With the release of the sixth Carol Reed mystery approaching fast, MDNA Games has now released a playable demo of Black Circle.

Her latest adventure sees the amateur detective tackling another murder mystery in Sweden. This time, her neighbour recounts a story of a dead body he discovered that somehow disappeared while he left to fetch the police. The police don't believe the elderly man's story, so it's up to Carol to get to bottom of this curious development.

The demo includes a short optional tutorial, then starts off at the beginning of the full game, introducing the mystery at hand and getting the adventure underway. To download the 89 MB file, simply head over to the game's official website.

There is no firm release date announced for the game's release, but it's expected to be available later this month.
