"And, uh, I guess don't kidnap me and do mad wizard experiments on me, because it makes Feral mad, but I don't think you were going to anyway." Pause. "I have their notes though."

"I would like to read their notes," says Sherlock.

"But not do mad science to you. Because that would be wrong," says Tony.

Bella fetches out the notes and offers them to Sherlock. "Yeah. But as long as they already did the mad science I'm glad I get to know what they found out. It's better than not."

Bella is immune to quite a lot of things, invariably "responds in a manner consistent with awareness of intrusion, including spells cast silently and out of sight", and appears to "instantly and instinctively, but with more negative affect, respond to mind-affecting magic in the way the most highly trained Occlumenses might".

"The Imperius Curse?" says Sherlock.

"They tried it. It didn't hurt nearly so much as some of the others, actually, it was more like accidentally putting my face in a spiderweb than anything."

"Do you think the sensation correlates with anything about the spell?"

"...Maybe. All the spells were definitely the same every time, I'd recognize them if someone did them again. I don't know enough about most of these spells. I'm going to look them all up when I get back to school. They didn't write down anything I said about how they felt but I did, so I have all of that, here -" She produces a separate page of notes, which has a brief paragraph of recollections about the synaesthetic sensations corresponding to each attack, including the spiderweb Imperius, burning Confundus, spiky-stinging Legilimency, and battering Memory Charm.

Sherlock compares these sets of notes in fascination.

"At least it was interesting mad science."

"Yes," says Sherlock.

"I don't know how they found out I'm an Occlumens but I guess I did throw off that Memory Charm in front of an awful lot of people, and then more people would've found out when your mom was trying to get the teacher fired."

"Also true," says Sherlock. "But I would like to know with more certainty. What else can you tell me about them?"

"I didn't see them very clearly because by the time my eyes were all better they were both dead. One of them said his name was Preston and the other one was Martinez. He could've been lying, but he seemed really scared of Feral. And the house was in Nashville and they were both white people with brown hair. Feral got a better look at their faces."

"Perhaps I'll have to ask Feral, then," says Sherlock. "What did you notice about the house?"

"It was one story, and the medicine cabinet had wizard eye drops in it that I thought about trying before your mom offered to take me to a healer. The room I was in was mostly white, even the furniture, kind of like an interior decorating magazine room, but the rest of it looked pretty normal. Uh, there was a glass on a table in the white room, Feral charmed water into it to give me when I asked him, before Martinez came back. Preston said something about Martinez having a car phone but we didn't wind up using it and I don't think there was another phone in the house."

"Nothing useful springs to mind out of that," he murmurs.

Bella closes her eyes and tries to remember. "The chair probably would've been comfy if I hadn't been stuck to it - there were carpets everywhere I saw except the bathroom - it must've been pretty well soundproof because they didn't hear me and Feral talking."

"Hmmm."

"And they must've been waiting for me because they got me right after the bus drove off, does that help?"

"Somewhat, yes," he says. "Still nothing concrete."

"Your mom might be able to Apparate you there, if that's the sort of thing she would do."

"I will ask."
