The prince of midnight

In the late 18th century, intent on avenging her family's death at the hands of a cult leader, Lady Leigh Strachan dresses as a boy and seeks out the reclusive S.T. Maitland, nobleman and highwayman, who was once known as the Prince of Midnight. Hiding in a crumbling castle in France, with a tame wolf as his pet, the hero is deaf in one ear, suffers from vertigo, and seems revoltingly sentimental to the stoic Leigh. But he joins her quest and together they begin to emerge from their individual suffering.
