Henry suppressed a sigh. When the divorce from Geena was finalized — when he learned the Shoemaker was canned and he was going to have to leave Houston — it was as if his life was ending. He was glad when that crummy BA 747 left the tarmac at Houston Intercontinental, because it was like a little death.

But, unlike whatever lay beyond death, Edinburgh contained people, and choices, and already, just a few hours here, Henry had, on a whim, made two enemies and one dubious friend. And for what?

Anyhow, it was done.

Mike dropped him at the hotel, and Henry lugged his suitcase inside. Mike drove back to the King’s Buildings; he said he wanted to start work, preparing for the first samples from 86047.

Henry checked in.

The room rate was quite fantastically expensive. What was it with Brit hotels? Henry wasn’t paying, but he hated to waste money; the sooner he got out of here the better.

Still, his room wasn’t so bad. A big double bed — a duvet, not blankets — and a kettle and a whole stack of tea bags and a mini bar, and complimentary sunscreen in the bathroom. He was on the fifth floor, and he was looking east; he would get the sun in the morning.

He took off his shoes and his stinking socks, and padded to the window.

Looking north beyond the city’s roof tops he could see the Firth of Forth, a dreamy-blue arm of the sea. Calton Hill pushed out of the foreground. Calton was one of the ancient volcanic plugs that underpinned the city. It was coaled with grass, and crowned by absurd-looking classical-style buildings, such as an open portico — some kind of unfinished temple, it seemed — and a telescope lower.

Mike had been right that Edinburgh was the home of geology. The old igneous structures here had been studied right from the beginning of the discipline. In fact James Hutton in the eighteenth century, based in Edinburgh, was the first to come up with modern theories of the processes that shaped Earth — the first man in history, perhaps, to understand the extent of the vast deserts of geological time that surrounded him.

Henry wondered, briefly, how that must have felt: to be the only human on the planet who knew…

I ought to sleep, he thought.
