If anyone knows where in Vienna the Abwehrstellen was, I'd appreciate hearing about it. Research for a novel. Also, my research has turned up that the SD was on Theresianumgasse, 16-18, the former residence of Nathaniel Rothschild; if anyone knows differently, or thinks another agency was in that building, please advise accordingly. I don't want to get it wrong. Thanks in advance. Great forum, happy to hear it will continue on with new leadership.
