Well - it turns out Bart was high up in the world of intelligence and espionage as well. He wrote a book covering the use of deception, outs and double-crosses in espionage:

It looks like an interesting book and I am going to check it out some time soon. I just hope it is not too dry and academic. Anyway - I thought others might be interested in this book. And I am curious if anyone here has read it as well?
Here is the amazon description of the book. You can see why I thought it might appeal to magicians. And equally - Bart's background in magic shines through as well.
This title combines two of spymaster Barton Whaley's most potent analyses of the craft: Turnabout: Crafting the Double-Cross and When Deception Fails: The Theory of Outs. Each examination dives into extensive case studies to establish not only bedrock understandings of essential espionage principals, but also creates guidance for their practical application on both individual and governmental scales.
Deception is a basic tactic used by allies and enemies alike, but when both protagonist and antagonist ply the same trade, it is the master of the double-cross who comes out the victor. Turnabout examines exactly how to turn the tables on an opponent and use their own deception against them. Through 38 case studies this monograph dissects the double-cross to reveal the psychological battle of wits at its core.
No matter how well crafted, however, there is always a chance that a deception will fail. But failure is not the end of a deception, and even failed deception operations can yield results. When Deception Fails pores over 60 case studies to determine why a deception will fail, steps to prevent a failed operation, and how to turn that failure into a success. Through his analysis of the Theory of Outs, Whaley identifies the cunning required to recapture the initiative rather than allowing an error to turn an operation into a total loss.
Like I say - I just hope it is not too academic. Whenever I see the word monograph - 9 times out of 10 it is gonna' be a dry read!
