I'm making up for it now, I suppose. No shortage of museums in Boston... and though only three are art museums, two of the three are fantastic, as is the one in Salem.
Actually, the only thing that wasn't stolen at the Louvre's Apollo Gallery is the Regent Diamond, figure no one would take it because something to do with a curse.
I've also found that the two thieves were leaving for Algeria, thanks of a trace of DNA evidence recovered from a helmet and their past in burglary cases according to the police.
