Do you know India Emmott?
She's about 25, has lived in London all her life, plays clarinet. Ringing a bell?
Go here for more info, see if it's the girl you're thinking of, and if it is, write about her, or your time with her, and send it to Matt Shoard (editor of Fleeting Magazine) who's putting together a biography about her. Do this by Dec 31st and it may be included in the book, The Life Of India Emmott.
The book is represented by lit agent David Miller at RCW. And I'm gonna be in it, cos I knew India once.
