Woman on an island, day 22

I slowly walk closer to the house, looking for any signs of life. "Is anyone there?" I shout but receive no response. I try to look through the window but it's too dark too see anything. I slowly open the door...hmm this lock looks new. I fumble for my lighter and soon the little flame chases away some of the shadows. This looks like it was some sort of storage space,it's full of now empty boxes and crates. I move cautiously through the rooms, my spear at the ready. I pass a kitchen which seems in remarkably good use, nothing in the cupboards though. I eventually reach a closed and locked door, this should not stop me as I pull out a small piece of wire from my bag. I manage to pick the lock (who knew Juvenile detention would be good for something?) and push the door open. It's a bedroom and someone has recently slept in this bed! but who? I look around for any clues then I notice a painting on the wall. It's a man with tattered clothes and a wild bushy beard, I look closer to see the signature: John Henry Moore. Who are you and where did you come from? I straighten the picture when something falls out from behind it....it's a piece of paper!
