A rich landlord finds out tenants are abandoning his apartment buildings. No one will tell him why, but there are whispers of old gods – the numina – who came alive and now take residence in the buildings.
Enter Felix, a professional fox. Dressed in a toga and armed with a dagger, Felix is hired to sniff out the truth. He must separate fact from superstition – a hard task in a world where the old gods still roam the earth.
