It's an unexpected answer. Avery was doubtful, "Are you sure?"
"How dare I forget the footsteps of the person who killed Mr. Clifford?" Jamie did not hesitate.
"What I wonder is how she knows where we are? It takes time to locate us in sending someone to hit us with a car. As long as we slowed down a little bit, we might not have a car accident."
Avery was still frightened to think of the scene at that time. The person in the van only had had one purpose, which was to kill them.
After a few seconds of contemplation, Avery speculated, "Has Fiona stalked us all the time? Was she sitting in the van at the time of the accident? After we fell off the cliff, she got out of the van, and you heard her footsteps?"
That would make sense.
If Fiona has stalked them all the way, she must have seen them get in the car at the hospital.
Jamie suddenly said, "I heard that a lady in the Summer family was sick."
