The Return of the Marauders

Professor Snape thought this year was off to a bad start anyway, what with Remus Lupin coming to teach at Hogwarts (and getting the job HE wanted and deserved!); but when stupid and familiar pranks start targeting him, he'd have no choice but to believe he's either gone mad… Or that they have come back! Semi Sirius—I mean serious story. Set during the Prisoner of Azkaban.
