The Perfect Sin by Kat Martin

Randall Clayton "Rand", seventh Duke of Beldon is confronted with an unusual problem. He is falling in love with Cait Harmon, but he suspects her father in the death of his cousin. Rand is unable to hide his passion and need for Cait. This story runs the gamut of sexy scenes to island dangers. An enjoyable read! Several characters from her "Wicked Promise" book, that I will have to go back and renew my acquaintance of them (grin). This is in addition to lots of questions answered concerning plot, characters, locale, etc. about the book.
