From The Grey House:
As she raised the gun to him, Dean lurched forward. He grabbed madly at the gun, hoping to get it out of her hands. By sheer miracle, he pulled it away from her. He took a step back, and they started at each other. She scowled, and Dean lurched forward again. He brought the stock of the gun down on Judith’s head. He was taller than her and it worked. She grunted and fell to the roof. Without hesitating, Dean ran for the rooftop door. In a moment, he was on the third floor. He slipped into an apartment he and Judith had acquired an hour ago.
