A Our Man in Havana by Vivian Darel Browning

A our man in havana was published in 19 58. Based partly on his experience working for am i six, which is the british intelligence agency. His wife vivian darel browning has a blue name in wicapaedia. A lot of his novels are about religious themes and stuff like that. And then he's got these entertainments where he is just writing fun thrillers. I think this book may have even started from a scream play idea.
