The Deception of the Emerald Ring (Electronic book text)

Eloise Kelly has gotten into quite a bit of trouble since she started spying on the Pink Carnation and the Black Tulip-two of the deadliest spies to saunter the streets of nineteenth-century England and France.
Not only has she unearthed secrets that will rearrange history, she's dallied with Colin Selwick and sought out a romantic adventure all her own. Little does she know that she's about to uncover another fierce heroine running headlong into history.
