If the leaves are falling in Sweden, it must be time for another Carol Reed adventure, and MDNA Games doesn’t disappoint once again, today unveiling the sixth installment in the series, Black Circle.

Her latest case sees the amateur detective helping out her retired doctor friend Oscar, who discovered a dead man on an early morning walk. By the time the police had arrived, however, the body had suddenly disappeared. The police don’t believe Oscar, so it’s up to players to sleuth out the truth, which naturally lands Carol "in the midst of a sinister mystery involving much more than a missing dead body.”
