Behind A Mask - A Woman's Power by Louisa May Alcott / A.M. Barnard. Behind a Mask, or A Woman's Power is a novella written by American author Louisa May Alcott. The novella was originally published in 1866 under the pseudonym of A. M. Barnard in The Flag of Our Union. Set in the Coventry Mansion during the Victorian era, the wealthy family hires a young woman named Jean Muir to be the governess of sixteen-year-old Bella. When she first meets the Coventry family, Jean succeeds in charming Bella, Ned and Mrs. Coventry by having a fainting spell. However, Gerald and Lucia, son of the estate and cousin to the Coventry family, remain suspicious. They are skeptical with good reason, for when Jean retires to her own bedroom, she removes her costume (a wig and some fake teeth) to reveal that she is actually an actress of at least thirty years of age.
