Known as The Maid of Mayfair for her unassailable virtue, unwavering resolve, and quiet dignity, suffragette leader, Caledonia — Callie — Rivers is the perfect counter for detractors' portrayal of the women a rabble rousers, lunatics, even whores. But a high-ranking enemy within the government will stop at nothing to ensure that the Parliamentary bill to grant the vote to females dies in the Commons — including ruining the reputation of the Movement's chief spokeswoman.
After a streak of disastrous luck at the gaming tables threatens to land him at the bottom of the Thames, photographer Hadrian St. Claire reluctantly agrees to seduce the beautiful suffragist leader and then use his camera to capture her fall from grace. Posing as the photographer commissioned to make her portrait for the upcoming march on Parliament, Hadrian infiltrates Callie's inner circle. But lovely, soft-spoken Callie hardly fits his mental image of a dowdy, man-hating spinster. And as the passion between them flares from spark to full-on flame, Hadrian is the one in danger of being vanquished.
