After solving The Grendel Affair, the agents have another SPI File to investigate...

We’re Supernatural Protection & Investigations, known as SPI. We battle the real monsters of myth and legend, but this Halloween, we’re searching for diamonds…

A gala opening at the Metropolitan Museum of Art has attracted the upper crust of Manhattan—and thieves. A trio of vile harpies attacks the crowd and steals the stars of the exhibition: a colorful cluster of seven cursed diamonds known as the Dragon Eggs.

In the right mage’s hands, each stone can pack a magical wallop. Together they have the power to “cure” the supernaturals of the tristate area—but for many of those vampires and werewolves, that means turning into dust.

I’m Makenna Fraser, a seer for SPI. With the help of my partner, Ian, and the other agents, I have twenty-four hours to prevent total global panic, find the diamonds, and save the supernatural community. No biggie...
