When Sir Walter Pendennis asks her help to stop a treasonous uprising, how can Lady Appleton refuse? Pretending to be someone else, she infiltrates the rebel camp and puts her own life at risk, but it isn't always easy to tell the villains from the heroes and the two feisty countesses leading the Rebellion of 1569 are forces to be reckoned with. Historical Mystery by Kathy Lynn Emerson. 6th in the Face Down series originally published by St. Martin's.
