  "description": "Tym razem przeciwnikiem Herkulesa Poirota jest złodziej, który wykrada wzór groźnego materiału wybuchowego. Jej wynalazca, sir Claud Amory, zostaje otruty w swojej rezydencji, a ujawnienie rodzinnych sekretów grozi skandalem. Czy rzeczywiście kobiety częściej używają trucizny, a mordercy są zbyt pewni siebie? I co wspólnego ma praca pokojówki z pracą detektywa? Uwaga rozdrażnionego kapitana Hastingsa nieoczekiwanie pomoże uporządkować wszystkie elementy zagadki.",
