THE MURDER ON THE LINKS

When Poirot arrives in France, following an urgent appeal for help, he finds he is too late. His client, a South American millionaire, has been 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. Her wrists are badly cut and she seems to be in shock, but she agrees to speak to Poirot. She tells him that they were attacked by thugs who tied her up and forced her husband to leave the house, dressed only in his underwear, before brutally killing him. Poirot is not sure whether to believe her story
