Defence the only outside institution you've informed about the giga-conductor?"

"Yah," said Julia. "Bringing them in was an integral part of Grandpa's campaign."

"Oldest dodge in the book," Philip said. "Offer the military a worthwhile new technology, and they fund its development from shaky prototype right the way through to fully functional operational status; then you tack civil applications on the back at minimum cost. The production-facility pump has already been primed by good old taxpayers' cash."

"They leapt at it," Julia confirmed. "The country's entire defence forces have to be rebuilt after the PSP virtually dismantled them. And we can provide them with a new generation of high-energy global-range weapons. Concepts even the Germans and Americans haven't got yet."

"The whole world is going to be hammering on our door," Philip Evans said gleefully. "The fees from licence production will rake in a couple of billion Eurofrancs each year alone, minimum; then there's our own profits. Think of how Event Horizon will grow with that kind of annual investment in its infrastructure."

"The Ministry of Defence will conduct their own inquiry, of course," said Morgan Walshaw. "See if any of their personnel were the source of the leak. And if they were, who the data was channelled to. We've told them that the blitz was aimed at the lightware crunchers we use in the giga-conductor project. There's no need for them to know about the NN core."
