Long Rufus Rafferty
The leader of the Summat Dreadful Gang, which controls the entire neighborhood of Eldersden in Pell, and as such, he controls the prostitution ring that runs there.
It's unclear where Rafferty originally hails from, whether he's from Pell or elsewhere, and it's more unclear what he did prior to his rise in power in Eldersden. During the period following Allan Seabairne's apparent death, Rafferty surfaced and used drugs to gradually take control of Eldersden away from the girls and to himself. He gathered himself manpower to enforce his rule, and keep the girls in line, until the only women in Eldersden who didn't follow his orders were the 'Mistresses,' who run a more... specialized type of service.
Rafferty has an amicable relationship with Joss Nathan, and one with Steve Varrius prior to the man's death at the hands of Seabairne. Rafferty is probably aware of Seabairne's return, but he has as yet made no statements about his views on it.
