Road to the Coast — John Harris

It's South America and a fugitive Englishman is caught in a military revolt against a tyrant. Harry Ash is a wanted man, fleeing the police and revolutionaries. After being bombed, he meets a beautiful woman, Grace Rodrigo, and steals a car to take her with him before realising they have a stow-away who could very well endanger their entire escape plan. John Harris pulls off a triumph of an action-packed narrative full of the kind of tension that will have you on the edge of your seat.
