Its the old Chaosium one apparently. Never played it but tempted to get it.
They do an awful lot of odd games.

The town of Arkham, Massachusetts is in a panic. Horrific and bizarre events have begun to occur with increasing frequency - all seeming to point to some cataclysmic event in the near future that may spell disaster for everyone. Only one small band of investigators can save Arkham from the Great Old Ones and destruction!
