Nazi in the Irish speaking regions.
Kevin Magee uncovers the work of Nazi party member and Irish scholar Dr Ludwig Mühlhausen. Mühlhausen spent six weeks in the Gaeltacht hamlet of Teileann in South Donegal in 1937, collecting folklore and improving his Ulster Irish, but that was not the only work he carried out while he was there. As Kevin reveals, in reality he was working as a Nazi spy, gathering information and passing it on to the Third Reich.

Kevin first visited Teileann 40 years ago to learn Irish. He has continued to visit there ever since and over the years he heard stories of Mühlhausen's visit to the area. Kevin decided to get the bottom of this mysterious tale once and for all. His investigation takes him from Donegal to Dublin and on to Berlin where he uncovers the real work Mühlhausen was involved in the Nazi Party.
