The text provides excerpts from W.D. Gann's novel The Tunnel Thru the Air, which follows the story of Robert Gordon, a young man who uses his knowledge of Bible prophecy and cycle theory to make a fortune in the stock and commodity markets. The novel is written in a style that blends romance, adventure, and spiritual themes, and it features several key elements like Robert's love for Marie Stanton, his ambitious inventions, and his ultimate goal of helping his country. The book is a testament to Gann's unique perspective, where Biblical interpretations play a key role in shaping the narrative, and events unfold according to a predetermined pattern, which is revealed through his intricate calculations and predictions.
