In a perfectly punctual Swiss hotel in Lucerne, a millionaire’s cat vanishes without a sound—and with it a tiny ribbon-tied key to a jewel casket—pulling the Belgian Detective and his loyal companion into a light, closed-circle puzzle of immaculate timetables, fussy guests, and staff who hide behind “good hygiene” and louder complaints; as whispered suspicions multiply and an inconveniently well-fed Minou reappears, Poirot follows routine, appetite, and opportunity to expose a thief who counted on order to mask disorder; The Collar of Intrigue is an original Golden Age–style cozy mystery about misdirection, petty greed, and the quiet power of noticing what everyone else dismisses. FOR LISTENERS This is an original Golden Age–style mystery presented as a respectful homage to classic detective fiction. All characters and events in this story are fictional. No affiliation, endorsement, or official connection is implied. QUESTION FOR THE COMMENTS In a mystery with no violence, what catches a culprit faster: motive, opportunity, or the small habit they can’t help repeating?
