"Very therapeutic, I'm sure," Molly said kindly. "But that was never going to work. Also, I feel I have to point out that such a blatant attack on the shield is almost certainly going to tell everyone in Area 52 that we're here."

"They know we're here," I said. "Methuselah will have told them by now. But if my armour can't break this shield, and your magics can't even touch it, how the hell are we going to get through?"

"We could tunnel under it," Molly said brightly. "Or rather you could; I don't do manual labour."

"You don't even do dusting," I said. I looked thoughtfully at where the field should be. "Has to be a way in… We didn't come all this way just to be stopped by a stupid force shield."

"Right," said Molly. "So do something, Eddie!"

"I'm thinking!"

I pulled out the Merlin Glass. It nestled comfortably into my armoured hand, still showing a snowy scene very different from the one before me, and still subtly urging me on. I weighed the Glass in my hand, and then stepped forward and slapped it hard against the force shield. The Glass hung in midair, shaking and shuddering, and then it grew suddenly in size to a doorway, breaking through the shield by making itself part of the shield. I took Molly by the hand and led her through, and then the doorway slammed shut behind us and the Merlin Glass shot back into my hand, like an obedient dog. I put it away, and set off again, with Molly just a few steps behind me.

"You're so sharp you'll cut yourself one of these days," she said finally.

"I'm sure you'd have thought of it," I said generously. "Eventually."

We headed on across the great plateau of snow and ice, stopping occasionally so I could take out the Merlin Glass and use it like a compass, to make sure were still heading in the right direction. Still no sign of Area 52, or anything like an entrance. We'd been walking for almost an hour now, though I had to check my armour's internal clock to be sure. With so few real landmarks, it was hard to be sure of space or time. I was growing dangerously tired. I'd done so much today, and there was still so much more to do. And then I stopped suddenly, and looked sharply about me. Molly hovered beside me, her eyes bright and alert.

"You feel it too," she said. "We're not alone. I can't See anything, but I can feel it, in my bones and in my water. Something else is here with us, and it knows we're here. It's watching us."

"Guard dog," I said flatly. "Has to be. If you had a secret base set up here, you'd invest in a guard dog or two, wouldn't you? But what kind of creature could survive on its own, in this environment? Without my armour and your protections, we'd have been dead within minutes of arriving. So whatever it is… would have to be seriously tough and nasty, able to survive where nothing else could. Feel free to disagree with me, Molly, because I am starting to depress myself…"

"Wendigo?" said Molly, looking quickly about her. "Giant polar bears? Didn't Superman have some of those guarding his secret fortress in one of those films? Or did I just dream that?"

"I did once send a Russian werewolf here," I said thoughtfully.

"You've lived, haven't you, Eddie?"

And that was when the robot guard dog erupted from under the snow right in front of me, a huge steel shape with glowing red eyes, snapping steel teeth and flailing steel claws. It hit me hard in the chest, throwing me backwards, and I had to struggle to keep my feet under me. It was bigger than me, and heavier, a huge steel hound with moving parts showing clearly through its latticeworked steel hide. It clung to me, scrabbling at my shoulders with its fore-paws, whilst its lower paws came up to claw at my belly, trying to disembowel me. Steel claws scrabbled uselessly against my golden armour, while steel teeth shattered and broke on my golden throat. I grabbed the guard dog by the forearms, and forced the snapping steel jaws away from my face.

Molly darted back and forth around me, trying for a clear shot, and yelling what she thought was helpful advice. I concentrated on forcing the killer robot dog away from me, until finally it hung helplessly in my grasp, the lower legs still scrabbling for something to attack. And then I tore the dog apart, first limb from limb, and then piece by piece, until there wasn't enough left of it to function. It lay scattered across the snow, just so many intricate steel parts and glimmering tech, still moving and twitching as the last of its energy ran out. The red glowing eyes took a long time to fade away. I knelt down and studied the mess thoughtfully, while Molly floated at my side.

"This wasn't just some stupid robot," I said finally. "There was definitely intelligence at work. Primitive AI. I should have tried to communicate with it."

"Like what?" said Molly. "Down boy? Stop trying to kill me? Good dog?"

"How long was it lying here, under the snow?" I said. "Waiting patiently in the dark, for months or maybe even years… For something, anything, to come along? And when someone does turn up, all its programming will allow it to do, is attack. Was it lonely, do you think? Poor thing. Poor doggie."

"Poor doggie?" said Molly. "It would have quite happily ripped us apart, and probably pissed machine oil on our bits and pieces afterwards. Honestly, Eddie, you can get sentimental about the strangest things."

I stood up. "I'm surprised there aren't more of the things. Who bets all their money on a single guard dog?"

Molly shrugged. "Too expensive, probably. Did you see that tech? Alien derived. I'm betting they found the original and then reverse engineered it into a guard dog."

"Poor doggie," I said. "When this is all over, I think I'll come back and collect up the pieces. The Armourer will have a great time putting it back together again. He's always wanted a pet that didn't die easily."

Molly rolled her eyes at the heavens. "Look-all of this is just slowing us down. We have to move faster than this!"

"All right," I said patiently. "What have you got in mind?"

"Oh right, put the pressure on me! Leave it to me to come up with something to save the day!" She scowled heavily. "There's any number of magics I could use here, or at least tap into, but I can't help feeling I'm going to need every nasty spell I've got, once we're inside Area 52. That business at Castle Frankenstein took a lot out of me, and I'm nowhere near back to full strength."

"What about what happened at the Hall?" I said carefully. "Are you fully recovered from that?"

"It's sweet that you worry about me, Eddie, but stop it or I will slap you. I'm fine. Really. In fact, I can't wait to get this all over and done with, so I can get you back to our bedroom and show you just how fine I am."

I grinned. "You do know how to motivate a man." And then I broke off and looked sharply around. "Hold everything; I think it's time for round two."

A mist formed around us, grey tendrils coalescing out of the cold air, thickening into a grey sea of churning, roiling mists, that cut us off completely from the rest of the world. Sounds became increasingly distant and diffuse, as though we were underwater. Or as though the world was drifting farther and farther away. Molly and I moved instinctively to stand back to back, searching about us for some sign of an enemy. The thick grey fog had an unnatural chill to it, that made me shudder even inside my armour.

"Unnatural," I said, just to show I was keeping up.

"Very," said Molly. "Look! You see that?"

I did. Dark shapes were moving in the fog, circling slowly, keep ing their distance for the moment. Their movements were awkward, strange, not human, for all their basically human shape. I tried counting them, but the number always came out different, as though they were fading in and out. Over a dozen, certainly, maybe twenty. There was something horribly abstract about them; their details kept changing, like the menacing shapes we see in dreams, or just briefly out of the corner of an eye. My skin crawled under my armour, and sweat ran down my face. I could hear Molly breathing heavily behind me, feel her back shaking where it pressed against mine. The shapes circled faster and faster, closing in on us from every direction at once.
