When Scarlet's grandma goes into a retirement home, she
must sort through her belongings in the cramped flat above a shop
in Crouch End, north London.
Here Scarlet comes across a real treasure: a novel that
Gran wrote, imagining the life of a girl just like Scarlet,
who once upon a time lived in the flat and worked in a cakeshop
downstairs.


But as Scarlet reads about Ruby's life in Victorian London, she
begins to realise this is no piece of fiction - Ruby was
real!


A real life, facing real danger - and a mystery that unravels
to the present day.
