This is another one-shot scenario for Trail of Cthulhu. This one is not as restrictive (or as unrelentingly grim) as The Dying of St. Margaret was, and can be played effectively as both a pulp adventure and a "purist" adventure -- though most of the material is written from the purist perspective. This scenario is a killer and most of the investigators participating are quite likely to die in the process, however intriguingly, this one is set in the Kerguelen Islands (in the far south of the Indian Ocean) and for the source material on the Kerguelens alone it is well worth $5.00. The plot is suitably mysterious complete with a secret society, Nazis and French officials, and various red herrings to drag across the players' paths. The nemesis in the scenario is horrifying and very likely (in fact almost certainly) to kill the players' characters. There are several plot hooks that can be used to get to and from this adventure, along with some nice hints that could lead to other scenarios of your devising -- if anyone survives this one, that is. It's not really intended to fit into any on-going campaign, and given the unlikelihood of survival on the part of the investigators, that's not really surprising.
As usual, DriveThru's reproduction of the book is simply outstanding. I'm giving this one a "4" overall because despite the usefulness of the backstory, the adventure itself is more suited to a convention play than an on-going play group. Still, it's as well written as most of the Pelgrane Press efforts are, and shows a loving attention to detail. All in all, well done.
