The Dying Wish

Starts off in book three. Lupin is a good werewolf, takes his potion and stays away. Snape also doesn't show up. Sirius stands alone against Pettigrew and three teenagers, one of which very much wants to kill him. Sirius is more than willing to allow this – but on his own terms. And first he has to kill a certain rat… Sirius B., Harry P. Some violence and angst. Rated M for safety.
