Mrs. McGinty's dead: ‘Mrs McGinty’s dead!’ ‘How did she die?’ ‘Down on one knee, just like I!’ The old children’s game now seemed rather tasteless. The real Mrs McGinty was killed by a crushing blow to the back of the head and her pitifully small savings were stolen. Suspicion falls immediately on her lodger, hard up and out of a job. Hercule Poirot has other ideas – unaware that his own life is now in great danger.

Labours of Hercules: At a dinner party, another guest compares the labors of Poirot to those of Hercules, and the little Belgian is not amused. He has already decided to retire, but makes up his mind to take on 12 great cases - each somehow reflecting the labors accomplished by Hercules - as a farewell to crime solving.
