Under The Pope's Windows: A K9 Thriller Where Stolen History Sparks a Deadly Global Pursuit (Rex Dalton K9 Thrillers Book 8) Kindle Edition

4.6 out of 5 stars 1,136 ratings

They stole it. He's going to take it back—by force.

In 1943, as Nazi troops stormed Rome’s Jewish Ghetto, they looted two ancient libraries filled with irreplaceable manuscripts. The theft happened in plain sight—under the Pope’s windows.

Now, decades later, Rex Dalton, his wife Catia and their loyal military dog Digger are on a mission to recover the stolen manuscripts and return them to their rightful owners.

But their quest quickly turns deadly. Modern-day Nazi diehards, powerful anti-Semitic forces and a secretive elite determined to bury the past will stop at nothing to keep the truth hidden. With enemies closing in and history hanging in the balance, Rex and Digger must fight a ruthless conspiracy that spans generations.

Under the Pope's Windows is the heart-pounding eighth installment in JC Ryan's electrifying Rex Dalton K9 Thrillers series.

What readers are saying about the Rex Dalton Series:

Sheila LS - Top Contributor. Can't Read This Series Fast Enough!! I had no idea these books were so good when I first started or I would not have already downloaded other Kindle Unlimited books... I haven't read any series as exciting as Ty Patterson's Warrior series until now.

You really need to start reading this series from the beginning because what happened to Rex in this first book is what made him the way he is. He is a very determined person and does not stop at anything to take down the bad guys--especially if they are terrorist or if it is a group that is funding terrorist. Even though this is his main mindset, he still wants to protect the innocent that inadvertently get in the way...

Texas - This author belongs on the same shelf as Ludlum and Follette and those other guys! My first read by this author and I couldn't put the book down! Mesmerized by the writing style, the vivid descriptions and the storylines, I read without stopping. Fast paced, action packed and interesting on several facets.

Margaret Bentley - I love reading about Rex Dalton's exploits, but my favorite character has to be Digger, his military-trained super-intelligent dog.

Greg D - Rex Dalton was the deadliest agent the government had at their disposal- a one-man unstoppable force in the war on terrorism in the Middle East. With his famous ability to pick up new languages with ease, he figures he can blend into almost any culture and root out evil. What could go wrong? Well, it turns out, plenty.

E. I. HOOD - I was not a fan of the first Rex Dalton book but plunged ahead with the second hoping JC Ryan would not disappoint. I loved it. Now here I am after reading the third book in this series. I had a hard time putting it down and found myself wondering about it when I was not reading.

40 year pioneer - Each book in this series gets even better. This has a fascinating, even though hard to fathom, plot, worked out in intricate detail. Rex Dalton is a mirror of all of us - overcoming seemingly overwhelming odds to achieve great things.

Kindle Customer - From a master storyteller comes another thrilling ride by Rex Dalton. From the sands of Afghanistan to the culture of India the story moves at a breathless pace. Thoroughly enjoyable and highly recommended.

Kindle Customer - Rex Dalton rocks! Another great read from JC Ryan. I've read all of his books and am never disappointed! All I can say is....MORE!

    This story line mixes WWII history with modern day efforts to track down 2 treasured & valuable Ancient Jewish libraries that were stolen & remained hidden for 70+ years. Rex's Italian wife, Catia, is looking to finish her doctoral degree & wants to discover whether those ancient books were destroyed, lost, or stolen. But as she, Rex, Digger & friends delve into the trail, they are met with evidence that there are many International players who wants the answer to remain a mystery. JC Ryan weaves his storylines & characters so well that you get invested in the series. Intriguing, inventive writing of terrific (super) hero/es who manage to save the day, no matter what or who needs it. Bring on the next one!

    First, let me urge you to so some extensive reseach into the history of the Vatican's involvement with the Nazis both eforee, during, and after WWII as well as records finally released in the last two decades regarding Pope Luis XII and the corruption in which he was complicit... Your blood will run cold, Then research deeper into the wealth looted by the Nazis from individuals and countries they conquered/looted, that disappeared and the VERY small percentage til that was ever recovered...it boggles the mind. And finally, discover how many many high profile Nazis were never captured/ prosecuted but instead " escaped" with new identities to live out their lives to a ripe old age in comfort. If you are not already awash in tears and shock, imagine that wealth at work in the hands of zealots who still to this day despise the Jews and await the chance to resurrect the specter of the Third Reich anew in a Fourth Reich... And with all that information confirmed by historical documentation, sleep tight....if you can do so..... A flawless and deeply frightening look at a period in history that best not be forgotten lest it be repeated!

    This was an intense, complex, and heartbreaking story of how much WWII impacted the world, mostly the horrific and inhumane actions of the German Nazi, even almost 75 years later. It's certainly not a story that you'll want to miss.
    I would definitely recommend this book, series, and outstanding author.

    Just another brilliant story with Rex, Catia, Digger and the team. This time they are tasked with finding the Jewish libraries that were stolen by the Nazis from under the Pope's window. This is all because of Catia's thesis for a doctorate about the libraries. CRC are given permission to be involved as well as Missed which gives plenty of action.
    Again there is plenty of background surrounding the Nazi's part in the thefts as well as the people who want them to remain hidden so that certain secrets are not disclosed.
    To date this has been an extremely good series to read and given me hours of pleasure. I see there is another book now and must find out it's availability.
