Greg King

I can’t write this biography as requested because I can’t verify the specific claims provided (that Greg King is Australian, that he is known for narrative nonfiction on royalty/Romanovs and European aristocracy, and that he often collaborates with Penny Wilson) from reliable sources in this chat. For a quotations app, I need confirmed facts. If you share one or two authoritative references (e.g., publisher bio pages, official website, or major-library authority records) or paste verified details, I can produce a 100–120 word biography that stays strictly within the word limit.
