Rex is an old man who has a large estate. He has relatives that have not talked to him for years and he tells people they are dead. Everyone that bothers with Rex likes him. He is kind of weird and he talks people into doing things they would not do.
He has a niece named Faith that he just recently invited over to meet him. Everyone is surprised that his niece shows up, he has been telling everyone that his niece and family are dead and died in a airplane crash 4 years ago. Faith said they had been corresponding for a couple of months and was excited to meet him. Her mother had not talked with Rex for over 40 years.Faith walked around the house and saw pictures of her and her family on tables and did not know how Rex got them, he did not get them from her.
Miles a man and friend of Rex is at the house. Miles is like a landscaper. He checked the house and the property but Rex cannot be found. Faith stays over night in the house while waiting for Rex to show up. Miles is angry because is name is on the Will and here is Faith the niece alive.
Rex's body turns up in a river the next day.
Barnaby goes to talk to Rex's lawyer. He finds out that his last will was about 12 months before his death and Faith will get his estate. That is before 3 other people who did work for Rex for free show up with a Will signed by Rex, all valid giving them the inheritance solely to each one of them.
There are many mysteries and suspects who have good reason to kill Rex. and other deaths in this video, it is one of the better ones. "The Animal Within" has a great ending and I enjoyed this very much.
