It's 1887, and Annie and Buffalo Bill's Wild West Show are invited to Queen Victoria's Jubilee celebration in London, England. But their long journey across the Atlantic takes a turn for the worst when the queen's royal servant ends up dead and Annie's husband, Frank Butler, falls suspiciously ill. Annie soon discovers that the two events are connected--and may possibly be precursors to an assassination attempt on the queen. In London, it becomes clear there is rampant unrest in the queen's kingdom--the Irish Fenian Brotherhood, as well as embittered English subjects, are teeming in the streets. But amid the chaos, even while she prepares for the show, Annie is determined to find the truth. With the help of a friend and reporter, Emma Wilson, the renowned poet Oscar Wilde, and the famous socialite Lillie Langtry, Annie sets out to hunt down the queen's enemies--and find out why they want to kill England's most beloved monarch.
