The Exploits & Adventures of Miss Alethea Darcy by Elizabeth Aston

The Exploits & Adventures of Miss Alethea Darcy takes readers back into the imagined family of Elizabeth Bennet and Mr. Darcy. Their musical daughter Alethea makes a disastrous marriage to a man whose charming manners conceal an unpleasant nature. Flinging caution to the winds, she flees her marital home, masquerading as a gentleman, and accompanied only by her redoubtable maid, Figgins, she sets off for Venice to take refuge with her sister Camilla. But events -- always dramatic and sometimes dangerous -- conspire to thwart her plans. Before she can meet up with Camilla, chance and her love of music lead her into the world of Italian opera, while her encounter with the aloof and difficult Titus Manningtree, in Italy to pursue a lost Titian painting, is to change her life -- although fate has several more tricks to play before she can find happiness.
