<big><center>Mary Higgins Clark takes you deep into the mysteries of the human mind?where memories may be the most dangerous things of all.</center></big>Kay Lansing grew up in Englewood, New Jersey, daughter of the landscaper to the wealthy and powerful Carrington family. One day, accompanying her father to work, six-year-old Kay overhears a quarrel between a man and a woman that ends with the man's caustic response: "I heard that song before." That same evening, young Peter Carrington drives the nineteen-year-old daughter of neighbors home from a formal dinner dance at the Carrington estate, but she is not in her room the next morning and is never seen or heard from again. Decades later, a cloud of suspicion hangs over Peter, not only for his neighbor's disappearance but also for the subsequent drowning death of his own pregnant wife in their swimming pool.
