I, Raf, keeper of my sister's story, will say one last thing. If you ever see the crooked house with the lamp in its window, knock three times. If someone answers, listen to what they ask. Offer your hand, but not your ledger. And if they refuse, respect the refusal. Some lives are not meant for public accounting. Some hearts must remain private, and some mysteries are small mercies meant to be kept.

Rob agreed. He signed whatever small promise she offered with a handshake and a bag of cigarettes. She performed a thing that looked like knitting the air; she threaded silence into sound and pinned a memory to its place in his sister's chest. The woman awakened humming a tune as if she'd never been gone.

I began to write the chronicle more obsessively after that, as if the act could patch the tears in our lives. Writing means ordering; ordering makes predation visible. I wrote down every favor my sister ever did, every trade, every promise. Names leaked like water on paper—Ms. Powell who reclaimed her childhood, the twins who traded their names for the ability to see the future of birds. I started keeping a separate ledger of the things that had not been returned: patience, years of sleep, the shape of a city at dawn.

The wolves continued to prowl. They did not find the map. The priest's fury softened into ambivalence and then, predictably, into charity. People forgot the fear that had motivated them like everyone forgets an older cold. But the town never quite returned to the small complacency it had enjoyed before. It had a scar, like a contraction in the muscle of its self-regard.

I wrote because a life that contains a witch should not be left to rumor. If I were ever questioned—by grief, by disbelief, by friends who meant well and police who regarded unusualness as polite fiction—my pen would be the slow, inexorable force that proved what we had been: real.

My sister read the contract and then folded it in half and in half again until the paper resembled a stone. She said, "No."
