Stabbed in the back
A pieced of lead piping nearby
It should be a simple case...
On a French golf course, a millionaire is found dead on the grounds stabbed in the back. A telegram brings Poirot to France. However he arrives far too late to even meet his client, whose brutally stabbed body now lay face down on a golf course, does not help Poirot at all.
But why is the dead man wearing his son's overcoat? And who was the love-letter in the pocket for? Before Poirot can answer these questions, the case is turned upside down by a massive discovery.
