He stalks you as you wander through the entrance of the underground. You pay for your ticket, aware of him lurking over your shoulder. You try to ignore him, but this is an impossible task.
   You tell your best friend he is there, but your best friend can't see him, so he doesn't believe you.
   He remains to linger as you wait for your train. In your mind you feel you're going mad; he can't really be there, can he? You begin to question facts you know to be true, like there are no such things as ghosts. Are there? As you board the train, he cannot follow you, and you feel safe once more. Or so you think. He is waiting for you the moment you step off again.
   You beg your best friend to admit he can see the crossing keeper, but your best friend still denies all knowledge.
   You see past travellers and their ends. Again, you plead with your best frined to see him. But he still can't.
   You are trapped, deep underground. Alone.
   Everything goes dark in a desolate tube station.
   The crossing keeper has found you.
   His heels click against the marble floor.
   You feel his breath on your neck.
   " 'Scuse me, sir, do you know where the toilets are?"
