Some idle speculation on this semi-plot-hole, which I've seen wondered about at various times:
How did Lily's letter to Sirius, which would have been sent to him while he was living elsewhere than Grimmauld Place (presumably in that flat of his own that he got thanks to Uncle Alphard's money), wind up back in his bedroom for Severus to find, especially given that Sirius went to Azkaban for 12 years?
I was just brainstorming about this while lying in bed last night and wondered if any of the following solutions were plausible as ways for Sirius's stuff to get out of wherever he was living at the time.
1. At the time of PoA we're told that general rumour was Sirius was a Death Eater or other supporter of Voldemort and that was why "he" killed Peter and those Muggles. We know from Karkaroff that not all the DE's knew each other. Could one of the actual DE's somehow gained access to his dwelling and spirited his stuff back to Grimmauld Place (under the misapprehension that Mrs Black, who'd be the only one living there at that point since - canon tells us Regulus is dead; the extra-canonical tapestry drawing tells us Mr Black was too) would give a damn?
2. Scenario similar to the above might also work if it was someone else he knew who was not in the Order and didn't know about it (the Order would probably want to go through his things to make sure there was nothing exposing them, and I don't know if they'd have let this letter and picture go, although maybe the damage was done at that point), and preferred to see his goods returned rather than seized by the Ministry?
3. Could there have been some kind of protective enchantments on his dwelling, similar to those around 12 Grimmauld Place itself, which resulted in everything simply sitting there unfound for 12+ years, and Sirius himself (or someone on his behalf, like Remus) was able to go fetch it sometime after PoA?
