The creatures come out at night, while we’re asleep. My husband says they are harmless. “Probably mice,” he says. “They’re not harmless,” I tell him. “They are very much not harmless,” I say. “They’re gathering information on us. They’re looking through our things, examining our lives, deciding if we are good or if we are not.” “That’s ridiculous,” my husband says. “They’re singling us out. Deciding which ones to take away.”

Wild Bill “The Buck” Williams rode into town for a drink, but he stayed for the pretty boys. He was as mean as they said but not so tall: a lean, hard man with a rocky face and a broad mustache, slicked at both sides from a tin of fat he kept in a satchel round his waist. That first night he broke a man’s jaw for cheating him at poker. I didn’t just hear the story, I saw it—how Wild Bill clocked the fucker upside the face, emptied the last of his drink, and knocked out half the man’s teeth with his mug.

When I was sixteen, I sold my teeth each Thursday, and that is how I first met the doctor. This was before his celebrated school, his fame, his dogged pursuit of bodies for his collection, back when he was very young and took his income as a dentist.

She squeezed it tight against her side: Hush, hush. “Step aside, ma’am,” said a man in a grey uniform.
