"I must be going now," she said rising from her seat. "I will bring the bonnet and shawl to-morrow night about nine o'clock, and throw it over the gate; and you must get away from here soon after five on Sunday morning, and walk to the first milestone on the London road. We shall be along there about six, and then we can hide you out of sight. But mind, if a policeman should be near you, just walk on, and don't even look at me or the caravans till I speak first."
