David Suchet is a pitch-perfect Poirot in these gorgeously filmed adaptations of Agatha Christie's mysteries. The diminuitive detective cracks cases with a sharp mind, dry wit, and help from his friends, including Captain Hastings (Hugh Fraser, Sharpe), Inspector Japp (Philip Jackson, Boomers, The Good Karma Hospital), and Ariadne Oliver (Zoe Wanamaker, My Family, Mr. Selfridge).
