Seek and Destroy

From the front of the book:

It's time to finish the job you and the Sand Kings have started: the infiltration and assassination of a major Netherese agent. But is a direct assault the best path to take – both literally and morally? A Living Forgotten Realms adventure set in Netheril for characters of the Paragon tier (levels 11-20). This adventure is the third and final part of the Sand and Shadows Major Quest, which began with NETH3-1 and continued with NETH3-2. We strongly recommend that you play the three parts of this series in order, with the same character, if possible.
