A woman dressed as Little Red Riding Hood, is found dead with gruesome claw marks on her face.
The victim is identified as a high-powered attorney named Amy Morgan. Her sister, Leslie, and brother-in-law, Darren, have no idea why she would be dressed like Little Red Riding Hood. It turns out that Amy recently withdrew $50,605 from her bank account.
Another murder victim is found in the park. This woman is dressed as Snow White. Snow White’s real name is Kristina Curtis. Just like Amy Morgan, this second woman was drugged before being killed. Kristina’s husband says that his wife was an art gallery worker who skipped a lunch date with him on the same day Amy was unaccounted for. This was just before she was killed. She also withdrew the exact same amount of cash as the first victim.
The fairy tale costumes worn by the two victims came from the same place. A third outfit was also ordered. This one is for Sleeping Beauty. The items are traced to an elderly woman who collects dolls. The elderly woman receives lots of packages that are left in her lobby, but she never ordered any fairy tale costumes.
The third target of the fairy tale killer is Charlotte Boyd. Beckett and Castle rush to her apartment and find her on the bed in full Sleeping Beauty attire. She’s still alive. Castle and Beckett banter about Castle being “Prince Charming”.
An old photo featuring all three victims is found at Charlotte’s place. They are all dressed as fairy tale characters. The date stamp on the photo reads 05/06/05 which corresponds with the amount of money they all withdrew. There’s a note on the back of the photo. It reads: Who’s the guiltiest of them all? If you pay you’ll live to see another day.”
A young man in the photo, Owen Thomas, was killed on the date the photo was taken. He died after a hit-and-run accident.
Charlotte aka as Sleepy Beauty, wakes up and discusses the night she and her friends attended a rave. They were all pretty messed up. They left Owen by the side of the road when he started having hallucinations. The three girls made a pact to never say anything about that night when Owen was reported dead the next day.
The team learns that Owen’s older brother is married to Amy Morgan’s sister, Leslie. Darren had the pictures printed after finding an old roll of film. He realized the girls left Owen by the side of the road the night he was killed. He wanted them to pay for what they did. That’s why hatched the blackmail plot, but swears he didn’t kill anyone.
Martha is having a staged reading of her new one-woman play, How to Do it All… Without Even Trying. Catchy. As Castle helps Martha with her costume, something about her bow has him thinking they arrested the wrong man.
Castle and Beckett visit Charlotte in the hospital to get the real story of the night Owen Thomas died. The three girls were in the car that killed him. Charlotte claims Amy was driving. Castle knows that the killer tied all three bows on the costumes of the victims. Only Charlotte’s bow looked like it was self-tied. It turns out Charlotte was the one who hit Owen and murdered her former friends when the secret looked like it was about to be revealed. Case closed.
Castle and Beckett catch an encore performance of Martha’s staged reading. She tells the story of how she gave up the role of a lifetime on Broadway to fulfill an even greater role as a mother. It’s a sweet moment that doesn’t last long once Martha begins to delve into her son’s story. Castle is, of course, mortified. Thankfully, Beckett is there to playfully grab his hand in support.
