4 out of 5 rating for Murder in Baldur’s Gate
First off, don't pay $35 for this. Amazon has it for much less. Second, be sure to track down the two online-only PDF supplements on the WoTC website (one with monster stats, one with extra material for the adventure). Third, this is really two products. A setting guide and maps for Baldur's Gate, and an adventure to run in it. I found the setting part much more useful. The adventure is a good alternative to dungeon-based, politics-free campaigns, but it has a lot of moving parts that the DM has to keep track of. Be prepared to do a LOT of homework running this adventure. Overall, the product is a solid B+.
