Lady Cecilia of Danby Hall feels adrift. She couldn't be less interested in helping to plan the church's upcoming bazaar. Instead, what excites her most is the Woman's Suffrage Union meeting she has just attended.

Inspired by the famous and charismatic leader of the group, Mrs. Amelia Price, Cecilia is eager to join the Union--if she can hide it from her parents, that is. But when Mrs. Price is found dead at the foot of the stairs of her home, her Votes for Women sash torn away, Cecilia knows she must attend to a more urgent matter: finding the killer. With the help of her lady's maid Jane and intelligent cat Jack, she hopes to play her part in earning women's equality by stopping the Union's dangerous foe.
