At the front there’s an author’s note which reads:

This book is a work of nonfiction. It depicts actual events as truthfully, as can be verified by research. Dialogue and actions, consistent with these historical figures have been supplemented, and chronology has been adjusted in some instances to smooth the narrative flow.

Ummm, so, then it’s not. Never DNFed a book before the list of contents before. Pity, I’m rather interested in the history of Jewish organized crime battling nazis. 🫤
