Wraiths moved through the haze.

As Swinburne led his companions out onto the pavement, the mist parted, and the Claimant came charging out of it like an enraged hippopotamus. Before any of them could raise a weapon, they were sent flying. Swinburne and Spencer both ended up on their backs in the gutter, while Nelson clanged noisily against one of Palmerston's steam-horses. Trounce was grabbed by the collar, yanked off his feet, and thrown high into the air and clear across the road. He thumped down headfirst onto the opposite pavement, rolled, and lay still.

Nelson ducked under the Claimant's swinging fist and scuttled away to retrieve the rapier, which had been knocked out of his hand. Swinburne rolled under the steam-horse and out the other side. He jumped up then backpedalled rapidly when he found himself looking a wraith full in the face.

“Argh!” he cried, and clutched the sides of his head. He felt a terrible pressure on his brain. “No!” he gasped. “I'll not let you inside! Not ever again!”

A gunshot echoed as Herbert Spencer put a bullet into the Claimant's side. The philosopher scrambled to his feet, turned, and ran to the back of the prime minister's carriage. A ghostly hand clutched at his arm. He struggled in the grip of a wraith.

The Claimant flew into a berserk rage. Stamping his feet and waving his arms, he hollered and howled, screamed and hissed, and threw himself into the side of the foremost of the two steam-horses. It must have weighed well over a ton, but under his onslaught, the machine keeled over, narrowly missed crushing Swinburne, and skidded across the cobbles on its side, showering sparks and emitting a plume of white vapour as one of its pipes tore open.

“Mother!” a muffled voice cried from inside the mobile castle's front cabin. “Help me!”

It was Palmerston's driver, who'd been quaking inside the box ever since the wraiths had appeared and caused the deaths of the guards.

The piggy eyes of the Claimant flicked to the source of the sound. In one stride he was beside it, grabbing the edges of the wedge-shaped compartment. He began to heave it back and forth. The man inside wailed piteously.

Swinburne heard himself mutter: “Tichborne! The bloody toffs are-are-are trying to do away with Tichborne!”

He shook his head.

“No!” he growled. “No! No! No! That is not Sir Roger bloody Tichborne!”

He stepped straight through the drifting wraith, levelled the cactus gun, and fired. As he touched the trigger nodule, his arm jerked aside, and the spines flew wide.

“Bloody conspiracy!” he gasped, fighting the words as they forced themselves out of his mouth. As fierce as the battle in the street was, the fight in the poet's head was even more intense.

Admiral Lord Nelson bounded over to the Claimant and lunged in. His rapier danced. He skipped away. Wraiths swooped around him, grabbing at his arms, but they couldn't hold him.

The corpulent creature screamed as two of the lumps on its scalp disappeared, sliced off by the sword blade. Blood gushed from the wounds. Black gems bounced into the gutter.

Swinburne felt a sudden lessening of the pressure on his brain.

“Herbert!” he cried. “Collect the diamonds! We mustn't lose them!”

The Claimant twisted and lumbered after Nelson, who now stood a short distance away in the en garde pose. He reached the clockwork man and there commenced a flurry of arms and blade as Nelson jabbed and sliced at the fat behemoth, while the latter attempted to deflect or catch the flashing rapier.

Herbert Spencer tore himself away from the tormenting wraith and darted forward. He retrieved the two fallen Choir Stones. As he did so, another one fell.

The Claimant let loose a terrific shriek and clutched his head.

“I remember!” he shouted. “I remember!”

Nelson backed away from his opponent, who once again lurched after him. The sleeves of the Claimant's jacket, and the shirt beneath, hung in tatters. When he raised his hands to grab the rapier, his mismatched forearms were fully exposed. They were terribly lacerated, but the creature appeared to be entirely immune to pain.

The rapier danced away from the clutching fingers.

The Claimant roared with frustration.

Herbert crept up behind him and picked up the third stone, then two more as the fourth and fifth flew from the swollen man's head.

Swinburne started to shoot spines into the creature's back, hoping that the accumulating venom would at least slow the juggernaut down.

“I want meat!” the Claimant raged. His face was covered with blood. Every few moments, his tongue snaked from between his lips and licked at the red liquid.

The sixth diamond dropped.

Admiral Lord Nelson started to duck and dodge more intently. The remaining stone was located at the back of his opponent's head, so he needed to somehow manoeuvre himself into a position from which it could be extracted.

As the two combatants moved back and forth over the cobbles, Spencer followed cautiously, slipping the sixth stone into his pocket.

The clockwork man stepped in close, bent under a lashing fist, sprang forward, whirled, and sent his rapier's tip digging into the remaining fleshy protuberance on the back of his adversary's skull. A small chunk of flesh dropped away. Blood spurted. A black diamond sparkled. It landed at Spencer's feet. He snatched it up. He now had the complete Francois Garnier Collection in his pocket.

“Aaaaargh!” the Claimant cried. “Hurts! It hurts! Give me meat! I want meat!”

He turned to face Nelson and backed away a couple of steps, peering through the blood streaming over his eyes.

His fury seemed to leave him for a moment.

He blinked.

Swinburne felt a profound sense of release, as if he was fully himself again. He lowered the spine-shooter and watched.

“No,” the fat man uttered. “No. I am not-I am not-”

He lifted the larger of his two hands up to his face.

“I am not Roger-”

He dug his blunt fingernails into his forehead and cheeks.

“I am not Roger Tichborne!”

With a stomach-churning tearing noise, he ripped his face from the front of his skull and held it out triumphantly.

“My name is Arthur Orton! And I want meat!”

He pushed the drooping skin and tissue into his mouth and started to chew.

“Ah,” Swinburne whispered. “So there we have it at last.”

Arthur Orton considered Admiral Lord Nelson.

“You,” he rumbled, “are not meat.”

His gory countenance, all raw muscle and throbbing veins, turned until he was looking directly at Herbert Spencer.

“But you-”

With startling agility for one so gargantuan, Orton lunged at the vagrant philosopher.

Spencer turned to run.

Admiral Lord Nelson sprang into action. He took two great strides, raised the rapier, sent it plunging toward the back of Orton's spine, suddenly slowed-and froze.

The clockwork man had wound down.

Corpulent fingers closed around Spencer's neck.

Swinburne started shooting, pressing the trigger nodule again and again.

“Trounce!” he shrilled. “Your pistol! Your pistol!”

There was no response. The detective was either out cold or dead.

Spencer yelled as he was yanked off his feet.

“Meat!” bellowed Orton triumphantly and sank his teeth into the back of the philosopher's neck. His victim's scream of agony was cut short as vertebrae crunched and shattered, and a gobbet of pulsating flesh was wrenched free.

Orton twisted Herbert Spencer's head off and threw it to one side. It bounced away across the cobbles. Blood pumped from the severed neck, and the monstrous butcher laughed as it sprayed over his face.

“No,” Swinburne sobbed. “Oh Jesus, please no.”

Holding Spencer's twitching corpse with the larger of his hands, Orton plunged the other into the neck, pushing it deep into the body.
