The epidemic came in the tenth week, and it took me out of the palace and into the world, and it broke something in me that had not broken since I died.
It started in the western wards, the poor districts pressed against the outer wall — a fever with a rash, spreading fast through the crowded lanes where whole families slept in single rooms and drew their water from shared wells. By the time word of it reached the palace it was already killing, mostly children, mostly the poor, and the court's response was the response of courts in every century: to seal the district, forbid movement, and wait for it to burn itself out behind a wall, counting the dead from a safe distance as a problem of hygiene and bad fate.
I could not stay behind the wall. I think you know that about me by now.
The way out was Granny Lin, and the cover was charity, and the charity — this is the part I did not let myself understand at the time — belonged to Noble Consort Wei. When the fever spread, it was the Consort's foundling houses and her free-physician program that organized the relief, because that was what she was famous for, that was the soft beloved infrastructure that made her untouchable: when the poor were dying, the kind Consort's people went in. And her people needed hands, and did not ask the rank of a hand that could work, and so I passed through the sealed gate into the dying district as one more nameless volunteer in the Consort's mercy, and I did not once stop to wonder why a woman I was half-hunting had a standing army of loyal, grateful, invisible agents embedded in every poor ward of the capital. I was too busy with the sick. That was always how she won. She gave you something more urgent to look at.
The city undid me. I had glimpsed it over walls; I had not walked in it. And walking in it — the ten thousand roofs, the cook-smoke, the markets and the temples and the beggars and the children, a whole civilization living and dying four hundred years before mine — I felt the size of where I was for the first time all the way to the bottom. This was not a stage set for a palace intrigue. This was a world, entire, full of people as real as any I had lost, and I was in it, and it needed exactly the thing I knew how to do.
And I could not do it. That was the wound the fever gave me, deeper than any blade.
Because I knew what it was. God help me, I knew. The rash, the fever, the spread along the water — some form of typhoid, or something near it, a thing of contaminated wells and crowded rooms, a thing that in my world was a course of pills and a bag of fluid and a survivable inconvenience. I knew how it moved and I knew how to stop it moving: clean water, separation of the sick, boiling, handwashing, the humble unglamorous science of breaking a chain of transmission. That much I could do, and I did it, and it saved more than anyone expected, and it built my name in those lanes into something that outlived me. I had them boil the water and move the wells and burn the soiled cloth and wash, wash, wash, and the dying slowed, and the Consort's grateful physicians watched the strange fierce servant-woman and did as she said because she was so obviously right, and I bought a district's worth of lives with nothing but the germ theory and a loud voice.
But the ones already sick, the ones burning, the children — for them I had clean water and cool cloths and my own two hands and nothing, nothing else. No fluids to hang. No pills. Nothing but nursing and prayer and the body's own fight, which the smallest bodies lose. I sat with a mother in a single room for a night and a day. Her daughter was four years old — a child I could have saved in my old life with a needle and a bag and an hour. She burned down and dried out and died in my arms, of a thing I had cured a hundred times. The one thing that would have saved her was a bag of salt water and clean sugar in the right proportion, run into a vein through a needle I could not make. And I knelt on that floor with all my knowledge and all my useless modern certainty, and I could not save a child from thirst.
I have lost patients. I told you: I have pronounced a lot of people dead. But I had never before lost one I knew how to save and simply could not, for want of a thing my whole vanished world took for granted. That is a particular species of grief, and it lives in me still. It is the true price of where I landed, deeper than the loss of my phone or my brother or my name. I carry, in this life, the knowledge of every person I could have saved with tools that will not exist for four hundred years, and I cannot put it down, and I would not if I could, because forgetting it would be a worse betrayal than being unable to act on it.
I came out of that district changed. Harder in some places and softer in others, the way you come off any war. And I came out carrying, without yet knowing it, the first true thread that led to Wei. In the long nights in the wards I had watched her relief network move. I had seen how deep it ran, how loyal it was, how completely it went where it wished through a sealed and frightened city. And some cold surgeon's corner of my mind had made a note it would not let me read yet: whoever commands this could move anything, anywhere, and no one would ever question a mercy.
