Caroline snapped her head round so sharply that her wig—an unfamiliar article—went askew on her head. She clapped a hand on it to hold it in place while she looked up and across the square, tracing the gaze of the man on the black horse. Immediately she saw a man standing on the roof of the alms-house, perched on the ridge, and keeping one hand on a chimney for balance. This fellow scrambled round as quickly as he could without falling, turning his back on Monmouth Street to gaze north across Broad St. Giles’s and east to one of the street-ends that spilled into that side of it.
