***This review contains spoilers****

This short adventure is intended challenge characters of 1st. A logging company is looking for a group of adventurers to investigate a series of mysterious happenstance at one of their logging camps and determine if the site can be reclaimed. The city in which the adventure begins does not have stats and the trip to the woods where the survivors of the incident are encamped is not covered, but a random encounter table is provided. I do not see this as a flaw because the adventure does not take place in the city and the trip can be as long as you want it to be. Deadly Delves are intended to be short and to the point, so there is no sense in adding that much details. You can create them as you see fit. It also allows a GM to place the adventure anywhere in his campaign as long as there some logging going on.

After meeting with the foreman of the camp to gather more information about what happened, a half-day journey takes the characters to the abandoned site of the former camp and with a little investigation, they can find tracks leading deeper in the woods. Since it is a logging camp, many tracks will lead to the forest and back to the camp. The odd thing here would be that these tracks originate from the camp's smithy. That could be seen as a minor flaw in the plot since this clue may be overlooked by players, but I do not think it would impact the adventure that much as any capable GM can get the players to follow these tracks with a few additional clues.

Following the tracks will lead the party straight into an ambush. If the characters do not kill outright the men assailing them, they will learn a lot of invaluable information about the who is behind these strange occurrences and where to find their lair. Even if the trappers get killed, the party can follow their tracks back to the caves where they lair and where lives the main antagonist. The cave system is the former lair of coven of troll witches, and as such, they left some traces of their occupation as well as a few unpleasant surprises. While exploring the caves, the characters can confront the huldra behind all the occurrences and figure out the fate of the missing loggers. Several scenarios are provided based on how the group meets the huldra and how they resolve the situation; some of these include peaceful solutions which I find very refreshing from most nodules I read.

Overall, I really liked this module as it is challenging, but all challenges require brute force and spells. The fact that it can be resolved peacefully and that the dangerous areas do not need to be explored makes it a great module for 1st level parties. I did njot get a chance to playtest it, but it seems well balanced. No suggestion were provided to expand the module or create other adventures based on this story, but I do not feel like it diminishes the quality of the module. I really, really liked that it can be resolved without much bloodshed if your players are so inclined.
