Join the Locke family and their friends as they explore landmarks in their new home of Lovecraft, MA. Find and use powerful keys, make powerful allies, and put together the pieces of the past. But beware - not everyone is who they appear to be! Demons may be hiding among the group, enacting their own devious plans. Shadow of Doubt is a race to root out the traitors before they can open the Black Door and unleash a horde of demons upon the world!
Based on the award-winning graphic novel Locke & Key by IDW Publishing, Shadow of Doubt is a light, snappy social deduction game that's dripping with theme.
