Wisdom of Father Brown [PDF ebook] 

The star of these stories is Father Brown, a character created by writer G. K. Chesterton.

The stories included here are The Absence of Mr Glass, The Paradise of Thieves, The Duel of Dr Hirsch, The Man in the Passage, The Mistake of the Machine, The Head of Caesar, The Purple Wig, The Perishing of the Pendragons, The God of the Gongs, The Salad of Colonel Cray, The Strange Crime of John Boulnois, and The Fairy Tale of Father Brown.
