This was a Salt Lake City, UT based company. Angel in the Attic appears to be their only published game. Their website has expired and been purchased by another company, but you can still see their original site using the Way Back Machine at archive.com
The company was founded by a Christian family who enjoyed playing the board game Clue but did not enjoy the murder mystery theme. The mother of the family, Barbara Fallick, created Angel in the Attic as a Clue variant using a family friendlier theme of searching for lost nativity set pieces.
According to the way back machine, the company website existed until June 2002. The website, http://www.angelintheattic.com/ is currently owned by an unrelated Texas company.
