The music stopped.

“Herr Handel,” Eliza said, for she had recognized the conductor, “pardon me, but-”

She was interrupted by a voice from the stage, incredibly loud. It was Sir Epicure Mammon in the latest fashions, prancing across a London square with his dodgy sidekick, Surly.

Come on, sir. Now, you set your foot on shore

In novo orbe; here’s the rich Peru;

And there within sir,

[gesturing at the front of a noble town-house fronting on the square] are the golden mines, Great Solomon’s Ophir!

Eliza cowered for a moment-those theatre-going habits again. Then she returned to the pit wall to discover Georg Friedrich Handel looking at her, a bit slack-jawed. Having confirmed that this really was the Duchess of Arcachon-Qwghlm, albeit in a state of deshabille only dreamed of by most gentlemen, he executed a perfect court-bow, deploying his conducting-staff as counterbalance.

“I am sorry, I did not understand that this was a full rehearsal!” she exclaimed.

Behind Epicure Mammon and Surly, a carpenter was kneeling down to tack a bit of stage-dressing in place, and to one side, a painter was daubing away at a trompe l’?il sky. Mammon scowled at her. She raised a hand to her mouth in apology.

“My lady,” exclaimed Handel, reverting, in his astonishment, to German, “what has brought you here?”

“This night,” insisted Mammon, “I’ll change all that is metal in thy house, to gold. And early in the morning, will I send to all the plumbers, and the pewterers, and buy their tin, and lead up; and to Lothbury, for all the copper.”

“What, and turn that, too?” asked Surly, expertly feigning amazement, but at the same time, somehow managing to favor Eliza with a wink; Mammon might scorn her, but Surly knew a beautiful woman when he saw one.

“Yes,” said Sir Epicure Mammon, “and I’ll purchase Devonshire, and Cornwall, and make them perfect Indies! You admire now?”

“No, faith,” said Surly. But he muttered the line distractedly. Having Eliza below was bad enough; but, too, it was impossible to ignore the uncouth noises off from stage right: blurted exclamations, grunts, and ring of steel on steel. Even the musicians, who had been transfixed, for a few moments, by the apparition of a Duchess, had begun turning their heads to look.

The stage of the Italian Opera was uncommonly deep, making it famous among those who loved magnificent sets, and infamous among those who wanted to hear the words. A vast canvas had been stretched across the back of it, and painted to look like an idealized vision of Golden Square, stretching off into a hazy distance; before it, model town-houses had been erected, to perfect the illusion. It tricked the eye very well until a bloody, slashed-up man vaulted over the parapets and rolled to the ground in the deep upstage; he looked like a giant, thirty feet tall, fe-fi-fo-fumming around Golden Square and bleeding on the bowling-green. Which was most inexplicable, until a moment later the very fabric of the Universe was rent open; for a blade of watered steel had been shoved through the taut canvas upstage, and slashed across it in a great arc, tearing the heavens asunder. Through the gap leapt Jack Shaftoe; and then giants duelled in Golden Square.

Jack had a blade that would slash through limbs as if they were melons, but it was heavy and slow. With his tiny small-sword, de Gex could not slash, but he could poke a man through in five places before the victim could say “ouch.” Jack kept humming his scimitar through the space separating him from de Gex, to keep the other from advancing in range for a fatal lunge. De Gex maneuvered round those terrifying cuts, though diverse slashes on his arms suggested he had only just avoided some. He was studying Jack, awaiting the one mistake that would give him an opening to lunge through.

Epicure Mammon and Surly had conceded center stage to the duellists, and now stood at the edges of the proscenium-bit players, forgotten. The painter and the carpenter were on their feet, each torn between fear of the blades, and lust to avenge the damage wreaked on their work by Jack and de Gex respectively. It presently became clear that each of the duellists had a strategy as well as tactics. De Gex was waiting for Jack to become exhausted, which must happen soon. Jack was backing de Gex towards the brink of the stage; this would put him in a position to be hacked to pieces, unless he wanted to chance a jump down into the pit. Understanding this well enough, the musicians had already gone into motion: the violins and woodwinds were crowding into the corner farthest from de Gex and filing out through a door, not far from Eliza, that gave access to the floor of the house. The cellists and bassists were trying to decide between saving themselves, and saving their instruments. Handel was absolutely disgusted. “Get back in your chairs, all of you! You are being paid for five acts, not two!” But de Gex’s boots were already at the edge of the stage, his blood was dripping onto the kettledrums, with faint sounds like reports of distant cannons, and the pit was depopulated. Handel tried to collar a fleeing cellist, and wound up holding a cello. Eliza passed its owner on his way out as she was going in. For she feared Handel did not reck the danger. She rushed across the pit and divested him of the cello and set it down on its tail-pin, cradling its narrow neck in her hand. “Let us find a way out,” she said. She reached to place her hand on his epaulet but grasped only air, for the composer was storming toward the kettledrums. “Let us leave these very dangerous men to-”

But all was now overturned in an instant. Jack had got de Gex where he wanted him, and was winding up for a death-blow, when the painter ducked in, and flung a whole bucket of white paint into Jack’s face.

There was a moment of stillness. Then de Gex began hopping round into a new position: he’d been ready for a leap into the percussion section, and now needed to make a lunge for Jack’s heart. He had nearly gotten ready when Handel, standing below him in the pit, tossed his staff straight up, caught the end of it in both hands, and swung it round in a mighty hay-maker, catching one of de Gex’s shins with such violence that the blood-slick foot was knocked back and off the edge of the stage. The rest of de Gex shortly followed. He made a flailing backwards fall into a kettledrum. One leg and an arm-his sword-arm-ruptured the drumhead and ended up beneath him in the immense copper kettle. The other limbs sprawled over its rim like claws of a lobster that does not wish to be cooked.

Handel had been left off-balance by his mighty swing. De Gex lashed out with his free hand and caught the composer’s lace cravat in a bloody grip. He jerked hard, desperately trying to pull himself out. Eliza reacted before she could think. Her free hand dropped to the bridge of the cello. She raised it on high as her other hand levered the neck down toward the floor, and she launched it across the pit in a high arc. It rotated as it hurtled through apogee, and came down like a javelin, its whole weight concentrated behind the tail-pin. When it stopped, it was sitting on de Gex’s chest. It lodged there at an angle, emitting a spectral chord as the life sighed out of de Gex. He let go of Handel’s cravat.

The composer picked up his staff from the floor and righted his periwig. “Fifth page, second bar!” he called out. But the musicians were slow to return.

Eliza looked up and found a burst of paint where Jack had been, and a trail of white footprints leading out to backstage and Unicorn Court.

She was thinking about the prophecy Jack had alluded to. Jack styled it a prophecy, anyway; in her mind, it had been more in the nature of a blunt promise. She had spoken it to Jack twelve years ago, in the Petit Salon of the Hotel Arcachon in Paris, with Louis XIV as witness. Most inconveniently, she had forgot the exact wording of it. It had been something along the lines of that Jack would never see her face nor hear her voice until the day he died. Eliza being something of a stickler for promises and commitments, she now reviewed the last few minutes’ events in her mind, and satisfied herself that this one had not yet been broken. At no time had Jack gotten a look at her, for his gaze had been fixed on de Gex the whole time, or at least until he’d gotten a bucket of paint in the face. And she had not spoken any words he was likely to have heard.
