Whilst lost in the Derbyshire Peak District, and purely by chance, John Staple comes upon a toll-gate at the dead of night. Strangely there is only a young boy there to operate it. His curiosity pricked, John decides to stay and find out what is going on. Here begins one of Heyer's adventure stories, with mystery, villains, and plenty of derring-do. It is a romance of course, and Nell Stornaway, coping bravely in the face of adversity and very trying house-guests, is attractive as all of Heyer's heroines are. As ever, the charming and funny minor characters are half of the joy of the story. A pleasure to read, and good enough to come back to again and again.
