[The Lothian Run is a] romantic adventure story with an element of mystery and some meaty historical background. Few writers today are more skilled in this genre than is Mollie Hunter…. [The] story moves suspensefully through a series of intricate and dangerous adventures and counterploys. Gilmour is a glamorous Pimpernel, Sandy a diamond in the rough, and the villains are absolutely heinous…. [A] rousing tale. (pp. 69-70)
