Lade Livestone, a venerable grocer, has long abandoned his hopeless war with his eternal enemy, the all-powerful Leviathan, but the ghosts of the past still appear on the threshold of his shop from time to time. Ghosts that he would be better off driving away, but... Sometimes even tigers tend to show weakness. This time he will have to deal with an unusual client. It is not the victim of a bloodthirsty monster who asks for his help, nor the unlucky simpleton who had the imprudence to enter into an agreement with one of the Nine Unknowns. Something evil is happening under the roof of a powerful and wealthy stock exchange company, one of the financial pillars of New Bangor. And although Lade Livestone, an honest merchant, always despised this crowd in smart suits, and there seems to be no reason to be afraid, perhaps this matter is worth taking a serious look at. Who knows, maybe its audit will reveal much more dangerous things than a couple of overdue bills and accounting errors?..
