Write a page-turning, fast-paced thriller story in third-person narrative about a young, newly-married woman who becomes increasingly convinced that her charming, next-door neighbor is a ruthless serial killer – and through a series of daring, suspenseful encounters and unexpected twists, she must gather enough evidence to prove his guilt before he strikes again. Ensure that the story is full of tension, suspense, and mystery, with gritty, vivid descriptions of the killer's brutal crimes and the woman's brave attempts to outsmart him. Use foreshadowing, red herrings, and unexpected plot twists to keep the reader on the edge of their seat, and make sure the ending is satisfyingly surprising and clever. Your word count should be at least 2,500 words.
