We open in media res. In a clearing in Central Park, a werewolf in the remains of a postman’s uniform is hanging on El Toro’s back. Mad Stan and Baxter are moving around in the bright moonlight trying to take down more of the beasts and protect some civilians who have gotten into the mix. I.V., reasoning that werewolves draw power from the moon, calls in cloud cover, and holds an image of the full moon on her phone to try to influence the creatures. This also plunges the entire fight into darkness, with predictable results. Lily works out that these werewolves are all from careers that carry a greater than average chance of being bitten by dogs. She manages to scratch a glyph and free one of the beasts, just before the sun rises and the remaining creatures return to their human forms, either healed, or dead.
Stan, Lily, and El Toro abscond to Stan’s Van, as they are in need to patching up. Baxter and I.V. are picked up by the police as material witnesses. I.V. is released relatively quickly, as weirdness is not grounds for incarceration. Baxter has a bit more of a time of it, but does eventually leave the clutches of New York’s Finest without picking up any new charges.
Lily calls around to the companies whose uniforms were identifiable from the monsters in the park along with the names from the badges found. She is able to narrow down the likely locus of dog biting incidents to a long block leading into Lexington Avenue on the Upper East Side. I.V., demonstrating her usual sense of self-preservation, decides that she will attempt to “Tune In” to the werewolf vibe while walking down the block. She asks someone to come along to keep her from bumping into people and Mad Stan, demonstrating his usual sense of impending doom, volunteers for the job. They spot a charming local canine bounding its way towards them down the sidewalk, dragging his person in tow.
Mad Stan has prepared for this eventuality and has a set of shaped charges in a velcro collar designed to throw silver into whatever it sticks to. After firing off a distress text to El Toro and Baxter, he flings it into Mister Tiddles’ fur in passing, resulting in a fountain of blood, a dead dog and… the malign force trailing him down the street seeking a new home. I.V. texts him to let him know he is probably possessed, which causes him to behave in an unaccountably cranky manner, but he does stop and let her catch up. She pulls him into an alleyway and using the convenient dog blood she’d just taken a bath in as ink, sets a binding for the incorporeal.
On the plus side, the binding seems to have properly set. On the minus side, the force in question now seems to be not a common case of lycanthropy but an actual demon of wrath, which is likely more powerful than a quickly sketched ward. El Toro arrives with Baxter and Lily driving around the block. Stan applies a massive effort of will and extracts himself from the ward, leaving the demon inside the wards, where it proceeds to look like escaping. As Baxter starts to drag Stan to safety, I.V., demonstrating her usual sense of self-preservation, makes the mistake of challenging the demon, giving it the chance to leap into her.
As I.V. slowly begins to show signs of possession, the group moves to the stairs of a nearby church. Stan runs inside seeking holy materials of some sort, while El Toro attempts to contain the situation. I.V. has, at this point, become rather larger and stronger than she should have been, as well as developing a slight case of being on fire, both aspects causing some damage to her companions. Baxter and Lily manage some creative parking and charge in. Lily attempts to scribe another set of banishment glyphs, but the demonic influence is able to rewrite them from under her hands and the result is an intensification of the firestorm. Stan, holy wafers in hand, tackles the possessed woman, and holds her in place as Baxter and El Toro are finally able to do enough damage to banish the demon.
Stan and I.V. must both be rushed to the emergency room, as El Toro tries to come up with some reasonable explanation for how two people came to be burned, battered, and shot.
Some weeks later, as everyone is more or less back on their feet, a tall woman in a black feathered cape walks into Kate’s and asks, “So, about my cow hides…”
