This "new" edition is nearly fifteen years old, and could have done with more playtesting with the first chapter, Providence, during that time. I've run this chapter several times, and, while gleefully open-ended, have found finding the information necessary to answer player questions difficult to find, as players, even moreso, may go in directions or ask for details not covered in the book. At the same time, this is my favorite CoC chapter, since it involves various NPC subplots and interactions, that, unlike too many CoC adventures, don't revolve around the scenario mystery (indeed, players may find it head-scratching that everything seems perfectly normal -- but not quite). It's almost like a game of Sherlock Holmes Consulting Detective. The Providence chapter furthermore has curious leads to the other adventures in the book, stumping players who expect clues to be neat and self-contained to the current scenario. The PDF version and printing single-sided is suggested, since this lets you cut out the handouts from the adventure text as you play; I've also used maps, background text, and pictures in the text as handouts. You can also print out only the chapters you need for your current game session. In any case, if your play group can commit to a campaign, consider this imperfect candidate.

A good campaign that's stood up well in the last twenty-odd years; perhaps better than any other classic-era (~1980s) COC sourcebook or adventure. This is the second edition, which IMO really doesn't add anything particularly useful or interesting to the original.

However, this PDF is not so great. For all that it's 55MB for 200 pages, the text is quite blurry. It's not the worst that I've bought off DriveThru RPG, but it's sure not the best either.
