La mystérieuse histoire de l'oeillet rose, tome 1 de Lauren Willig
The Scarlet Pimpernel, The Purple Gentian, The Pink Carnation... The very music of their names invoked a forgotten era, an era of men in knee breeches and frock coats who dueled with witty barbs shaper than the points of their swords. An era when men could be heroes.
The Scarlet Pimpernel, rescuing countless men from the guillotine; The Purple Gentian, driving the French Ministry of Police mad with his escapades, and foiling at least two attemps to assassinate King George III; and The Pink Carnation... I don't think there was a single newpaper in London between 1803 and 1814 didn't carry at least one mention of The Pink Carnation, the most elusive spy of them all.
