David Suchet ("Henry VIII," "The Way We Live Now") returns to his signature role as suave Belgian supersleuth Hercule Poirot in two new mysteries based on the novels by Agatha Christie. Whether he's on holiday abroad, taking a countryside break or simply going about his business near his central London home, Poirot finds himself exercising his "little grey cells" by helping police investigate crimes and murders, whether they ask for his help or not. Poirot tackles an intriguing and dangerous murder case involving international espionage, a Middle-Eastern revolution and a missing princess. The surviving heir to a Middle-Eastern throne is hidden away from revolutionaries in a small English girl's school, but when - one by one - teachers are found murdered, it seems the school may not be such a haven for the princess after all.
