Letter to Remus: Number 58

It all starts with Sirius not being able to bloody sleep again, so it's back to the leather notebook at the bottom of his trunk (secret pocket, of course-you can never be too careful with Prongs around) and time to write another letter to Remus-number 58, in fact. Except this time it's a rambling-sort of confession. A love declaration, if you will, and though it's definitely not the first, it's the longest he's ever written. The first time he's ever outright explained it all. And the worst thing happens: someone, The Someone Who Was Never Supposed to Find It, stumbles across it while looking for a jumper, and writes back, and James Bloody Potter gets involved, and it all goes to shit.
