The Charlie Muffin Thriller series (Sawbridgeworth CM21)

I got to reading this series after the author's death last year. Unfortunately the Herts Libraries e-books run out at book 6.

I would love to read books 7-16 (!) but can't find them anywhere. (HCC half-heartedly agreed to consider sourcing the rest but haven't come through - I've even appealed to the publishers with no success).

If anyone has them lying around on their bookshelves, I'd love to read them.
