He's here, sometimes, just like he can appear anywhere in the city, sometimes flickering like an old movie or a low quality hologram, other times looking so real you think he's solid unless you get too close and put a hand through him. But this is the place you can find him at most reliably; every year, like clockwork, he appears in this alleyway and lays down two ghost roses so real that you can smell, if not touch, them.
He appears other places- the rooftops, even if hardly anybody ever actually sees more of him than a movement out of the corner of their eye when he's up there; where violent crimes are being committed, scaring the hell out of the criminals even though he can do nothing physically; Arkham Asylum, whose inmates are pleased to see him as confirmation that he's still around; and the police station, as silent as ever but willing to lead the police to crimes and criminals.
He's never seen in anything other than the costume. Theories abound about this, but only a few are strongly held- that he never had another identity. That he gave his life so completely to fighting crime that his other identity didn't make enough of an impression on him to make an appearance on his ghost. That with his death he forgot everything except for being Batman.
