spoiler alert This short adventure takes place in the City of Specularum in the Grand Duchy of Karameikos. Of course, it can be set in any other campaigns where there is a city big enough to host three influencial families deeply involved in politics. The adventure starts with the characters entering Specularum and witnessing an argument during a parade that could lead to a violent conclusion. The characters can then be hired by one of the factions (families) to hinder the other two. However, one the families is secretly leading an organization called The Veiled Society: masters extortionist and sometimes murderers. Different events are provided to get the characters involved into the adventure and depending on their choices, they may end up helping the veiled society or destroying then and the Radu family leading them. The background for the events is the murder of a girl from another family.
The adventure is not bad per se and offers quite a change compared to the other adventures so far which were mostly about dungeon crawling. The events are varied and enough content is presented to expand the adventure beyond its low page count.
However, there are some flaws that would require a bit of work on the GM's part. First is the incentive for the characters to get involved. Besides getting paid, they do not have a lot to hook them in. Secondly, the duke and his soldiers seem not only inefficient, but they are barely present. The characters get a chance to oppose the soldiers, but not to collaborate with them. Considering a rather important noble was murdered it seems weird not to have a chance to investigate on behalf of the law rather than being hired privately.
Again a good GM can fix this, but to provide what I think is a fair review of that module such as it is, I would say it is an ok module.
