S02E05 - Double Sin

Poirot, as a result of spreading fame, has been overworked and Hastings suggests he rests by accompanying him on a week's holiday to the south Devon coastal resort of Ebermouth. On their fourth day there, Poirot receives a note from the theatrical agent Joseph Aarons who asks him to travel to Charlock Bay on the north Devon coast as he needs to consult him on a matter. The two are planning to go by train but Hastings sees a notice for a motor bus tour from the one resort to the other which will save time on changing trains. Poirot reluctantly agrees, afraid of the uncertain English climate and the drafts of air which will invade the bus. They book their tickets at the office of the company concerned where Hastings is taken with another customer, an auburn-haired girl, whereas Poirot is intrigued by a young man who is attempting to grow a feeble moustache.
