"Precisely," he agrees. Giving nothing away, "Why would they be?"
"Ghosts can't hold quills. Granted that they'd be at the mercy of a scribe, but unless they were too stupid to--I suppose one can't say too stupid to live, but in any case, unless they were too stupid to justify their allotment of ectoplasm, they'd be dealing with the League for Magical History, and the LMH is very strict about things like that."
