Mr. Lloyd's credibility plummeted when I began to read the first pages of his introduction to this lackluster book. The entire introduction appears to be a condensed summary of the first three chapters of Colonel Michael Dewar's excellent book titled "The Art of Deception in Warfare." In fact, Mr. Lloyd seems to have relied more than heavily on Colonel Dewar's book. Even the title is nearly the same.
Even more maddening is that Mr. Lloyd has included a fair amount of material that seems to confuse self delusion and incompetence with strategic and tactical deception. In Chapter 1 he devotes several pages to the American revolution and the Zulu and Boer wars in Africa. Nothing in that chapter has anything to do with the principles and techniques of deception in warfare.
A better investment is to hunt down a used copy of Colonel Dewar's book. It is a far, far better resource if you are interested in the principles, means, and techniques of strategic and tactical military deception.
