Des dodged the big freighters anchored in the middle of the river outside the port. They were waiting for the early-morning tide to provide the draught they needed to take them down the channel to the Wash. Rust-streaked metal giants, sprinkled with tiny navigation lights, their bows a check pattern of hoarfrost where their liquefied gas tanks nestled against the hull. Greg could hear a steady plop plop plop as chunks of the mushy rime fell into the water.

Once the freighters were left behind it was a straight ride up the Nene to the Ferry Meadows estuary. The Trinities loosened up, schoolboys returning from a day outing. Their hive-buzz chatter percolated about the inflatable—Minim crewmen I have zapped.

Des even had a beacon to aim at. Philip Evans had chosen to celebrate his company's triumphant return to solid land with a thirty-five-metre-high sign perched on top of Event Horizon's finance division offices. Its core was a macramé plait of colourful neon tubes orbited by stylised holographic doodles—expanding geometric graphics, cartoon characters, origami birds, and, at Christmastime, a traditional Santa replete with sledge and reindeer. Monumentally vulgar, but mesmerising at the same time.

The deep-throated gurgling of the tidal turbines grew steadily louder as they drew near the little quay jutting out from the steep concrete embankment below the ugly cuboid building.

Victor Tyo was waiting for them, huddled in a parka against the fresh pre-dawn air rising off the estuary. He offered a gentlemanly hand to Gabriel, then grappled a semiconscious Katerina ashore. She groaned as her bare feet touched the cold concrete.

"Why are her hands tied?" Victor asked reasonably, as Greg stepped ashore and took some of the weight.

"Coz there wasn't enough rope for her fucking neck," Suzi growled out of the dark.

Victor peered down at the inflatable dinghy with its oblique cargo of well-armed hardliners and an underage girl in a revealing gold party frock. "Bloody hell."

Des gunned the throttle and the little craft surged out into the darkness. "See ya, Greg," Suzi called. "And take care of Lady Gee, she's outta this world."

Walshaw and Julia were waiting in a big corner office on the third floor. Rachel Griffith stood outside. It was a monastically simple room; the walls and ceiling were painted a uniform white, contrasting against the all-black fittings. Greg knew it was Walshaw's office without having to be told. An extension of his personality. Comfortable, efficient, and uncluttered. The furniture was unembellished, two chairs in front of a broad desk, a settee against the wall. Honey-yellow louvre bunds shut out a view of what Greg's sense of direction told him would be the estuary. The air was warm and slightly damp; stale, the way it got after people had been breathing it for several hours.

Walshaw was sitting behind the desk when they walked in. Greg was surprised to see the surface covered in little balls of scrunched-up paper.
