About This Game

Delphine and Cynthia return in a Cold War Mystery

Investigate what happened to your friend Arthur Birdwhistle, a highly decorated MI6 officer who has vanished without a trace. He was last heard from in a phone box in West Berlin. The morning after the president died. The call was cut short.

Green Mist over Portland is the sequel to The Red Pearls of Borneo. Play as two women on opposite sides of the same investigation: Delphine, the clairvoyant who can step into the past and witness events as they happened and Cynthia, the MI5 field agent who must interrogate suspects and discover clues deep within the MI6 secret archives.

The investigation will take you on a globe-trotting adventure following a trail of spies from a quiet English harbour town to a frozen Finnish fishing village and the corridors of an intelligence service rotten at its core.

Inspired by Return of the Obra Dinn, The Case of the Golden Idol and The Roottrees Are Dead
