midnight
haunt the place where the body lay ! So I haunted the museum night after night . I even got other spirits to help me . But it did no good , for nobody ever came to the museum at midnight . Then it occurred to me to come over the way and haunt this place a little . I felt that if I ever got a hearing I must succeed , for I had the most efficient company that perdition could furnish . Night after night we have shivered around through these mildewed halls , dragging chains , groaning , whispering , tramping up and down stairs , till , to tell you the truth , I am almost worn out .
