Doctor Victor Hunt and Professor Danchecker travel from Britain to the United States, to head a project that will lead them into an adventure much different from the one they know. They are bringing with them a Trimagniscope, a remarkable machine that can scan and read the text on any page of a closed book. When they reach Texas, their final destination, they will learn of a discovery that will keep them and many other scientists busy for several decades. A discovery that could have ramifications on the history of mankind.
