Join the Adventure Five on their most dangerous investigation yet!

When Alex, Emma, Ben, Sophie, and Jack arrive in the charming coastal village of Saltmere Bay for a peaceful summer holiday, they expect nothing more exciting than cliff walks and seaside exploration. But local whispers about the mysterious Emerald Lake-where “no one should venture after dark”-soon capture their detective instincts.

What begins as innocent curiosity about village legends quickly transforms into a heart-pounding investigation of international criminal conspiracy. Beneath the lake’s pristine waters lies evidence of systematic art theft affecting museums and cultural institutions across Europe. Professional criminals have been using local superstitions to conceal an underwater storage facility for millions of pounds worth of stolen cultural treasures.

Armed with Ben’s ingenious mechanical inventions, Emma’s systematic documentation, Sophie’s sharp observational skills, Alex’s fearless determination, and Jack’s protective leadership, the five friends must gather crucial evidence whilst evading dangerous adversaries who will stop at nothing to protect their lucrative operations.

From underwater photography missions to desperate escapes through Victorian drainage tunnels, from decoding criminal communications to coordinating with federal investigators, this thrilling adventure showcases the power of friendship, courage, and systematic investigation in the face of genuine danger.

Perfect for readers who love classic British children’s mysteries, this third installment in the Adventure Five series delivers authentic 1980s atmosphere, realistic character development, and a satisfying resolution that celebrates both justice served and friendships strengthened through extraordinary challenges.
