The Cleaning Lady patted her hand and smiled. “The stories we could tell, the things no one ever remembers. It could make your head spin. But if you’ve had that strange feeling that you’re in a room and you don’t know why, or felt that you should be doing something but can’t remember what, you can be pretty sure you’ve just had something erased. It doesn’t have to be big or anything, sometimes just a small part of a larger puzzle.”

Everyone was silent around the table. We all knew we had heard too much, and that led to only one possible outcome for the evening.

“We’re not going to remember any of this, are we?” said Friday.

“Maybe when you’re older, small shreds of Aornis’ death will filter up from the deep subconscious, but they will be unclear and indistinct, no more real than half-forgotten dreams.”

“What about Jenny?” I asked. “What will happen to her? She’s so strong in my mind that I can smell her. I can’t imagine her not being there any more than I can imagine Friday or Tuesday or Landen not being here.”

“You’ll never know she was ever there,” said the Cleaning Lady. “There was only ever one Jenny, and she wasn’t yours.”

“Aornis had a daughter?” asked Tuesday, who was sharp enough to pick up this stuff two minutes before the rest of us.

“No one ever created a Homo mnemonicus without an intimately known and intimately lost person as a subject. I think Aornis missed Jenny dreadfully and wanted her to live on. The more she created her for you, the more Jenny became alive. But it’s not important. We can remove every single part of her so that all you will retain is a fondness for people named Jenny.”

“You’re that good?” asked Tuesday.

“I’m the second best there’s ever been.”

“It’s a great plan,” said Landen, clapping his hands, “and we all need to get an early night. Big day tomorrow.”

“I was about to say the same thing,” said the Cleaning Lady, glancing at the clock. “It will take a couple of hours, and I have a serious eradication tomorrow. Plus, the trains are not that regular to Whitby these days. Now, if you can all simply relax and hold hands, it will make things easier and none of this will have happened. And don’t worry about the tattoo,” she added to me. “You’ll go into Swindon on Monday and have it removed. You’ll think the scar was a scald that you got three years ago when the handle broke off a pan of water. So if you’ll just empty your minds, Jenny and I can be out of your hair for good and—”

“Wait.”

The Cleaning Lady raised an eyebrow and stared at me.

“I want to keep her.”

“What?” exclaimed Landen.
