Murder on the Links

Belgian detective Hercule Poirot is summoned to France after receiving a distressing letter with a urgent cry for help. Upon his arrival in Merlinville-sur-Mer, the investigator finds the man who penned the letter, the South American millionaire Monsieur Renauld, stabbed to death and his body flung into a freshly dug open grave on the golf course adjoining the property. Meanwhile the millionaire's wife is found bound and gagged in her room. Apparently, it seems that Renauld and his wife were victims of a failed break-in, resulting in Renauld's kidnapping and death.
