With Lee's name it hadn't taken long for Antonin to track down his home. Hermione used to know every single contact and connection her husband had. As time wore on and he became more secretive and power-hungry, she was left more and more out of the loop. She had once been his partner, practically equal in everything they did. A lot had changed. He saw her alternatively as being either something weak and precious he needed to protect or a potential enemy he needed to be suspicious of. If she'd stayed much longer in their home, she wasn't sure what he would eventually do. Probably end up killing her to protect her or some other such rubbish that made no sense.
