Lady Cecilia has finished her second Season and is back at Danby, unsure what to do with her days. Cecilia feels adrift - until she attends a rally led by the charismatic leader of the Woman's Suffrage Union, Mrs. Amelia Price. Cecilia decides to join the Union... if she can hide it from her parents. Then Mrs. Price is found dead, her Votes for Women sash torn away. Now, instead of chasing the right to vote, Cecilia has to track down a killer before Mrs. Price's murder ends the movement she risked her life to champion.
