Greg was staring into space above her head. "You said fox the furnace 'ware. I get some interesting implications from that. Would you elaborate on that for me, please."

Julia returned her attention to the interview. She would never have picked up on that detail. What kind of an impression had Greg seen? She wanted to ask him: What do minds look like? Didn't think she'd ever have the courage.

"Nothing much to it," Angie said. "Schimel gave me a program to load into the furnace's 'ware, it adjusts the quality inspection sensor records."

"The memox crystals weren't actually contaminated, then," Greg said thoughtfully.

"No. That wouldn't have worked. The security monitors would trip if more than thirty-seven per cent came out bad, see? No way could we ever be allowed to go over the magic figure, that'd blow the whole gaff, right. Reconfiguring the injector mechanism each time you wanted to ruin a batch wasn't on, you'd never get a fine enough control over the output. It's not like flicking on a switch, you know. It takes time to make the blend perfect again, and the time varies. Some of those furnaces are a bitch to run. Then you've got the genuine duff batches to consider. What Schimel's program did was start with the genuine percentage of failures then forge the rest."

Julia sat bolt upright, her tea forgotten. Frustration manifested as a surge of hot blood. She wanted to take Angie by the throat and shake the stupid tart till she rattled. Forty-eight million Eurofrancs' worth of perfectly good memox crystals deliberately dumped into the atmosphere to burn up. It was an appalling thought. Event Horizon's cash reserve reduced to incendiary molecules in the ionosphere.

Walshaw was giving her an entomologist's stare, deciding exactly how worthless she was. And it took a lot to get the coldly civil security chief riled.

Greg was shaking his head in bemusement. "You mean you just chuck away good crystals?"

"Yes," she whispered dully.

Walshaw opened his cybofax. "I want the names of all the other furnace operators you know that are involved."

"Do I have to?" she asked. "I mean you'll find them anyway, won't you?"

"Don't piss me off any further," Walshaw said in a tired voice. "Names."

Julia heard a metallic scrape behind her, and turned in the chair. The manor staff were supposed to leave her alone when she was in here. But it was her father, Dillan, who was opening the library door.
