In the English village of Kings Abbout, Mrs. Ferrars—rich widow, rumored to have killed her husband—dies of an overdose of veronal. Everyone thinks she committed suicide. But soon after her, Roger Eckroyd—the manufacturer planning to marry Mrs. Ferrars—dies, and his stepson Ralph Peyton disappears without a trace. Too many deaths for one small village. Hercule Poirot takes up the investigation again.
