Query: Brilliant insights from a master

Dunn takes the cake from the grave! While the Crook Society scrambles to promote the old faker Dr. Cook, and Bryce tries to sue Washburn for his book about the McKinley fraud we have Dunn's magnificent work back in print.Skip the modern intro (how ridiculous!) as Dunn's razor sharp writing needs nothing added. Was Cook a fake? Of course! And far worse than that - he is seen here as a sociopath, a failure, a miserable little worm who couldn't lead a horse to water.It is wonderful that publishers are putting books back in print such as this one, or the Denali (Deception, etc.) triple reprint. In addition to this group we now have Washburn's brilliant images that say more in a few photos than Bryce did in 100 pages.A fascinating study of an expedition gone to [junk], by the man who taught everyone else how to "tell it like it is".
