Castle of Horror book 3

The two sisters Beatrice la Fleur and la Dolce has been invited to Count Salvador's castle. While they sit in a private part of the castle, they hear a woman scream. The scream was of pure terror, like if the woman was to be tortured and she knew about it. "That scream must have come from upstairs," said the count and stood up from the table. Coming out, there were several people invited to look at the castle. The count asked them from where they heard the scream. One answered, from the stairs, as he pointed at the wide stairs to the upper floors. Another man thought the scream had come from outside the castle. Count Salvador together with the two sisters started to walk up the stairs. Halfway up, they all hard another scream. At this time a woman came out from one of the rooms and said she had been attacked by someone she couldn't see. At the same time, a man was pushed over the safety-guards, and he fell to his death down to the stone floor. "We better call the police," said Salvador and made the call himself.
When the police arrived, a thorough search of the entire upper floor was done, and in one of the room, they found a hidden door. "Can we break it open?" said the police looking at the Count. "Yes of course," answered Salvador. Inside this hidden door they found a wooden chest, Then they all heard the scream again. "Can we open the chest?" asked the police. "Yes of course," answered Salvador, and when they opened the chest they found a full skeleton inside and they all heard the awful scream again, coming from the skeleton. Here started the horror, and the skeleton turns out to be a relative to the Count, an Ann Salvador that had been killed by her brother, a Phillip Salvador that now lived in the castle. He was the one that had thrown the visitor over the safety-guard to his death.
