G. K. Chesterton 
Man Who Knew Too Much [PDF ebook] 

The Man Who Knew Too Much is a collection of short stories by British writer Gilbert K. Chesterton, featuring his detective Horne Fisher. From the upper-classes himself, Fisher has a unique insight into political power–a position which complicates his investigations when they approach the higher levels of corrupt government. Chesterton’s witty, paradoxical work, published in 1922, gives an interesting view of the pre-Great War era.
