I have a little mouse too inside an unreachable wood-walled section of the house (he's between the concrete wall and the wood wall) and digs on the wood every night. I'm always scared off when I'm walking by his home at night and I suddenly hear the digging and scratching. Spooky mouse.
I've seen his eyes once and he's really cute, although my family begs to differ and has tried to feed him poison over all kinds of meals and set mouse traps everywhere. However, it has not fallen to the bait and the fight still goes on. I might have to follow your advice and burn down my house.
