The Infiltrator (Monika Ritter #6)

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.
