Bethilda Bagshot is a seemingly harmless old woman who lives in the village of Little Hangleton, near the Riddle House. She is known for writing a book called "A History of Magic."
Here's what you need to know about Bethilda:
* A Deceitful Cover: Bethilda is actually not who she appears to be. She was murdered by Voldemort's snake, Nagini, who disguised herself as Bethilda. Voldemort used this as a way to enter the Riddle House and obtain a Horcrux hidden there.
* Importance to the Plot: Bethilda's death is significant because it marks the beginning of Harry, Ron, and Hermione's search for Voldemort's Horcruxes. It leads them to the Riddle House, where they learn more about Voldemort's past and ultimately discover the locket Horcrux.
* Connection to Voldemort: Bethilda was actually a distant relative of Voldemort and knew him from his childhood. She is connected to Voldemort's past and is a testament to the dark path he chose.
While Bethilda might initially seem like a harmless old woman, she is actually a key player in the events of Deathly Hallows. Her death, and the deception surrounding it, serve as a crucial turning point in the fight against Voldemort.
