Averygoodun's Personal File

I think that story came out in bits and pieces throughout several books, and we never learned the entirety of it. I don't think that bit about being forbidden by Dumbledore to tell anyone was ever really explained, as I recall, nor how he managed to keep Snape from telling after he left Hogwarts. Knowing that Dumbledore allowed a werewolf free run of the school would have been of interest to Voldemort, I'd have thought, and it seems like the sort of information that a new Death Eater would offer up as a gift. It would have been handy political info to have, at least. ~shrug~
