The Victorian gossipmongers called them The Petticoat Men.
But to young Mattie Stacey they are Freddie and Ernest, her gentlemen lodgers.
She doesn't care that they dress up in sparkling gowns to attend society balls as 'Fanny and Stella'.
She only cares that they are kind to her, make her laugh, and pay their rent on time.
Then one fateful night, Fanny and Stella are arrested, and Mattie - outraged but staunch - is dragged into a shocking court trial, hailed in newspapers all over England as 'The Scandal of the Century'.
