The Unwanted Heiress (The Archer Family Series) (Volume 2)

When Nathaniel, Duke of Peckham, meets Charlotte, he's suspicious of her indifference. Too many women have sought--and failed--to catch him. Happily, Charlotte is more interested in dead pharaohs than English dukes and laughs at both him and his suspicions. Her resistance crumbles, however, when a debutante seeking to entrap Nathaniel gets murdered. All too soon, his reputation as a misogynist makes him a suspect, and Charlotte impulsively comes to his aid. Unfortunately, both are unaware that a highwayman interested in rich heiresses is following Charlotte, and that another debutante lies dead in Nathaniel's carriage. 

The Unwanted Heiress is a sweet, traditional Regency in the tradition of Georgette Heyer, full of fun, witty characters who refuse to fit the traditional roles set out for them. Add in a touch of mystery and you have a book that will keep you entertained and guessing.
