The mission: Your story in Haarlem

You are a Dutch cultural-property investigator joining veteran detective Ken Clever in Haarlem after a scorched restoration certificate surfaces alongside several suspicious Golden Age paintings. 

A hidden registry code leads to altered ledgers, forged paperwork, and conflicting accounts across the city. Follow the clues, expose the network hiding behind Haarlem's historic facades, and uncover the truth behind the masterpieces that never existed.
