Most Secret [EPUB ebook] 

In their trusty fishing boat Genevieve, armed with a flame thrower and limited ammunition, a small group of officers and men take a stand against the might of the German army after the fall of France in World War II. This is classic Shute: at once a thrilling adventure that will keep you on the edge of your seat, and a heartbreaking tale of the ravages of war.
