Imogen Waterstone needed a man, and not just any man: one with an implacable will and nerves of iron. That's why she invited Matthias Marshall, the Earl of Colchester, to her home. For who better than the legendary explorer to help her lure a ruthless enemy to ruin. Yet when Imogen urges Matthias to masquerade as her spellbound suitor -- and let it be known that she possesses a priceless treasure map -- she never anticipates his electrifying response -- or her own. Suddenly, the unconventional lady is in the thrall of true passion... and vulnerable to a malevolent threat that emerges from the labyrinth of London society.
