Burn the book.

While she felt sorry for the spirit and its unfinished business, she wasn't about to fuck a ghost. She had dealt with hundreds, if not thousands of them, tragedy was part of the job.

She pulled a lighter from one of her pockets and ignited a corner of the notebook. The ghost appeared, a small muscular man fully nude, and Anna couldn't help but stare at his massive member for a moment with a pang of regret.
