I really liked this adventure, and the fiction was also very enjoyable. The lovecraftian horror elements translate very well. Of course, both settings being horror-based, it's like translating between English and Australian.
The guide to translating characters to old Call of Cthulu is... mercifully brief, but workable. Just not of real use to me.
My highest compliment, as a somewhat cruel GM, is that I would enjoy running this in one of my games.
