The Dark Frontier

The Dark Frontier (1936) is Eric Ambler's first novel, about whose genesis he writes: "[…] Became press agent for film star, but soon after joined big London advertising agency as copywriter and "ideas man". During next few years wrote incessantly on variety of subjects ranging from baby food to non-ferrous alloys. Have travelled in most countries of Europe, been stranded in Marseilles and nearly drowned in the Bay of Naples. Decided, on a rainy day in Paris, to write a thriller. Result was The Dark Frontier."Based on the development in weaponry of the year 1936, The Dark Frontier was one of the first novels to predict the invention of a nuclear bomb and its consequences. Ambler evidently had no knowledge of what producing an atomic bomb may involve (even professional physicists at the time had only a vague idea). The book makes no mention of uranium or any other radioactive material, and makes instead the assumption that setting off an atomic bomb would involve a considerable electric charge. Still, Ambler could be credited with having become aware, before many others, of this coming weapon which was to have such a profound effect on the entire world, and his depiction of scientists in a secret hideout building such a bomb could be considered a preview of the Manhattan Project - and he correctly surmised that refugees from Nazi Germany might get involved in such a project.
