'There is a great big something that lives in my attic.
A shadowed, creeping creature that lurks just out of sight.
I think it followed me here. It makes the same
groaning sound that used to wake me in the middle of
the night. I thought it was just the creaking bones of my
old apartment, but this house is sleek and new, no bones
in sight. But, on the roof of the hallway that connects
my bedroom to the kitchen, there is a trap door. Such
an innocent square that just fails to blend in with the rest
of the ceiling. It is from behind this patch of ceiling that
I sometimes hear thumps and groans. I have not yet had
the courage to open it.' (Introduction)
