The Masque of the Black Tulip by Lauren Willig Eloise is a Harvard graduate student, writing her dissertation on English spies in France after the Revolution. She’s in England, worming her way into old family archives to find the truth behind spies who, unlike the Scarlet Pimpernel, were never unmasked during their lifetime. Her modern-day dilemmas are the frame for the story of the spies she’s researching. In this second book of the series, our spies are Lady Henrietta Selwick and Lord Miles Dorrington. They are under great suspicion from France, as they are the little sister and best friend of Lord Richard Selwick, formerly the Purple Gentian. Either one of them could be or could lead the French to the Pink Carnation, the subject of the first book. In fact, the Pink Carnation is trying to get word to them that France has unleashed its deadliest assassin, the Black Tulip, on England. Both Hen and Miles are eager to help the Pink Carnation discover the identity of the Black Tulip. Miles is struggling with the realization that Henrietta is prettier than ever – and strictly off limits. It is equal parts intrigue and romance, with each cropping up at inconvenient moments for the other. The author, herself a Harvard graduate student, pays attention to historical accuracy, with a note at the back to explain where and why she changed things. This is delicious fun.
