Indecent by Carole Mortimer

Impoverished Miss Emma Harris can hardly believe her good fortune when Adam Stirling, the handsome and imposing Duke of Hawkwood, asks her father for her hand in marriage.

However, she feels thoroughly humiliated when she attends a masked ball that very same evening and sees
Hawkwood in a compromising position with a married woman. A very compromising position, in fact it is positively INDECENT.
Angry and upset, Emma confronts Hawkwood with what she saw, accusing him of only wanting to marry her as a shield to his affairs with other women. Accusations the duke denies.

Half in love with the arrogant Hawkwood, Emma is devastated when she learns the real reason he asked her to marry him.
But if Emma thinks Adam is the type of gentleman to meekly accept her rejection, she is about to learn exactly how INDECENT he can be when he wants something as deeply as he now wants Emma.
