The Red Saint by Warwick Deeping

Night came while Marpasse and Isoult were building a fire under the lee of a grass bank in a meadow outside Guildford, for Marpasse, shrewd woman, had no sooner heard the din that the King's men were making in the town, than she had chosen to pass the night in the open rather than within the walls.
