One side of Lady Ingram’s mouth curved down, the side where her beauty mark had been. A woman on the run couldn’t afford such a distinguishing characteristic; now there was only a slight dent. The dent on Constantina Greville, at the same spot, must have been to disguise the fact that she had never had a beauty mark.
Thank goodness. I was afraid they thought twins would have the same birthmark. Yay for gene expression differences during development!
