Frontière des tenebres

Blurb

The Dark Frontier 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 of weaponry in 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. 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.
