Murder on the Links

"For God's sake, come!" Unfortunately, by the time Hercule Poirot receives Monsieur Renauld's urgent plea, the millionaire is already dead - stabbed in the back, lying in a freshly dug grave on the golf course of his adjoining Merlinville estate. There's no lack of suspects: his wife, whose dagger served as the weapon; his embittered son; his mistress. Each of them feels deserving of the dead man's fortune. The police think they've found the culprit. Poirot has his doubts. A second murder proves him right.
