Romantic fiction, but based on reality. this book has been totally suppressed by various editors. The author had to self-publish in the end. She seems to have passed away recently but wrote quite a bit about the OSS in WWII. The stories were of such import that she wrote them legally blindly with voice software! WWII must have been a hell of a case of PTSD! From what I gather, she was in the OSS during the war and later went on to be a celebrated psychologist, being one of, if not the first, woman to graduate with a PhD from Virginia.
Worth a dig and a read.
