The Cradle Will Fall by Mary Higgins Clark

A minor road accident landed county prosecutor Katie DeMaio in Westlake Hospital. That night, from her window, she thought she saw a man load a woman’s body into the trunk of a car…or was it just a sleeping pill induced nightmare? At work the next day, Katie began investigating a suicide that looked more like murder. Initial evidence pointed elsewhere, but medical examiner Richard Carroll saw a trail leading to Dr. Edgar Highley. He suspected that the famous doctor’s work “curing” infertile women was more than controversial — that it was deceitful, depraved, and often deadly. But before Richard could tell Katie his fears, she left the office for the weekend and an appointment for routine surgery…in Dr. Highley’s operating room.
