Again, Megan Robertson did an excellent review of this product, with which I thoroughly agree. I note in passing though, that the "see Page XX" comment could as easily be made about the scenario in the Trail of Cthulhu rule book to, and so I went to the Web Page for Pelgrane Press to see if there was any help there, only to discover a page entitled, lo and behold, "See Page XX." It appears to be an on-line 'zine containing articles of interest on the topics addressed. Additionally there are supposed to be quite a few additional handouts and documents on the Pelgrane Press site, though I have yet to figure out where they are (given the fact that I've only been looking for a brief time) and all in all it seems a clever mechanic to get you to look at their web pages for extra but unnecessary data (that is, not required to play the scenario) and simultaneously cleverly bring you face to face with their products -- thus hopefully inclining you to buy more.
So okay, it's also annoying in a way, but as noted you don't REALLY need the extra data to play the scenarios -- it's merely nice to have. Other than that, Megan did a masterful job of outlining the scenarios, and I really don't have much to add to her comments on that subject.
As usual, DriveThru did a magnificent job of reproducing the book and everything in my copy was highly legible and useful. All in all, this one earns a richly deserved "5."
