I owned and inhabited a very big house in town, and I didn´t yet know all the different parts. So I took a walk through it and discovered, mainly in the cellar, several rooms about which I knew nothing and even exits were not locked and some had no locks at all. Moreover, there were some sinister figures that could have sneaked in...who were they? did I know them? I was afraid, I walked along toward the exit, but I couldn´t remember the way.
