The Portrait Job

From the introduction:

The crew receives the summons to their briefing just after sunset, bidding them to come to the Greywater District, a slum that is loosely considered to be Circle turf. The meeting takes place in the basement of a rundown alehouse, where they are met at the door by a scarred Vladov bouncer; as the crew passes through the common room, surly faces and suspicious eyes follow them to the stairs leading down to the cellar. There, they find an underground fighting ring set up in the dirty, emptied out basement, where the sounds of fists and feet hitting flesh serve as the backdrop for the meeting.
