Skulduggery shrugs.] Anywhere in the Sector not already on that list. The Metalworkers own most of it, and there's no pattern I can see. I don't think the thief has one in mind, actually; I think he's picking likely-looking targets at random. The question is what makes them likely-looking.

Something else that reacts with the material? Is that how your powers work?

[It's a strangely specific suggestion to come up with otherwise.]
