Have you ever wondered what you might find in your attic, or someone else’s attic? What about hidden in a wall after taking off the electrical socket plate? I always thought it would be fun to find an old letter from a previous occupant.
Your character is rummaging through old boxes in the attic and comes across a box of letters. There is something revealed in one of the letters that they can’t keep to themself, at least they don’t think they should. It could be a confession of murder, adoption, or just about anything. Play around with it and see what you can come up with. Have fun!
