Dumbledore Suspects Nagini is a Horcrux

PAGES: 505-507

Dumbledore reveals his suspicion that Lord Voldemort's snake, Nagini, is one of the Mystery - Lord Voldemort's Horcruxes. He believes that Lord Voldemort created Nagini as a Horcrux after failing to kill Harry as a child, using her to preserve part of his soul. However, this act comes with great risk since a living creature can act independently.
