Marco's Comments:
Well... hardly a book worth its price. The ideas Mr. Thompson puts forward are quite old (Soothsayer), where by analyzing frequency of words, one can guess the most likely word to be chosen. A link is provided to an internet resource where these words can be found (in English language only). Unfortunately, the work provided by Mr. Thompson is a big step backward, as the most frequent words are also indicative of the method he's using. It's hardly worth ask a stranger to select any word from a book, to then learn its first letter (T) and say the word is "Then"...
A couple of interesting ideas are however to be found in this book, otherwise it's not worth wasting time on.
