I think that's a reasonable assumption. It is a very desirable item. Any idea on where we might find that vault?
That does explain away quite a few things. So you had Hermione's memories, the insight might be helpful to our work. I had heard about the map from the memories I recieved. I'm reasonably certain I know the password. People love things to come full circle, perhaps starting with the connection to Filtch is the way to go.
