First off, the title of this one is pretty misleading. In point of fact, all the adventures are at least initially set in NYC, not Arkham. Nor is there any apparent connection with Arkham in the scenarios. All in all, the title is definitely a case of false advertising.

Second, a warning, this is not a Classic "Call of Cthulhu" product. Instead it is based on the Gumshoe system with CoC elements liberally used as the basis. The primary difference between this system and CoC is that the players WILL find the necessary clues to ensure the advance of the game. Actually, I'm not sure that concept required an entirely new game system to be applied, but whatever.

The scenarios are well designed, and the clues (which the players will automatically get, given enough time) are scattered around sufficiently to require the players to pursue multiple lines of inquiry to collect all the data (which is what "investigators" worthy of the name OUGHT to be doing regardless). As previously noted, the adventures are all set in New York City, but there are several opportunities to go pretty far afield (and a wily Keeper can probably create a few more). The scenarios all seemed pretty interesting and able to keep the players involved. The plot details are a bit on the "stock" side -- typical for Cthulhoid menaces; but there are a few unexpected twists and turns that will force the players to stay on their toes. While I am frankly much more interested in CoC than I am in ToC, I invariably find the scenarios and plot details in ToC to be well crafted, well thought out, and very usable in a traditional CoC game. Indeed, as previously noted, I usually use some of the mechanics of Gumshoe to ensure my players get the "absolute must-have" clues anyway, all without requiring either them or me to go through a completely new game system to achieve it. Given the multiple lines of inquiry they can pursue in these scenarios, most players shouldn't feel too railroaded by the scenarios, even though they will all wind up at the same place sooner or later. If the Keeper really wants to be nefarious about the whole thing, he can even arrange to have a couple of these scenarios (especially "The Kidnapping" and "Return to Red Hook") serve as red-herrings for each other and even unfold simultaneously, leading to a great deal of confusion and some excellent role-playing opportunities for the players.

As always, the reproduction of the document by DriveThru is outstanding, with excellent production quality all around. Indeed, the only odd thing is that they felt it necessary to split off the cover and download it as a separate file. I'm not sure precisely why simply "zipping" the entire file wouldn't work to ensure quicker download and less file space, but I imagine they must have had a reason for it. Overall, I rate this one a solid "4" due to production quality, the in-depth nature of the designs and the high-quality of the reproduction.
