I.

The April fool's joke nearly broke the bank.

Arthur Pendleton sat in his corner office on Threadneedle Street, watching his colleagues stampede through the financial district like rats escaping a sinking ship. They had spent three hours buying flour, salted meat, and candles after a fake BBC broadcast announced that the Bank of England had been hacked by a phantom republic called "IT" which threatened to "format the world" at midnight.

Now it was midnight. The world remained unformatted. The交换机 had been disconnected, as young Mr. Wells had pointed out with an unrepentant grin.

"April fool, Arthur!" shouted Mr. Harrison from the next desk, his face flushed from running up and down Cheapside. "You look like you've seen a ghost."

Arthur had not seen a ghost. He had seen something worse: clarity.

He looked at his hands on the desk. They were the same hands that had typed ledgers for twelve years, the same hands that had signed mortgage papers for a flat in Bloomsbury that smelled of damp and cabbage. But they were also hands that were aging. He could feel it—the slight tremor in his left thumb, the way his knuckles looked when he clenched his fist. He was thirty-two years old and already his body was betraying him.

The fake broadcast had done something unexpected. It had removed his hesitation.

"I need to make an appointment," Arthur said quietly.

"With whom? The Bank of England? Too late, they've already formatted us all."

"With Dr. Moreau's clinic. On Harley Street."

Mr. Harrison stopped laughing. "The longevity clinic? Arthur, that costs more than your annual salary."

"I know what it costs."

Arthur had calculated the numbers. Five million pounds. He could get five million pounds. All he had to do was take it from the pension fund accounts he managed, spread across forty-seven transactions over three months. It would be easy. It would be criminal. It would be the best decision he had ever made.

II.

The injection cost him his soul, though he did not know this at the time.

Dr. Moreau's clinic was on Harley Street, between a dentist and a shop that sold walking canes for wealthy gentlemen. The waiting room smelled of lavender and antiseptic. Arthur sat in a leather chair and read a medical journal from 1882 while a nurse counted his pulse and checked his temperature.

"The Elixir," Dr. Moreau said when he entered. He was a small man with bright eyes and hands that did not tremble. "It is not a medicine, Mr. Pendleton. It is a chemical correction. We have identified the enzymatic process by which cells degrade, and we have developed a compound that reverses it. You will not live forever. But you will live longer. Perhaps three hundred years, if you are careful."

Three hundred years. Arthur thought of his father, who had died at sixty-four from consumption. He thought of his mother, who had spent her last ten years in a state of perpetual confusion, not recognizing her own children. Three hundred years.

"How does it work?" he asked.

"We inject a synthetic enzyme that reprograms your cellular aging process. It is safe. It is permanent. It is the future of medicine."

Arthur rolled up his sleeve. The needle was cold. The liquid was warm.

The first month was miraculous. His gray hair at the temples turned dark. The lines around his eyes softened. He had energy he had not felt since he was a boy. He walked faster, thought clearer, slept less. His colleagues at the bank noticed. "You look well, Pendleton," Mr. Harrison said. "Have you been taking something?"

But by the third month, something was wrong.

Arthur would remember doing something—a conversation, a walk along the Thames, a letter he had written—and yet he would not remember feeling anything while he did it. His memories were intact. His facts were correct. But the emotional connection to those memories had been severed, like a wire cut from a bell.

He sat in his flat in Bloomsbury one evening and tried to recall the last time he had kissed Isabella. He knew it had been three weeks ago, at the British Museum, standing in front of the Rosetta Stone. He knew what she had been wearing—a blue dress with white lace at the collar. He knew the exact words he had said: "You look like a painting."

But he could not feel the kiss.

III.

Isabella chose the long sleep.

The Royal Free Hospital was running trials of an experimental hibernation chamber, originally developed for Arctic explorers. Isabella had read about it in the paper and called Arthur immediately.

"I'm going to sleep for five years," she told him over tea in Hyde Park. "When I wake up, the world will be different. And I will not have aged a day."

"And me?" Arthur asked.

"You took the Elixir, didn't you?"

"Yes."

"Then you will be the same age I am when I wake up. Or younger. You will be young when I wake up."

"I don't want to be young without you."

"Arthur, you are not without me. You are just... ahead of me."

They walked along the Thames that night. The fog was thick, rising from the river like breath from a sleeping giant. Arthur held Isabella's hand and tried to feel something—anything—but his heart was a clock that had been wound too tight and was ticking without purpose.

"I will wait for you," he said.

"Will you?" Isabella stopped and looked at him. "Arthur, you have the Elixir. You might wait for a hundred years. Or a thousand. What happens to you in that time?"

"I will be the same man."

"Will you?"

He did not answer. Because he was not sure he was the same man anymore.

The truth came to him six months later, from an unexpected source. Lord Sebastian Windsor, one of the Elixir's earliest users, invited Arthur to a dinner at his town house in Mayfair. There were seven other guests, all of them industrialists, all of them users of the Elixir for more than five years.

Arthur noticed things at the dinner that he had not noticed before. Lord Windsor told a story about the Boer War—no, it was not the Boer War. It was the Afghan campaign of 1879. But Lord Windsor had been only twelve in 1879. He could not have been in Afghanistan.

Another guest, Sir Edmund Thorne, referred to a business deal in India that had taken place in 1865. But Sir Edmund was born in 1855. He would have been ten.

Arthur left the dinner early and went to a library. He spent three nights researching the guest list of Lord Windsor's Elixir parties. He found that every single person at that dinner had claimed to have experienced events that were impossible given their birth dates. They remembered things they could not have remembered. They had lives that did not match their ages.

The Elixir did not just extend life. It replaced the person.

Every time someone took the Elixir, a new consciousness emerged in their body. The old consciousness faded, like a candle burning down to nothing. The new consciousness had the memories of the old one, but it did not feel them. It was like reading a biography of someone else's life.

Arthur looked at his reflection in the library window. The face staring back at him was younger than it had been a year ago. The skin was smoother. The eyes were brighter.

But it was not his face.

IV.

The fog on the Thames was thicker than usual that night.

Arthur sat on a bench by the river, watching the water move slowly beneath the bridges. The fog rose from the river like the breath of something vast and sleeping. Big Ben struck twelve, and each chime felt like a nail being driven into a coffin.

He was thirty-three years old. He had taken the Elixir fourteen months ago. He was not Arthur Pendleton anymore. He was someone who had Arthur Pendleton's memories, Arthur Pendleton's education, Arthur Pendleton's job at the bank. But he was not Arthur. Arthur had felt things. Arthur had loved Isabella with a feeling that was real and warm and human.

This new Arthur felt nothing.

He looked at his hands on the bench. They were the same hands that had typed ledgers for twelve years. But the hands that had typed those ledgers were gone. Dead. Erased like writing on a slate that had been washed clean.

He was a ghost in his own body.

A man walked past him, hurrying through the fog with a lantern held low. Arthur watched him go and felt nothing. Not sadness. Not anger. Not even the absence of feeling—he was beyond that. He was something else. Something that had no name.

The fog swallowed the man's lantern, then the man himself. Arthur sat alone on the bench, listening to the river and the distant sound of carriages on Holborn.

He stood up and walked into the fog. He did not know where he was going. He knew he would live for perhaps three hundred years. He knew he would walk these streets long after the gas lamps were replaced by electricity. Long after the horse carriages were replaced by automobiles. Long after everyone he had ever known was dust.

He would be thirty-three forever.

And he would be no one.

The fog took him, and the Thames kept flowing, and London went on without noticing that one of its residents had ceased to exist while still drawing breath.
