Very much a setting for adventures than a true adventure module, The Secret of Bone Hill basically details the southern part of the island of Lendore, centred around the town of Restenford in the world of Greyhawk. Near this town there’s a couple of dangerous places, foremost among them Bone Hill, which has a fortress inhabited by bugbears during the day and undead during the night. 

Most of the 30 page module consists of detailed descriptions of these locations and their inhabitants as well as treasures and monsters to be found. What the module does not really have, however, is a plot to go with it. In fact it hints at further developments in L2 and further on, but doesn’t really give a clue to the DM as to what they might be. So this module really relies on the DM to make up a story to go along with the detailed setting, but with no inkling as to what will happen in the module series that is a hard task if you want to move on to L2 later on. 

Weirdest of all the module includes detailed descriptions of the large Restenford castle while also saying that players have no reason to go in there until at least L2… so the following module. Why is this here then? Shouldn’t it be in L2? Maybe Lakofka is just trying to cover all the bases, seeing as even if there is no reason to go in the castle there is the possibility to go into the castle as you are in that town, but surely there are ways to block access until L2. Oh well. A bit of a weird one this module, but at least it introduced the Beholder’s nicer cousin, the Spectator to AD&D.
