Set in London in the year 1811, this book tells the story of Mad Jack, who in reality is Winifrede Levering Bascombe. She arrives in London with her two aunts to beg the assistance of Lord Cliffe, Grayson St. Cyre. He welcomes the aunts, briefly spots the valet, Jack, and proceeds very quickly after their arrival to fall down the rabbit hole. He catches the valet, Jack, stealing his horse, chases Jack down, and then all sorts of interesting things happen.
