Deception in L’Amour, from Larry Williams
I have been reading a series of Louis L'Amour short stories and one of the driving themes behind them is deception.
Texas Rangers don't come to town dressed up like Texas Rangers but as bums, bad guys dress up like good guys.
His work is filled full of false flags being used.
I thought this was a very cool use of deception as well: "man who killed Osama Bin Laden reflects 5 years later"
