Ardath soon encounters Helen Grosvenor (Zita Johann), a half-Egyptian woman bearing a striking resemblance to the princess. Believing her to be Anck-su-namun's reincarnation, he attempts to kill her, with the intention of mummifying her, resurrecting her, and finally making her his immortal bride. Helen is rescued when she remembers her ancestral past life and prays to the goddess Isis to come to her aid. The statue of Isis raises its arm and emits a flash that sets the Scroll of Thoth on fire. This breaks the spell that had given Imhotep his immortality, causing him to crumble to dust. At the urging of Dr. Muller, Frank calls Helen back to the world of the living while the Scroll of Thoth continues to burn.
