this is one of my favorite kate bush songs, about bess houdini's attempts to contact her dead husband (harry houdini) through seances and mediums with a pre-arranged code -- and her conflicting desires: a wish to actually be able to talk to him, and a wish to help debunk these fraudsters.
anyway someone has made an amazing lyric video that captures the spirit of the song beautifully:
