by Agatha Christie

 From seat No.9, Hercule Poirot was ideally placed to observe his fellow air passengers. Over to his right sat a pretty young woman, clearly infatuated with the man opposite; ahead, in seat No.13, sat a Countess with a poorly-concealed cocaine habit; across the gangway in seat No.8, a detective writer was being troubled by an aggressive wasp. What Poirot did not yet realize was that behind him, in seat No.2, sat the slumped, lifeless body of a woman.

This is the very first Poirot/Hastings story. Set in 1916, we meet Captain Hastings as he is invalided out of the Great War and goes to convalesce at Styles Court, the family home of his great friend, John Cavendish. By an extraordinary coincidence, billeted in the village is a brilliant little retired detective with an egg-shaped head, who made a considerable impression on the Captain when he was in Belgium. Styles is not a happy household and in the blistering summer heat, tensions mount. Even so, the tragic murder, which occurs is not expected. The entire family is drawn into the case but with their reluctant permission, Hastings calls upon the services of the diminutive Belgian.

A full-cast BBC Radio 4 dramatisation of an Agatha Christie story.
On a flight from Le Bourget to Croydon, on which Hercule Poirot is an apprehensive passenger, a woman is found dead. A doctor on board is inclined to put it down to a wasp-sting, but Poirot suspects that a poisoned dart is the real cause - and, perhaps rather too conveniently, a blow pipe is dicovered stuffed down the back of his seat. Clearly the murder can only have been committed by one of the passengers or crew on the plane. But which one? Poirot, Japp and M. Fournier of the Surete will make their way through shoals of red herrings before reaching an utterly unexpected conclusion...

On the elegant, plush Orient Express — the train from Istanbul to Paris — Ratchett, an imperious millionaire gangster, killer, kidnapper, and child abuser, confronts Inspector Hercule Poirot and offers the little Belgian $20,000 if he will help him stay alive. Poirot declines, adding, "I do not like your face, Monsieur." Later that evening, as the train sits halted and snowbound, Ratchett is found dead inside a room locked from the inside, a victim of multiple stab wounds. Clearly, the clever, ruthless killer is still on board the train. Detective Poirot must find the killer of the much-hated millionaire among thirteen suspects, each with a compelling reason to kill Ratchett.
