A well written account of a lesser known WWII story. Could have taken more care with the use of portuguese expressions. Calling someone "Dono" was never a proper greeting and sounds really creepy. The correct form is Dom if he belongs to an aristocratic family and Senhor if not. Senhorinha is only used in Brazil, in Portugal it is simply Senhorita.
Despite these annoying issues that would only concern Portuguese readers, I did enjoy the book and the plot. The characters are interesting and mostly likable. I especially enjoyed the chapters in Casablanca.
