I passed the dark window of the spare room, trying the leaden roof at each step with my foot before I risked resting my weight on it. I passed the dark windows of Laura’s room (“God bless her and keep her tonight!”). I passed the dark window of Sir Percival’s room. Then I waited a moment, knelt down with my hands to support me, and so crept to my position, under the protection of the low wall between the bottom of the lighted window and the verandah roof.
