The basic mind-control premise and related stuff is of course deeply silly, but if you can look past this is an entertaining book. 
 

Silly, but not terrible.

I'd love to be able to shop where this author does - imagine being able to buy a brand new 25,000 ton pleasure boat with 200 first-class and 320 second-class cabins, for the sum of ... 2 million (1950-ish) dollars.. (Doctor Evil laugh definitely incoming, but this obviously was an unintentional joke - the author really is that clueless...)
