The Power and the Glory and A Gun for Sale are two Graham Greene novels.
Yes, The Battle of Britain was won on benzedrine --Graham Greene.
Very different from each other, I read these one after the other. When encountering this kind of writing, it really puts film in its place, that of being so very subservient to writing (and essentially dependent upon it). That much, most, and multiple times Greene's writing has been made into film is not the point at all, but rather that the writing is so primary, commanding attention.
A Gun For Sale
We start out with the protagonist a professional killer with a hare-lip. Very strange since that is so very conspicuous a disfigurement, but it underscores how very good and careful is this hired gun.
Then we move on to an actress/singer/revue dancer whose fiance is a police detective from Scotland Yard.
Greene is terribly brilliant at weaving these stories together, how they encounter each other, and what makes them seethe with strength and vulnerabilities.
The Power and the Glory
In turns exhausting and inspiring, the main character is throughout much of the novel literally starving, walking with shoes that have no soles on his feet, and traveling through impoverished lands, hunted, protected, and betrayed by others and by himself, a death sentence upon him. How he ultimately comes to grips with his own internal struggle is an epic ordeal.
Fantastic books, the two of them. I've started in on The Ministry of Fear which is equally as compelling so far.
