On the surface, the module looks quite good and the premise is interesting. However, now that I am running the SAS in my chronicle, I can say that it doesn't stand up too well to actual game-play.
There are a lot of assumptions about the behavior of the PCs and the plot doesn't stand up too well under scrutiny - in fact as the representation of vampiric machinations, it lacks a lot of depth.
The scenes do need a lot of work to ensure that they don't look contrived, and I think that any group of experienced players will take this module well 'off the rails' very quickly (not that it's a bad thing, but an ST needs to be ready for this).
If you have the time to tweak this SAS, then it could be salvaged, but as a 'quick play' it is best avoided.
