Shabby and lumbering, with a face like a Norfolk dumpling, Father Brown makes for an improbable super-sleuth.

The Innocence of Father Brown Starts at Chapter 1, The Wisdom of Father Brown Starts at Chapter 13.

Even the colonel’s daughter, Lettice, desperate for money, says, “If only father would be decent and die, I’d be all right.” These complexities lead to any number of dead ends for investigators. The only one able to see through the blinds and obscurities is Miss Marple, an elderly but sharp-eyed spinster.
