"It hurts so much just seeing her," Julia said. "Serves me right, I suppose." She reached round her neck with both hands and unhooked a slim gold chain. "For you. From me. And you don't even have to give me a kiss for it." She favoured him with a sly weary smile.

It was a St. Christopher pendant, solid gold.

"Well, put it on then," Julia said.

He mimicked a grin, feeling itchy under Gabriel's heartily bemused eye, and fastened it round his own neck. The little disk was warm on his skin as it slithered down beneath the open neck of his crisp dress shirt.

"To keep the demons at bay," Julia said. "Even though you're not a believer."

Greg pulled out of the finance division's nearly deserted car park, turning the Duo west on to the artificial lava surface of the A47. There was a single car in front of them. It wasn't quite dawn. The gross Event Horizon sign splashed the surrounding land with a guttering medley of coloured light.

"I feel sorry for that girl, you know," Gabriel said. She was looking out of the window at the clumps of hermes oak scrub along the side of the road. Beyond the bushes was a near-vertical drop to the ruffled waters of the estuary. In the distance were the dark shapes of the hydro-turbine islands, moon-glazed foam rumbling round them.

"Katerina? Who wouldn't?" Greg said.

"No, Katerina is pure survivor breed. I meant Julia; she has no real family, few friends her own age. And you're on the borderline yourself, now, despite her token of esteem."

"How do you figure that?"

"If Ellis hasn't left anything in the Crays, or whatever, about Kendric or the organiser, how do you think she'll feel about you? You've managed to be right all the way so far. She trusts you because of that. Implicitly. Screw up now and it'll all end in tears."

"Not a chance. I know Ellis's type down to his last chromosome. A hyper-worrier. He's a little-man intermediary who's lucked into a real super-rank underclass operation; elated and terrified all at once. He'll have taken precautions. That means a way of pointing his finger from beyond the grave."

"Oh, yeah?"

"Yep. Ellis's major problem was that he never got round to telling his paymasters he was insured." Greg slowed as the car in front turned off on to the sliproad for the bridge ahead, then accelerated again as the cutting walls rose on either side.

Gabriel said: "I still don't think Ellis would take such—"

The front nearside tyre blew out.
