Write a suspenseful novel depicting the journey of a successful businesswoman who gets stuck in an elevator with a notorious serial killer, and describe how she uses her intellect and quick thinking to outwit him and save herself before it's too late. Ensure that the story is paced well, the characters are well-developed, and the setting is atmospheric and claustrophobic to heighten the tension. Additionally, use vivid language and descriptive imagery to create a palpable sense of fear and terror, and deliver a satisfying and surprising conclusion that leaves readers on the edge of their seats.
