The Courtesan's Letters

Miss Abigail Todd, the very proper headmistress of an academy for young ladies in Boston, arrives in England to settle her grandmother's estate, only to discover that her ancestor was la grande Clarisse, the most notorious courtesan of her day. And, to her even greater horror, she herself is the perfect image of her grandmother. Clarisse has left a series of letters detailing commissions Abby must carry out in order to obtain her inheritance (an amount far greater than anticipated).
In order to do this, she must accept the assistance of Jared, Earl of Langley, grandson of the man who was Clarisse's devoted lover for forty years. Has Clarisse created these letters because of love, nostalgia, mischief, vengeance .
