Aradia had tuned Faust's rambling out when he started describing the man's sweater, of all things - the basic picture was enough to help narrow down whatever leads they manage to turn up. Which is about as far as her detecting skills normally stretch but the rest can't be that hard to pick up as they go, right?

The fact that there's already the beginnings of A Plan only fuels the younger ghost's enthusiasm, her prior worry over Clara's unease already forgotten. Between the two of them, they're bound to find something worthwhile, especially when they can go places that humans like Faust can't. "And if that fails it's not like we can't poke around town ourselves. Or start questioning people. It's as good a place to start as any, and that way we can find out where to go next."

This was going to be fun. London beware, the ghosts are loose.
