From an ITV press release yesterday:
Hugh Fraser, Philip Jackson and Pauline Moran are reunited with David Suchet for Agatha Christie’s The Big Four.
Last seen together in the television adaptation of Agatha Christie’s Evil Under the Sun, Hugh Fraser, Philip Jackson and Pauline Moran are back to reprise their iconic roles as Captain Hastings, Inspector Japp and Miss Lemon alongside David Suchet as the legendary Hercule Poirot in The Big Four.
Adapted by award-winning screenwriter and actor Mark Gatiss and actor Ian Hallard, The Big Four plunges Poirot into a world of global espionage where he uncovers a theatrical tale of murder, secrets, lies and love, set against the backdrop of the impending World War II.
As a deadly game of chess unfolds, Russian grandmaster, Dr Ivan Savaranoff (Michael Culkin) meets a shocking end, sending the public spiralling into panic, as suspicion is cast upon Peace Party stalwarts Abe Ryland (James Carroll Jordan) and Madame Olivier (Patricia Hodge). In one of his toughest challenges yet, Poirot must work out who the good guys are from the bad, as a complex plot sees a host of international figures used like pawns by a gang of dangerous dissidents tagged “The Big Four”.
As the murders and disappearances stack up one by one, Poirot is joined in his investigations by his old friend Japp (Philip Jackson), the dogged journalist Tysoe (Tom Brooke), and struggling actress, Flossie Monro (Sarah Parish), in an attempt to snare the killer and shatter “The Big Four” for good.
