That spell wasn’t the work of a novice or marauding sorcerer experimenting with magic he’d found in the metaphysical section of a bookstore. Whoever had put that thing together had been a true professional, one with centuries of experience.

One who was probably more capable than I when it came to magic.

Don’t get me wrong: I’m hoss. When the spells start flying, mine are some of the flashiest, most violent on the planet. I’m like the Andre the Giant of the supernatural world. I’ve got a lot of power and mass to throw around.

Andre would be a great person to have on your side in a brawl against a rowdy tavern crowd. But in a more focused situation, he would be at the mercy of professionals who, while lacking his raw power, could nonetheless apply their own strength more efficiently and effectively. Murphy was an excellent example of that kind of fighter. She wasn’t much bigger than a bread box, but I’d seen her toss around guys weighing most of three hundred pounds like they were unruly puppies.

If the Grey Ghost was responsible for that spell, then I was lucky to have survived our first meeting. The smart move would be to scamper. If it came to a fair fight, I might find myself completely outclassed.

I felt a shivering, cold presence on the back of my neck, and turned to find wraiths nearby. They drifted toward the hideout from all directions, coming in a slow, steady procession and moving in perfectly straight lines. The siren spell made sense to me now. It wasn’t a guard spell, though it could certainly have that purpose. It was also a beacon, a dinner bell being rung to signal the mindless horde now approaching.

They never sped up, never slowed. They just kept floating forward until they began to pass through the closed steel door in groups of two and three as they converged upon it.

I pursed my lips, thinking. The Grey Ghost wasn’t killing wraiths. It was using them. For the moment, at least, there wouldn’t be any kind of guard spell on the other side of the door. There couldn’t be, or the Grey Ghost would be slaughtering its own troops and wasting its own investment of time and energy to boot.

I might have an opportunity here. The inbound wraiths would almost certainly be routed by what amounted to a cattle chute. That route would most likely be clear of supernatural booby traps. It might be possible to gain entry, find a vulnerable point along the chute, and then duck out of it to run a quick reconnaissance of the Grey Ghost’s headquarters and find Mort.

It took half an hour for the procession to be complete, and the flow of wraith traffic never let up. I stopped counting them at 450 and swallowed. That wasn’t a herd of wraiths. That was a bloody horde. If one of the wraiths decided it wanted to eat me, it would have to perform a miracle to divide me into enough pieces to feed all of its dinner company.
