An immigration desk waited for us at the far end. Two Eden police officers in smart green uniforms stood behind it. And I do mean smart: spotless, pressed, fitting perfectly. I held in a smile as the first took my passport and scanned it with her palm-sized PNC wafer. She stiffened slightly, and summoned up a blankly courteous smile. «Chief Parfitt, welcome to Eden, sir.»

«Thank you,» I glanced at her name disk, «Officer Nyberg.»

Jocelyn glared at her, which caused a small frown. That would be all round the division in an hour. The new boss's wife is a pain. Great start.

A funicular railway car was waiting for us once we'd passed the immigration desk. The twins rushed in impatiently. And, finally, I got to see Eden's interior. We sank down below the platform and into a white glare. Nicolette's face hosted a beautiful, incredulous smile as she pressed herself against the glass. For a moment I remembered how her mother had looked, back in the days when she used to smile—I must stop these comparisons.

«Dad, it's supreme,» she said.

I put my arm around her and Nathaniel, savouring the moment. Believe me, sharing anything with your teenage children is a rare event. «Yes. Quite something.» The twins were fifteen, and they hadn't been too keen on coming to Eden either. Nathaniel didn't want to leave his school back in the Delph company's London arcology. Nicolette had a boy she was under the impression she was destined to marry. But just for that instant the habitat overwhelmed them. Me too.

The cyclorama was tropical parkland, lush emerald grass crinkled with random patches of trees. Silver streams meandered along shallow dales, all of them leading down to the massive circumfluous lake which ringed the base of the southern endcap. Every plant appeared to be in flower. Birds flashed through the air, tiny darts of primary colour.

A town was spread out around the rim of the northern endcap, mostly single-storey houses of metal and plastic moated by elaborately manicured gardens; a few larger civic buildings were dotted among them. I could see plenty of open-top jeeps driving around, and hundreds of bicycles.

The way the landscape rose up like two green tidal waves heading for imminent collision was incredibly disorientating. Unnerving too. Fortunately the axial light-tube blocked the apex, a captured sunbeam threaded between the endcap hubs. Lord knows what seeing people walking around directly above me would have done to my already reeling sense of balance. I was still desperately trying to work out a viable visual reference frame.

Gravity was eighty per cent standard when we reached the foot of the endcap, the funicular car sliding down into a plaza. A welcoming committee was waiting for us on the platform; three people and five servitor chimps.

Michael Zimmels, the man I was replacing, stepped forward and shook my hand. «Glad to meet you, Harvey. I've scheduled a two-hour briefing to bring you up to date. Sorry to rush you, but I'm leaving on the Ithilien as soon as it's been loaded with He3 . The tug crews here, they don't waste time.» He turned to Jocelyn and the twins. «Mrs Parfitt, hope you don't mind me stealing your husband away like this, but I've arranged for Officer Coogan to show you to your quarters. It's a nice little house. Sally Ann should have finished packing our stuff by now, so you can move in straight away. She'll show you where everything is and how it works.» He beckoned one of the officers standing behind him.
