I have a question about Horcruxes.
Actually, I have several, but just this one for now (story spoilers, you know):

If someone had split their soul and lost a bit of it to a Horcrux, would the Healers at St. Mungo's be able to tell?

Interesting question, yes? What do you think? I'm inclined to say 'no', since it seems very inexact, but that may be because that's just how I want it to work for the plot bunny I've been nursing for months and months.

Thanks!
