...Frankenstein's monster speaks: the computer. But where are its words 
coming from? Is the wisdom on those cold lips our own, merely 
repeated at our request? Or is something else speaking? --A voice we 
have always dreamed of hearing?

The Heaven hooks

The manor house of Salt Inspector Castor lay across the top of the hill 
like a sleeping cat. Its ivied walls had never been attacked; the towers 
that rose behind them had softened their edges over the centuries, and 
become home to lichen and birds' nests. Next to his parents, this place 
was the greatest constant in Jordan Mason's life, and his second-earliest 
memory was of sitting under its walls, watching his father work. 
On a limpid morning in early autumn, he found himself eight meters 
above a reflecting pool, balanced precariously on the edge of a scaffold 
and staring through a hole in the curtain wall, that hadn't been there last 
week. Jordan traced a seam of mortar with his finger; it was dark and 
grainy, the same consistency as that used by an ancestor of his to repair 
the rectory after a lightning storm, two hundred years ago. If Tyler 
Mason was the last to have patched here, that meant this part of the 
wall was overdue for some work. 
"It looks bad!" he shouted down to his men. Their faces were an arc of 
sunburnt ovals from this perspective. "But I think we've got enough for 
the job." 
Jordan began to climb down to them. His heart was pounding, but not 
because of the height. Until a week ago, he had been the most junior 
member of the work gang. Any of the laborers could order him around, 
and they all did, often with curses and threats. That had all changed 
upon his seventeenth birthday. Jordan's father was the hereditary master 
mason of the estate, his title extending even to the family name. Jordan 
had spent his youth helping his father work, and now he was in charge. 
For the first four days, Father had hung about, watching his son 
critically, but not interfering. Today, for the first time, he had stayed 
home. Jordan was on his own. He wasn't all together happy about that, 
because he hadn't slept well. Nightmares had prowled his mind.
"The stones around the breach are loose. We'll need to widen the hole 
before we can patch it. Ryman, Chester, move the scaffold over two 
meters and then haul a bag of tools up there. We'll start removing the 
stones around the hole." 
"Yes sir, oh of course, mighty sir," exclaimed Ryman sarcastically. A 
week ago the bald and sunburnt laborer had been happy to order Jordan 
around. Now the tables were turned, but Ryman kept making it clear 
that he didn't approve. Jordan wasn't quite sure what he'd do if Ryman 
balked at something. One more thing to worry about. 
The other men variously grinned, grunted or spat. They didn't care who 
gave them their orders. Jordan clambered back up the scaffold and 
started hammering at the mortar around the hole with a spike. It was 
flaky, as he'd suspected--but not flaky enough to account for the sudden 
outward collapse of stones on both sides of
