John Harris 
Sea Shall Not Have Them [EPUB ebook] 

This is John Harris’ classic war novel of espionage in the most extreme of situations. An essential flight from France leaves the crew of RAF Hudson missing, and somewhere in the North Sea four men cling to a dinghy, praying for rescue before exposure kills them or the enemy finds them. One man is critically injured; another (a rocket expert) is carrying a briefcase stuffed with vital secrets. As time begins to run out each man yearns to evade capture. This story charts the daring and courage of these men, their rescuers and a breathtaking mission with the most awesome of consequences.
