Invitation to Valhalla is popular among American troops.

Here Mike and Alex check out a captured World War II German Enigma code machine. The Enigma code plays a role in Invitation to Valhalla and Blood of the Reich.

Looming ahead on the Ohio River is the bridge from Indiana to Kentucky that Erika Lehmann plunge from in Invitation to Valhalla. The photo was taken by the author from the deck of LST 325, the last fully operational WW II LST in the world.

The apartment has been abandoned for many years. This is the bathtub Erika was in when Axel Ryker broke in on her.

I just finished the book and found it fascinating since I am from Indiana. Thank you for bringing this part of our history to light. My wife is originally from the Evansville area and we now have many more sights to go visit when we head down there. In fact, her Grandmother, Katie Hirsch, grew up just a few blocks from the cafe where Erika stayed and her Great Aunt is the photographer of the pictures posted here (Cookie Barrow). Thanks again for the great read.

I have read the book twice and have used it in teaching WWII to 6th graders at my daughters school. just donated a copy to the school as many kids wanted to borrow my book. my daughter is also a fan. This summer when we visited my Mom (Cookie’s sister Katie) we went to the old neighborhood and saw how close all of this happened! My Mom was just a few blocks away! As a teaching tool is was great to show how even back then our country was being infilterated. Can’t wait for the second book! Many new fans are being developed in Columbus GA.

Getting ready to re-read “Blood of the Reich”. There is so much packed into the book, it requires a second, slower read.

Am just ready to finish the last few pages of “Blood of the Reich” for my bookclub discussion tomorrow and savoring this moment. Absolutely love it. I live near Evansville, Ind., and have family in Cincinnati, OH. Can’t wait to share the book with them. This will be one book I will re-read.

I read Invitation to Valhalla, Proper Suda, then Blood of the Reich, one after the other. I loved them all. I didn’t want to get to the end of the books because they were so exciting. I seriously would love to see them made into movies. That would be great! Like the others mentioned, you want to read them again to catch things you didn’t the first time, because you were in such a hurry to see what happened next. It is so cool to read a great story about events that occurred in your own town too. I hope you have another book in the works. Maybe you could write a book about Haiti.
Your Fan, Jackie

Mike,
Two of your books were a gift to me from a friend and I greatly appreciated you hand delivering them to London last month! Sorry you were at Bletchley Park the day I picked them up. I’ve spent most of the weekend reading them. Started Invitation to Valhalla on Friday night and just finished Blood of the Reich. Well written; I couldn’t put them down. I am dying to know what happened to Erika! What a fascinating woman!

Correction: certainly FBI Agent Charles Pulaski would have known that robber and gunman Lester Gillis, sometimes known as “Babyface Nelson, if not to his face, found the Thompson machine pistol to be bulky and uncontrollable, and avoided its use, as at the Little Bohemia Lodge in Wisconsin, as described in Invitation to Valhalla. Gillis prefered the “rattler” a Colts Government Model pistol modified to fully-automatic fire, and in the .38 calibre super cartridge chambering rather than the more usual .45 of the army service weapon.

Heinrich: Great info. But Nelson also used a Thompson on many occasions. He used one to kill two FBI agents in 1934.
