Robin stood up and had taken a couple of steps towards the door when something strange happened. She suddenly knew – didn’t guess, or hope, but knew – that Strike had just arrived beside the blind spot at the perimeter fence. The conviction was so strong that it stopped her in her tracks.
I don't know how I feel about this. I'm going to put it down as Robin just being desperate to escape and having absolute conviction and trust that Strike would do what he promised and come for her if she was in trouble.
