Tempt Me with Diamonds by Jane Feather

There is just so much sexual tension between Rupert and Diana, “well,” he murmured finally, “I don’t know why you unman me so, my sweet, but I cannot help myself. I didn’t come in here intending that to happen, I was ready for battle.” He moved his hand from his eyes dropping it heavily onto her belly." When he's with his lady, Rupert hates being disturbed, “no, we most definitely are not at home,” Rupert declared. “Send Mr. Marsden on his way, and for the rest of the day, we will not be at home to anyone. Is that clear, Barlow?” I really liked this book, I loved Rupert.
