It is May 1944. Something huge is coming.

After a well-earned rest following their collective escape from the Reich, Monika Ritter, her husband, Michael, her cousin, Sarah, and her fiancé, Oliver, resume their respective duties. Michael returns to Switzerland to fly for the OSS once more.

Sarah goes to Berlin alone to continue the flow of information from the most critical OSS asset in Nazi Germany. Oliver, a former Wehrmacht soldier, is sent undercover into a British POW camp in Wales with a mission to integrate himself into a group of potential escapees before embarking on a secret mission at the heart of the D-Day landings.

Monika is dispatched to Austria. Her task there will be to oversee a group of native infiltrators sent back to eliminate a brilliant German general in his summer home. But when the mission goes wrong, Monika will once more have to take the lead and, through cunning and ingenuity, see out an assignment that could change the face of the war.

THE Infiltrator is the sixth novel in a new series by the #1 Amazon bestselling author of WHITE ROSE, BLACK FOREST, and THE MAUREEN RITTER SERIES. Download it and discover Eoin Dempsey’s books today.

This book had me from the start. I wasn’t familiar with the characters, but they came to life immediately and it was very easy to slip into their world.
Amazing narration by Issy Arnett. How she managed to portray each individual character with a distinct, yet totally believable voice is simply incredible! Da iawn.

The title, and cover picture, drew me to click 'preview', a little shallow perhaps, but so many titles to choose from! Hearing an English female voice immediately took me to think of old black and white war films I grew up with, yet here is a story line where the female character takes the lead and the story line is plausible, that's different. The author's location descriptions and writing takes you to imagining the scene quickly, together with steady narration enabled an engaging plot and storyline to follow. A number of characters hold your attention, and I did not get lost in 'character confusion', despite there being a number to keep track of, a shout out to Issy Arnott for that.
I will continue to the next book in the Monika Ritter series, I like that a gender balance has been brought which I feel will bring a further depth to future storylines.

This story had me hooked from start to finish! I absolutely loved the story arc and the insight we were given through the different character POVs, alongside Monika Ritta’s journey. It was exciting, emotional, and beautifully paced throughout.

The narrator was absolutely fantastic. With such a large cast of characters and accents, every voice felt clear, distinct, and thoughtfully performed with real care and sensitivity. I thoroughly enjoyed the entire audiobook and would highly recommend it!

Hooked from start to finish!!

I really enjoyed this book and Arnett's narration was spot on! The writing and excellent narration really brought these characters to life and there were times where I was anxiously waiting to find out what would happen. I'm off to check out the others in the series now!

This is a richly developed story that draws the listener into the complex world of WWII espionage but the delicate character development is what makes it so compelling. The incredible narration that includes both genders and multiple accents is superb, I will follow both the narrator and the author for more.

Beautifully written & wonderfully read
