John Braddock

If you change the name to "A Scientists Guide" you have the first chapter of every science class textbook. The only difference is you replace report with action.
It's only 43 pages long and it repeats itself a lot.

The brevity of this guide to thinking is a guide! Spies can't be slow thinkers, as the case study shows. This book has not been fluffed out to make it longer - refreshing and good. Interesting if DADA is unknown to you.

Good insights

Good outline of the intelligence gathering and analysis process. Provides a basic framework for data analysis, decision-making and taking action.

Not much to it but it was a fun read. Braddock discusses the thought process and how a spy analyses situations using a confrontation with a druggy on a train as a frame of reference (which happened to him on the to a covert meeting). This is a Kindle single so it can be read easily in one sitting and in less than an hour.
