The difference engine

1855: The Industrial Revolution is in full and inexorable swing, powered by steam-driven cybernetic Engines.  Charles Babbage perfects his Analytical Engine and the computer age arrives a century ahead of its time.  And three extraordinary characters race toward a rendezvous with history—and the future:
 
Sybil Gerard—a fallen woman, politician’s tart, daughter of a Luddite agitator
 
Edward “Leviathan” Mallory—explorer and paleontologist
 
Laurence Oliphant—diplomat, mystic, and spy.
 
Their adventure begins with the discovery of a box of punched Engine cards of unknown origin and purpose.  Cards someone wants badly enough to kill for….
 
Part detective story, part historical thriller, The Difference Engine is the collaborative masterpiece by two of the most acclaimed science fiction authors writing today.  Provocative, compelling, intensely imagined, it is a startling extension of Gibson’s and Sterling’s unique visions—and the beginning of movement we know today as “steampunk!”

The Angel of Goliad

Composite image, optically encoded by escort-craft of the trans-Channel airship Lord Brunel: aerial view of suburban Cherbourg, October 14, 1905.

A villa, a garden, a balcony.

Erase the balcony’s wrought-iron curves, exposing a bath-chair and its occupant. Reflected sunset glints from the nickel-plate of the chair’s wheel-spokes.

The occupant, owner of the villa, rests her arthritic hands upon fabric woven by a Jacquard loom.

These hands consist of tendons, tissue, jointed bone. Through quiet processes of time and information, threads within the human cells have woven themselves into a woman.

Her name is Sybil Gerard.

Below her, in a neglected formal garden, leafless vines lace wooden trellises on whitewashed, flaking walls. From the open windows of her sickroom, a warm draft stirs the loose white hair at her neck, bringing scents of coal-smoke, jasmine, opium.

Her attention is fixed upon the sky, upon a silhouette of vast and irresistible grace--metal, in her lifetime, having taught itself to fly. In advance of that magnificence, tiny unmanned aeroplanes dip and skirl against the red horizon.

Like starlings, Sybil thinks.

The airship’s lights, square golden windows, hint at human warmth. Effortlessly, with the incomparable grace of organic function, she imagines a distant music there, the music of London: the passengers promenade, they drink, they flirt, perhaps they dance.

Thoughts come unbidden, the mind weaving its perspectives, assembling meaning from emotion and memory.

She recalls her life in London. Recalls herself, so long ago, making her way along the Strand, pressing past the crush at Temple Bar. Pressing on, the city of Memory winding itself about her--till, by the walls on Newgate, the shadow of her father’s hanging falls . . .

And Memory turns, deflected swift as light, down another byway--one where it is always evening. . . .

It is January 15, 1855.

A room in Grand’s Hotel, Piccadilly.



One chair was propped backward, wedged securely beneath the door’s cut-glass knob. Another was draped with clothing: a woman’s fringed mantelet, a mud-crusted skirt of heavy worsted, a man’s checked trousers and cutaway coat.

Two forms lay beneath the bedclothes of the laminated-maple four-poster, and off in the iron grip of winter Big Ben bellowed ten o’clock, great hoarse calliope sounds, the coal-fired breath of London.

Sybil slid her feet through icy linens to the warmth of the ceramic bottle in its wrap of flannel. Her toes brushed his shin. The touch seemed to start him from deep deliberation. That was how he was, this Dandy Mick Radley.

She’d met Mick Radley at Laurent’s Dancing Academy, down Windmill Street. Now that she knew him, he seemed more the sort for Kellner’s in Leicester Square, or even the Portland Rooms. He was always thinking, scheming, muttering over something in his head. Clever, clever. It worried her. And Mrs. Winterhalter wouldn’t have approved, for the handling of “political gentlemen” required delicacy and discretion, qualities Mrs. Winterhalter believed she herself had a-plenty, while crediting none to her girls.

“No more dollymopping, Sybil,” Mick said. One of his pronouncements, something about which he’d made up his clever mind.

Sybil grinned up at him, her face half-hidden by the blanket’s warm edge. She knew he liked the grin. Her wicked-girl grin. He can’t mean that, she thought. Make a joke of it, she told herself. “But if I weren’t a wicked dollymop, would I be here with you now?”

“No more playing bobtail.”

“You know I only go with gentlemen.”

Mick sniffed, amused. “Call me a gentleman, then?”

“A very flash gentleman,” Sybil said, flattering him. “One of the fancy. You know I don’t care for the Rad Lords. I spit on ’em, Mick.”

Sybil shivered, but not unhappily, for she’d run into a good bit of luck here, full of steak-and-taters and hot chocolate, in bed between clean sheets in a fashionable hotel. A shiny new hotel with central steam-heat, though she’d gladly have traded the restless gurgling and banging of the scrolled gilt radiator for the glow of a well-banked hearth.

And he was a good-looking cove, this Mick Radley, she had to admit, dressed very flash, had the tin and was generous with it, and he’d yet to demand anything peculiar or beastly. She knew it wouldn’t last, as Mick was a touring gent from Manchester, and gone soon enough. But there was profit in him, and maybe more when he left her, if she made him feel sorry about it, and generous.

Mick reclined into fat feather-pillows and slid his manicured fingers behind his spit-curled head. Silk nightshirt all frothy with lace down the front--only the best for Mick. Now he seemed to want to talk a bit. Men did, usually, after a while--about their wives, mostly.

But for Dandy Mick, it was always politics. “So, you hate the Lordships, Sybil?”

“Why shouldn’t I?” Sybil said. “I have my reasons.”

“I should say you do,” Mick said slowly, and the look he gave her then, of cool superiority, sent a shiver through her.

“What d’ye mean by that, Mick?”

“I know your reasons for hating the Government. I have your number.”

Surprise seeped into her, then fear. She sat up in bed. There was a taste in her mouth like cold iron.

“You keep your card in your bag,” he said. “I took that number to a rum magistrate I know. He ran it through a government Engine for me, and printed up your Bow Street file, rat-a-tat-tat, like fun.” He smirked. “So I know all about you, girl. Know who you are . . .”

She tried to put a bold face on it. “And who’s that, then, Mr. Radley?”

“No Sybil Jones, dearie. You’re Sybil Gerard, the daughter of Walter Gerard, the Luddite agitator.”

He’d raided her hidden past.

Machines, whirring somewhere, spinning out history.

Now Mick watched her face, smiling at what he saw there, and she recognized a look she’d seen before, at Laurent’s, when first he’d spied her across the crowded floor. A hungry look.

Her voice shook. “How long have you known about me?”

“Since our second night. You know I travel with the General. Like any important man, he has enemies. As his secretary and man-of-affairs, I take few chances with strangers.” Mick put his cruel, deft little hand on her shoulder. “You might have been someone’s agent. It was business.”

Sybil flinched away. “Spying on a helpless girl,” she said at last. “You’re a right bastard, you are!”

But her foul words scarcely seemed to touch him--he was cold and hard, like a judge or a lordship. “I may spy, girl, but I use the Government’s machinery for my own sweet purposes. I’m no copper’s nark, to look down my nose at a revolutionary like Walter Gerard--no matter what the Rad Lords may call him now. Your father was a hero.”

He shifted on the pillow. “My hero--that was Walter Gerard. I saw him speak, on the Rights of Labour, in Manchester. He was a marvel--we all cheered till our throats was raw! The good old Hell-Cats . . .” Mick’s smooth voice had gone sharp and flat, in a Mancunian tang. “Ever hear tell of the Hell-Cats, Sybil? In the old days?”

“A street-gang,” Sybil said. “Rough boys in...
