Vampire: The Overseer, Brujah 2

Immortal bampires lurk in the modern nights, hidden from the eyes of mortals by an elaborate masquerade and the traditions of their sect, the
Camarilla. Enforcing these laws is Theo Bell, archon, enforcer and executioner among the undead.
But Theo may have bitten off more than he can chew. The Minneapolis slave ring has been destroyed and its captives rescued, but his problems are just beginning. The slave trade is widespread, and it threatens to blow apart the entire masquerade. He urgently needs to track down whoever is responsible and put them out of business, but he is assailed by treason and demands more close at hand. All the while the Overseer, the deadly agent of the hidden slave masters, has Theo in his sights.
