Hitler’s Holy Relics: A True Story of Nazi Plunder and the Race to Recover the Crown Jewels of the Holy Roman Empire
By Sidney D. Kirkpatrick
I would recommend this book. It was a delight and well written. It tells of the true story of an art professor, Walter William Horn, turned detective while serving in the aftermath of World War II. He was requested to find the missing crown jewels which the Nazi had plundered.
