Marie Louise Rebecca Haverford is the pampered only child of Sir Julian and Lady Becca, with whom she has a loving, fun-filled relationship. Although she presents the expected frivolous demeanor to society, she is, in fact, quite intelligent as her father learns when she interferes with his work at Whitehall.
Soon after their arrival in London for her second Season, Marie meets John, Viscount Beaufort, a Whitehall associate of Sir Julian. Lady Becca warns her that Beaufort is immune to young misses, but Marie vows to change all that.
Marie's shifts between maturity and immaturity confuse Beaufort, yet he admires her grasp on life. He resists Marie's blandishments, partially because he distrusts frivolous females, but also because theft of funds meant for the military in Spain occupies his attention.
Marie is accustomed to getting what she wants, so why does Beaufort not succumb to her blandishments? After all, she is beautiful and wealthy. She never offends by exhibiting any intelligence. As expected by society, she flirts deliciously, pouts adorably, and dazzles every male within view. Every male, that is, except the one she desires. Must she place her life in danger to win Beaufort's attention? She will do even that to win her heart's desire.
