While bathing, Peter Brown was attended by two girls, yet he did not show any particular demeanor; after all, as a prince, he certainly could not show any aversion. A prince has been accustomed to such services since childhood, even Peter Brown didn't mind Philips Williams watching him bathe.
Peter Brown discreetly observed and noticed that after his clothes were removed, Philips Williams also glanced at a spot on his body, and after looking, his face relaxed.
Seeing that spot, Peter Brown understood in his heart—it was a place on Prince Harvey's body with a special mark, which Philips Williams and the others certainly knew about, serving as a means of identification.
Fortunately, when he disguised himself, he had altered various parts of his body to look the same, so even Philips Williams and his people could not discern anything.
