THE HERO (Ruthless Regency Dukes 5) is the fifth book in International #1 Bestselling Author, Carole Mortimer’s, Regency Romance series.

Six Dukes, bound together by their friendship and loyalty. When one of them is murdered, the five friends remaining are each given the task of investigating one of the five officers suspected of being responsible for the killing.

Gideon Harrington, the Duke of Oxford, is the last of the five Ruthless Dukes tasked with identifying the person responsible for killing their friend, the Duke of Plymouth. Something, in view of the eccentricity of the gentleman Gideon is to investigate, he admits to having delayed for as long as possible, in the hope one of the other dukes will succeed in identifying the culprit.

Unfortunately, that does not prove to be the case.
Learning that his quarry, Henry Church, the Earl of Dunhill, is to attend a house party at the end of the month, Gideon secures an invitation for himself to attend that same party.
He is not in the least prepared for the hoyden that is Henrietta Church, Dunhill’s daughter. A young lady who insists upon being called Harry and proves to be as eccentric as her father.

Harry has never met anyone quite as disdainful and toplofty as Gideon Harrington, the Duke of Oxford.

A gentleman who makes no effort to hide his disapproval of her.
A gentleman she, in turn, takes great delight in tormenting because of his haughtiness.
But Harry soon learns, to her complete and blushing surprise, that Oxford is hiding a very passionate and possessive nature beneath that haughty exterior. A discovery she finds irresistible.
Except she has no idea of the real reason Oxford is attending the house party.
