"The Last
Lieutenant" by John J. Gobbel 
A German spy takes
the place of a Navy cryptographer and causes all kinds of problems
during the fall of the Philippine Islands on the outset of America's
entry into WWII. This is a well thought out book with lots of
thrills and devious turns, and interesting characters. It also
describes accurately many historical events and people that give
the reader the additional bonus of learning something.
