In the coldest flint, there is fire... Casper Brook, the eighth Duke of Rothwell, has forever spurned frivolous pleasures, his restless emotions remaining buried beneath duty and command. Yet when a titian-haired minx perches upon his ducal desk and claims to know the whereabouts of his one burning obsession, a game of wits and passion erupts...

Fire ignites from a spark... Miss Evelyn Pearce possesses naught but a frail young sister and an ebony-black cat. Left destitute by her baronet father's spendthrift ways, fate and talent hand her the opportunity to seek escape from the dangerous alleys of London town. The cold Duke of Diamonds holds the key, and all Evelyn must do is resist his not-so-cold kiss...

A dance of flaming desire... A passion forged on secrets can never be satisfied, but as guises fall and plots unravel, will the duke's controlled façade shatter to reveal his searching heart within?
