The Weeping Widow

From the publisher's website:

The Weeping Widow is the sort of tavern where a lot of trouble can be found in a short amount of time. It is run by a vindictive sailor’s widow who is out to hunt down the people she feels responsible for her husband’s death. To that end she will work with anyone and everyone who can help her. But her criminal connections and bribes to the city guard have not gone unnoticed and there are some lines she will not cross.
