(I'm having second thoughts about the cultist thing, though. The probability of running into two different cells of the fuckers in the same month is vanishingly slim; and if this nonsense is a message from the same group that tried to landscape downtown Amsterdam last week, they've definitely sent the B-Team.)

I up my pace again, and just then I hear a scraping noise from the embankment to my left and every hair on my neck stands on end simultaneously.

I swing round, extending my arms in front of my face and sliding my index finger through the trigger guard as this thing clatters and scrambles down the side of the cutting in a mad dash towards me, a growl of hatred and hunger sounding an organ note deep in its chest, and I have time to think, I hate fucking dogs, just as it launches itself towards me.

I squeeze the trigger twice, aiming below where my eyes are focused on it—I can't look away; I get a flash of bared fangs and slavering tongue, eyeless and horrid and taller than any dog I've ever imagined—and there's a sound like a palm slapping a lump of wet meat as the gun kicks silently in my hand. I jump sideways as it slams into the track sleepers where I was standing a moment ago, howling a scream of agony and snapping those huge jaws at its own shoulder.

It's not a dog. Dogs aren't as black as a hole in space, and their musculature and articulation follow mammalian norms—this thing bends wrong as it bites and flails around, and I have an inkling of a memory that tells me I should be very afraid right now. But I'm not. I started out pissed off and I am now toweringly angry. Which is why I walk behind the flailing body, lower my aim towards the back of its skull, and call: "Show yourself right now, or the doggie gets it!"

There's a low chuckle. "Give us the Teapot and we will let you live, mortal."

Mortal? Yes, it's the B-Team all right; probably in robes with upside-down crucifixes or something. They're the occult equivalent of the kind of suicide bombers who post their confession videos on YouTube two weeks before they learn the hard way that trying to blow themselves up with chapatti flour isn't going to do anything except give the police an excuse to pat themselves on the back and reassure the public that Everything Is Under Control. "Come out where I can see you," I demand.
