This is one of several adventures written by Dian Crayne. Dian's games were originally published by Norell Data Systems. Her article, on writing adventure games, appeared in PC magazine, Volume 2 Number 4, September 1983, pp.266-276.
Very similar to other games from the same author. Even if it's a formulaic treasure hunt with some annoying (mis)features, this one has a certain interest, as it is heavily inspired on the novel by Gaston Leroux, and it has some thematic consistency as a narrative. It still keeps the same structure as Colossal Cave, which actually helps with some of the puzzles.
