In Agatha Christie's 'The Clocks,' a young typist arrives for a job at the home of a blind woman, only to find a dead man surrounded by four clocks stopped at 4:13. The blind homeowner denies hiring her, knowing the victim, or owning the clocks. The police are baffled by the seemingly motiveless crime and the bizarre staging. The case eventually reaches Hercule Poirot, who, mostly from his armchair, uses his 'little grey cells' to unravel a complex plot of deception, espionage, and hidden identities, proving that even the most meticulous crime has a flaw.
