Aunt Enid's back, but something's changed... A deal with fairies... to solve a mystery... and prevent a war. Fairies and magic: It's all real! Enid Turner is invited to a picnic in honour of the creator of the world's most famous detective, currently on a lecture tour in Adelaide, where they are caught in a web of treachery and betrayal from the Otherworlds. It's up to Aunt Enid and the Protectors, with a little help from the self-appointed Fairy Hunter, to solve the mystery, return the kidnapped heir and save the humans from Otherworldly retribution. It's now a race to save the Earth from becoming a battleground for a magical war.
