When Mathew Hansen first heard the disembodied voice of a woman through the wall of his new London flat, he thought he imagined it. Mind playing tricks, in a flat that settled and creaked like an old woman. Or maybe too much booze fuelling his nightmares.The voice couldn’t be real; just the wind, moving around the old Victorian house.Besides, his bangable neighbour Amanda couldn’t hear the strange chanting sounds. She was just messing with him when she said she did. A little payback for sleeping with her and never calling her back.It must be his imagination.Right?
