n route to the train station to attend a disarmament conference in Paris, the Prime Minister's car is attacked by what the press describe as ruffians. The PM is slightly injured and does make it across the Channel to French soil, but never arrives in Paris. Poirot is called in by senior government officials as it appears the Prime Minister has been kidnapped. He soon comes to the conclusion however that the evidence from the first attack doesn't quite add up and all is not what it seems.
