Florence knows all about failure.
After a dismal end to her 2000s girlband career, she's moping around West London, single, broke and unfulfilled.
The only things she's proud of are her increasingly elaborate nail art choices - and her ten-year-old son, Dylan.But when Alfie Risby, Dylan's bitter class rival and the child heir to a frozen foods empire, mysteriously vanishes on a school trip, Dylan becomes a prime suspect.
Florence has to get her act together, find the missing boy and clear her son's name or risk losing him forever.
The only problem? She doesn't have any detective skills, she's not exactly popular at the school gates and she's just found Alfie's backpack hidden under Dylan's bed...
