At the Wings & Co. Fairy Detective Agency, Emily Vole and her friends are beginning to worry.

It's five months since their official opening and they still haven't had one case.

Then local landowner Sir Walter Cross dies suddenly and mysteriously.

The detectives suspect fairy meddling. And when Mr Rollo the tailor mysteriously loses everything and Pan Smith's wedding plans are ruined the night before her big day, they're convinced there must be magic at play.

Now they have not one, but three pickled herrings to deal with!

Can they solve the mystery of who is stealing people's luck before the meddling fairy goes too far?
