"Churchill's Greatest Secret" is a fascinating account of Winston Churchill's hidden history of creating atomic bombs during World War II. Author E. Keith Binnersley shares a thoroughly researched exploration of how Churchill was able to gain access to enough fissionable uranium to make several atomic bombs before the USA's Manhattan Program began. He dives into the complexities of Churchill's involvement with atomic weapons and how he eventually gained control of the United States' atomic bomb. Although this book explores the history of scientific concepts, it's not necessary to have a scientific background to follow the gist of the story. This book's original inspiration came from the author recent discovery that by November 1943, a chemical company in England, known then as ICI, had manufactured 2965 lbs. of a metal they code named "massive metal". Extensive searches by the author established that "massive metal" was metal enriched with the uranium isotope 235U, the active ingredient in the atomic bomb dropped by the USA on Hiroshima in August 1945.
