Curiosity lent strength to the legs of the two Rovers, and they covered the distance to the Brice cottage in an incredibly short space of time. As they came into view they beheld Grace watching for them. She held up her hand for caution. She was standing in among some bushes by the roadside.

"She is watching them."
