Mrs. McGinty's Dead (Hercule Poirot, #32)
'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.
