Waterdeep Monkeywrench

From the introduction:

In Monkeywrench, characters are hired to make a mercenary guild look foolish. Characters have a short timeline (four days), but wide latitude in how they accomplish the job. This module includes background on the mercenary guild, a description of the mercenary guildhall, rumors that the characters can find through investigation, and two example sites guarded by the mercenaries. This adventure will challenge your group’s creativity and roleplaying ability. It is a great change of pace from classic dungeon crawls and wilderness explorations.

User summary:

For 3rd - 4th level characters.
