Watch Masterpiece Mystery online: Episode 2 Hercule Poirot. Series XI: The Clocks

Hercule Poirot is summoned to Dover to investigate something even more sinister than the British Navy's suspicion of espionage: murder! -- With England on the brink of war with Germany, Hercule Poirot is summoned to Dover to investigate something even more sinister than the British Navy's suspicion of espionage: murder! Tom Burke (Dracula), Anna Massey (Tess of d'Urbervilles) and Lesley Sharp (The Diary of Anne Frank) guest star. -- A lovely young stenographer, Sheila Webb, is greeted at a job not by her client but by an eerie assembly of clocks all frozen at the precise same moment in time and, behind the couch where she sits waiting, a corpse. Horrified, she scrambles screaming into the street, straight into the arms of Naval Lieutenant Colin Race. In Race, she finds a protector who takes her story to Hercule Poirot, and together they set about exonerating her, all the while trying to unearth a German mole who masterminded Race's botched spy mission at Dover Castle. But when a second murder is discovered, the mystery becomes more "dagger" than "cloak" and the evidence mounts against Sheila. Faced with enduring a pint of beer, the rubbing of cats against his legs, and being mistaken for a Frenchman, will Poirot prevail in revealing the killer and the mole? Joined by Tom Burke (Dracula), David Suchet stars as Hercule Poirot in this adaptation of the novel by Agatha Christie.
