Lex Pellier is passionate about only two things in life: her
Cluny Museum in Paris. She relishes the idea of discovering a medieval treasure. Unfortunately, her trip to a convent near Lyon, to examine a storehouse of items dating back to the thirteenth century, seems to be turning up little. But then, tucked inside a book, Alex discovers a centuries-old poem. In another book, a series of sketches. To Alex, these items suggest that there may be a seventh, as yet undiscovered tapestry in the world-renowned The Lady and the Unicorn series.
