Haunted House Case

This is the most ming boggling case I have ever saw on tv.I like to report about a haunted house case i saw back on television it was on the Discovery Channel the show is called A Haunting it's based on real life encounters with the paranormal this was about a year ago it was about a business man called Edward he had maids in a house now he used to abuse them. This was back in World War 2 now a family moved in to the place. At first the young girl started seeing a guy with a black suit and black hair then the older girl started seeing the apparition too then finally the mother. The family decided to call in some paranormal investigators. The investigators dug up some history about the house that's when they found out a man called Edward and a couple of housemaids used to live in the house as well. They showed a picture of what Edward looked like both the girls and mother both confirmed it was Edward. Now next they decided to take a blank tape and tape recorded into the house they decided to press play and record and live the house to see if anything could be picked up next day they rewind the tape and what they heard shock them first was the sound of them leaving the door shutting then Edwards voice was heard he said ''you didn't tell them did you did you". His voice came on by the way very clear.
