Sorry about the extended silence, the police have been giving me shit about that box in Grandpa's attic. This one guy, Inspector Calston or something, his eyes didn't look right. Almost kind of like how an animal's eyes shine in the moonlight. Like a cat's. And he only seems to work the graveyard shift.
Good news, though, I got a lead on Adam! An anonymous tipper told me he saw a kind like that walking with someone dressed like a friar later that same year, so my search continues!
