‘Castle’ Season 5 episode 20 “The fast and the Furriest” aired Monday March 15, 2013. The suspect of the murder, at least according to Castle is Big Foot.
Man or Beast
A woman is shoved out of a car at a hospital and she has obviously been attacked, but the question is by what. When Beckett asks the ME what was used to attack her and destroy her face, the ME says he’ll need to do the full autopsy to know more. A witness says a blue sedan was used to leave her at the hospital. She is identified as Anne Cardinal and they find she has a PhD in evolutionary biology, and worked at Haven House.
Big Foot did it
After a visit to Haven House, Beckett and Castle discover Anne was picked up at nearby ally. They visit the ally to find lots of blood and large footprints. Castle then suggests Big Foot killed Anne, Beckett as usual plays the sound mind and tells Castle to get real. They visit Dr Meeks, who is the authority on Big Foot, since Anne’s last call was to him. They show him a sketch of the man who she was seen arguing with, and Dr. Meeks and his wife identify Chase Diggins, an Australian adventurer who is violent and unstable.
Big Foot Encounter
The ME finds she swallowed a pendent, and shards of glass in Anne’s hair from a camera. The pendent they learn, belonged to Anne’s former roommate who died a year ago. Anne was looking into her roommate’s death, and the prime suspect was her roommate’s boyfriend. They locate her old boyfriend and find that Anne was helping to clear his name.
They locate the footage from the camera and find that Anne wasn’t killed in the ally, but in the woods. Beckett and Castle go to investigate they fall down a hole. Castle helps Beckett out of the hole so she can go back to the car for rope. While she’s getting the rope Big Foot comes along. Beckett hears Castle shouting for help and runs back to the hole. Beckett threatens to shoot the Big Foot until he falls into the hole with Castle when he takes off his mask and suddenly Big Foot is really Dr Meeks.
A website has offered a large monetary reward for proof of Big Foot so Dr. Meeks was just trying to get the evidence for the reward. When they talk to Dr. Meeks again they realize who killed both Anne and her former roommate.
Mystery on the Side
Who is stealing Castle’s food? Turns out Alexis made a donation to a friend who is working to plant bamboo trees to help clean the air. She didn’t want the speech from Castle about being careful of who she gives money too so they don’t think they can take advantage of her.
