I groaned .An answering groan came from the foot of the bed!Beaded drops of sweat stood upon my forehead.I was more dead than alive.Presently I heard a heavy footstep in my room --the step of elephant,it seemed to me --it was not like anything human.But it was moving from me -there was relief in that.I heard it approach the door-pass out without moving bolt or lock-and wander away among the dismal corridors,straining the floors and joists till they creaked again as it passed - and then silence reigned once more.
