I

The fog came down on Whitechapel like a shroud, thick and suffocating, and Thomas Mourne felt it in his knees before he heard the bell.

He was at his bench, carving a new lid for a child's coffin—no, not a child's, he corrected himself, the boy had been thirty-two, a dockworker crushed between barrels of rum at Wapping. Thirty-two and with three daughters. Thomas always made the coffins to size. He did not believe in standard sizes for human beings.

The bell on the shop door rang. Not the customer's bell—the dead man's bell, the one that rang in his knees three hours before the heart stopped. He felt it now, a creeping numbness in the patella, like frostbite starting from the bone. Someone in this neighborhood would die by dawn.

Thomas looked up. Mrs. Calloway stood in the doorway, her bonnet pulled low, her face drawn thin.

"Mr. Mourne," she said. "There's a young woman at the mission on Commercial Street. She's got the consumption bad. I thought—you know what I thought."

"I know what you thought, Mrs. Calloway," Thomas said, setting down his chisel. "Let me wash my hands."

The mission was a converted warehouse, all drafty corridors and coughing beds. The girl lay on the third bed from the back, which was where Thomas always put the ones he knew were dying. She couldn't have been more than twenty, with dark hair and a face too sharp for her body, her ribs visible through a thin cotton gown.

"May I sit?" Thomas asked.

She looked at him with eyes the color of strong tea. "Are you the undertaker?"

"I am."

"My mother said you're the man they call when the body gets cold. Are you here because I'm cold already?"

Thomas sat on the wooden chair beside her bed. It was a simple chair. It had held a thousand men and women waiting for the end. "I'm here because Mrs. Callay sent me."

"She sends everyone." The girl smiled, and it was a cracked thing, like light through dirty glass. "I'm Ellen. I sing at the music hall on Farringdon Road."

"Thomas Mourne."

"I know who you are, Mr. Mourne. Everyone in Whitechapel knows the undertaker who never smiles."

He didn't correct her. He did smile, sometimes. But not here, not now.

In the weeks that followed, Thomas came every evening. He brought broth from the tavern downstairs and books from his mother's collection—she had been a reader, before the fever took her, before the knees had started their terrible work. Ellen sang to him sometimes, her voice thin and wavering, like a candle in a draft. She sang ballads about sailors and mothers and girls who died young. She sang them all beautifully.

And every night, Thomas felt his knees growing heavier, as if the weight of every corpse he had ever prepared was settling into his joints.

III

One December evening, Thomas brought something unusual: a small silver music box, bought from a jeweler on Fleet Street. He placed it on Ellen's bedside table.

"For you," he said.

Ellen wound it and the little mechanism played a soft waltz. She closed her eyes and listened, and for a moment, the consumption didn't seem to matter. She was just a girl in a room with music.

"You shouldn't have," she whispered when it ended.

"I wanted to."

Thomas stood to leave, as he always did. But something stopped him. He looked down at Ellen's father, who had come to sit beside her daughter's bed—a lean, hard-faced man with hands like drumsticks from years of working the docks.

And Thomas felt it: the kneeling.

It started in his left knee, a pressure building from deep inside the joint, the way it always did when a death was near. But this was different. This was not the numbness of the approaching death. This was the desperate, physical need to bend his knees, to lower himself to the floor before this man, to say I love your daughter and I will miss her and I am so sorry without using words.

He gripped the back of the chair. His face went white.

"Mr. Mourne?" Ellen's voice, thin with worry.

"I must go," he said, and he walked out into the fog, his knees burning.

Ellen died on a Tuesday morning, in the pale light that comes in December before the sun has properly risen. Thomas was there. He held her hand and watched her breathing slow and stop, and he did not kneel.

At the funeral, her father stood at the grave and did not weep. Thomas stood beside him and did not weep either. But when the dirt began to fall onto the coffin—mahogany, the finest he had ever made—Thomas's knees buckled.

He hit the frozen ground hard. The mud splashed his trousers. The priest stopped talking. Ellen's father turned and looked at him with something between confusion and fear.

Thomas did not care. He pressed his forehead against the cold earth and felt, for the first time in his forty-three years, what it meant to be human. The weight of it—the absolute, crushing weight of loving someone you cannot keep—pressed him into the ground like a tombstone.

Hours later, alone at the grave, Thomas understood what he was. He was not a man. He had never been a man. He was the last undertaker—the one God sent to prepare the dead for their journey, the one whose knees belonged only to the graves of the world. And he would kneel at every grave until the last grave was dug, and then he would kneel at his own.

He rose slowly, his knees caked in mud and blood from the frozen earth, and walked away into the fog of Whitechapel, where another bell was already ringing for another death.
