Lie by moonlight (#4) : Vanza
(Book)

Concordia Glade, a teacher with past secrets and unconventional ideas about educating women, meets Ambrose Wells, a "private inquiry agent" with secrets of his own and an unusual tattoo, as she and her four orphaned pupils flee Aldwick Castle, which they have set on fire to hide their escape. Ambrose escorts the lovely fugitives to safety, protecting them from the criminal mastermind and his aristocratic partner who'd kept them as part of a dastardly plan to use them for profit and pleasure.
