Hercule Poirot rushes to France in response to an urgent and cryptic plea from a client, but the Belgian detective arrives just too late. He had been stabbed multiple times with a letter opener and left in a freshly dug grave. The victim lay face down in a grave located within a golf course. He was wearing his sonâ€™s overcoat and a love letter within. His wife had reported that masked men had abducted him from their home in the dead of the night. The mystery thickens when another corpse is found, stabbed with the same weapon, in the same way. While the local authorities pursue the false leads suggested by the evidence, Poirot fights to unravel the mystery behind â€˜The Murder on the Linksâ€™. He relies instead upon his famous 'little grey cells' to cut through the confusion and untangle a story of blackmail, forbidden love and a long-buried secret.
