You can't be too suspicious when security is at stake. When everybody who is after a key military job wears a toupee, it is obviously a bald case of espionage.
This is a relatively weak book with a thin and incredible plot, unrealistic characters and shallow premise. In my opinion, it is not one Vandenburg more interesting pieces of short fiction. Given that it was reasonably short though, it was not too onerous and fills in one of the gaps for me in his writings.
