You sit up with some difficulty and glance around. To the right
of you, rats are fighting over a piece of indistinct rubbish. The
ground in this alley is covered with shards of broken glass. You feel
like you're about to vomit but you don't. It seems there is nothing in
your stomach to puke out. All of a sudden, you notice a door in the
wall facing you. Funny, you think, "I never noticed it there
before."
