"Snorri Hengest died here." Tuttugu from the prow. "We should see Skilfar. She'll know of a better way. n.o.body comes here, Snorri. It's a bad place."

"We're looking for a bad thing."

And that was that. We kept going.

"So, who was Eridruin?" Sailing on a fjord is infinitely preferable to sailing on the sea. The water stays where it's put and the sh.o.r.e is so close that even I might make it there if it came to swimming. This said, I would rather be sailing over rough seas away from any place famed for monsters than sailing toward it on the flattest of millponds. "I said, who was-"

"I don't know. Tuttugu?" Snorri kept his eyes on the left sh.o.r.e.

Tuttugu shrugged. "It must ache Eridruin's spirit to be famed enough for his name to survive but not quite enough for anyone to remember why they remember it."

A stiff breeze had carried us inland. The day kept grey, the sun showing only brief and weak. By late afternoon we'd covered perhaps thirty miles and seen no sign of habitation. I had thought Harrowheim's raiders came from further up the fjord, but n.o.body lived here. Tuttugu had the right of it. A bad place. Somehow you could tell. It wasn't anything as simple as dead and crooked trees, or rocks with sinister shapes . . . it was a feeling, a wrongness, the certain knowledge that the world grew thin here, and what waited beneath the surface loved us not. I watched the sun sinking toward the high ridges and listened. The Harrowfjord wasn't silent or lifeless, the water lapped our hull, the sails flapped, birds sang . . . but each sound held a discordant tone, as if the skylarks were just a note away from screaming. You could almost catch it . . . some dreadful melody played out just beneath hearing.

"There." Snorri pointed to a place high upon the stepped sh.o.r.e to our left. Like a dark eye amid the stony slopes, Eridruin's Cave watched us. It couldn't be any other.

The Nors.e.m.e.n lowered the sails and brought us into the shallows. Fjords have deep shallows, diving down as steeply as the valleys that contain them. I jumped out a yard from the sh.o.r.e and managed to wet myself to the hips.

"You're just going up there . . . right now?" I looked about for the promised monsters. "Shouldn't we wait and . . . plan?"

Snorri shouldered his axe. "You want to wait until it gets dark, Jal?"

He had a point. "I'll guard the boat."

Snorri wound the boat's line around a boulder that emerged from the water. "Come on."

The Nors.e.m.e.n set off, Tuttugu at least looking as though he would rather not and casting glances left and right. He carried a rope coiled many times about him, and two lanterns bounced on his hips.

I hurried after them. Somehow I could think of no horror worse than being alone in that place, sitting by the still water as the night poured down the slopes.

"Where are the monsters?" It wasn't that I wanted to see any . . . but if they were here I'd rather know where.

Snorri paused and looked about. I immediately sat down to catch my breath. He shrugged. "I can't see any. But then how many places live up to their reputation? I've been to plenty of Giant's This and Troll's That, without a sniff of either. I climbed the Odin's Horn and didn't meet him."

"And the Fair Maidens are a great disappointment." Tuttugu nodded. "Who thought to set that name on three rocky isles crammed with ugly hairy men and their ugly hairy wives?"

Snorri nodded up the slope again and set off. In places it was steeper than stairs and I reached out ahead of me, clambering up.

I climbed, expecting attack at any moment, expecting to see bones among the rocks, drifts of them, tooth-marked, some grey with age, some fresh and wet. Instead I discovered just more rocks and that the growing sense of wrongness now whispered around me, audible but too faint to break apart into words.

Within minutes we stood at the cave mouth, a rocky gullet, fringed with lichen above and stained with black slime where the water oozed. Twenty men could march in abreast, and be swallowed.

"Do you hear it?" Tuttugu, more pale than he had ever looked.

We heard it, though perhaps the cave spoke different words to each of us. I heard a woman whispering to her baby, soft at first, promising love . . . then sharper, more strained, promising protection . . . then terrified, hoa.r.s.e with agony promising- I spoke aloud to overwrite the whispers. "We need to leave. This place will drive us mad." Already I found myself wondering, if I threw myself down the slope would the voice stop?

"I don't hear anything." Snorri walked in. Perhaps his own demons spoke louder than the cave.

I took a step after him, out of habit, then caught myself. Fingers in my ears did nothing to block out the woman's voice. Worse, I realized there was something familiar about it.

Snorri's progress slowed as the cave floor sloped away, as steep as the valley behind us, but slick with slime and lacking handholds. The gradient steepened further, the cave narrowing to a black and hungry throat.

"Do not."

A tall man stood between Snorri and me, in the shadow of the cave, in the s.p.a.ce through which Snorri had just walked. A young man, clad in a strange white robe, sleeved and open at the front. He watched us through stony grey eyes, unsmiling. All the other voices retreated when the man spoke-my woman with her dead child, and the others behind her, not gone but reduced to the pulsing hiss you can hear in a seash.e.l.l.

Snorri turned, taking the axe from his back. "I need to find a door into Hel."

"Such doors are closed to men." The man smiled then-no kindness in it. "Take a knife to your veins and you will find yourself there soon enough."

"I have a key," Snorri said, and made to resume his descent.

"I said, do not." The man raised his hand and we heard the bones of earth groan. Plates of stone shattered away from the cavern roof, dust drifting in their wake.

"Who are you?" Snorri faced him again.

"I came through the door."

"You're dead?" Snorri took a step toward the man, fascinated now. "And you came back?"

"This part of me is dead, certainly. You don't live as long as I have without dying a little. I have echoes of me in Hel." The man tilted his head, as if puzzled, as if considering himself. "Show me your key."

"Who are you?" Snorri repeated his first question.

Across from me Tuttugu stopped pressing the heels of his hands to his ears. His eyes widened from the slits they had been. He grabbed up his axe from the rocks and crawled to my side.

"Who? Who was I? That man is dead, an older one wears his skin. I'm just an echo-like the others echoing here, though my voice is the strongest. I am not me. Just a fragment, unsure of my purpose . . ."

"Who-"

"I won't bandy my name before a light-sworn warrior." The dead man seemed to gather himself. "Show me your key. It must be the reason I am here."

Snorri pursed his lips then released one hand from the axe to draw Loki's key from beneath his jerkin. "There. Now, if you won't help me, shade, begone."

"Ah. This is good. This is a good key. Give it to me." A hunger in him now.

"No. Show me the door, ghost."

"Give me the key and I'll allow you to continue along your path."

"I need the key to open the door."

"I thought that once. I had many failures. I called myself door-mage but so many doors resisted me. The key you hold was stolen from me, long ago. Death was the first door I opened without it. Some doors just require a push. For others a latch must be lifted, some are locked, but a sharp mind can pick most locks. Only three still resist me. Darkness, Light, and the Wheel. And when you give me the key I will own those too."

Snorri looked my way and beckoned me. "Jal, I need you to lock the door after me. Take the key and give it to Skilfar. She will know how to destroy it."

"I have something you want, barbarian."

The door-mage had a child at his side, gripping her neck from behind. A small girl in a ragged woollen smock, bare legs, dirty feet, her blond hair thrown across her face as the man forced her head down.

"Einmyria?" Snorri breathed the name.

In one hand the child held a peg doll.

"Emy?" A shout. He sounded terrified.

"The key, or I'll break her neck."

Snorri reached into his jerkin and tore the key from its thong. "Take it." He strode forward pressing it carelessly into the mage's hand, eyes on his daughter, bending toward her. "Emy? Sweet-girl?"

Two things happened together. Somehow the mage dropped Loki's key, and in reaching to catch it as it fell he let go of the child's neck. She looked up, hair falling to the sides. Her face was a wound, the dark red muscle of her cheeks showed through, stripped of skin and fat. She opened her mouth and vomited out flies, thousands of them, a buzzing scream. Snorri fell back and she leapt on him, black talons erupting from the flesh of her hands.

I glimpsed Snorri amid the dark cloud, on his back, struggling to keep the child-thing from ripping out his eyes. Tuttugu lumbered forward, shielding his face, swinging his axe in an under-arm looping blow. Somehow he missed Snorri but caught the demon, the force of the impact knocking her clear. For a second she scrabbled at the muddy slope, shrieking at an inhuman pitch, then fell away, wailing, into the consuming blackness. The flies followed her, like smoke inhaled by an open mouth.

With that deafening buzz receding I noticed the laughter for the first time. Looking away from the cave's throat I saw that the mage remained crouched on the ground, the key still before him on the rock. He wasn't looking at Snorri, just the key. He tried again to pick it up but somehow his fingers pa.s.sed through it. Another awful, bitter laughter broke from him, a noise that ran through my teeth and made them feel brittle.

"I can't touch it. I can't even touch it."

Snorri scrambled to his feet and rushed the man, throwing him back with a roar. The mage went tumbling, fetching up hard against a rock. Snorri scooped up the key and rubbed his shoulder where he'd barged his foe aside, an expression of disgust on his face, as if the contact sickened him.

"What have you done with my daughter?" Snorri advanced on the mage, axe raised.

The man didn't seem to hear. He stood, staring at his hands. "All these years and I couldn't pick it up . . . Loki must have his little jokes. You'll bring it to me though. You'll bring me that key."

"What have you done with her?" Snorri, as murderous as I'd ever heard him.

"You can't threaten me. I'm dead. I'm-"

Snorri's axe took the man's head. It hit the ground, bounced once and rolled away. The body remained standing for long enough to ensure it would feature in my nightmares, then toppled, the neck stump bloodless and pale.

"Come on." Snorri started to climb down the cave's black gullet, backing into it on all fours, feet first, questing for edges to hold his weight. "Leave him!"

I turned away from the remains of the man, the ghost, the echo, whatever it was.

The whispers rose again. I could hear the woman crying, the sound rasping on my sanity.

"Jal!" Snorri calling me.

"I said, do not!"

I turned, looking for the voice. My eyes settled on the severed head. The thing was staring at me.

I struggled to speak, but a voice deeper than my own answered instead. Somewhere deep below us the earth rumbled, the sound of stones that had held their peace ten thousand years and more now speaking all at once, and not in a whisper but a distant roar.

"What?" I looked to where Snorri hung, confusion on his face.

"Better run." The head spoke from the floor, lips writhing as the words sounded inside my skull.

The roar and rumble of falling rock rushed toward us, rising from deep below, a terrible gnashing, as if the intervening s.p.a.ce were being devoured by stone teeth.

"Run!" I shouted, and took my own advice. My last glimpse of the cave showed me Tuttugu running my way and Snorri behind him, still trying to haul himself clear of the drop-off.

I sprinted out beneath the hanging lichen and recoiled off Tuttugu as our paths crossed. The impact sent me sprawling and probably saved my life as my terror would have seen me racing out onto a killingly steep descent toward the fjord.

"Quick!" I wheezed the word while trying to haul air back into my recently emptied lungs.

Tuttugu and I staggered out onto the slope, clinging to each other, a rolling cloud of pulverized stone billowing behind us. We fell to the ground and looked back as the cave exhaled dust, like smoke whooshing from the mouth of some vast dragon. Buried thunder vibrated through us, resonating in my chest.

"Snorri?" Tuttugu asked, staring at the cave mouth without hope.

I made to shake my head, but there, emerging from the cloud, grey from foot to head, came Snorri, spitting and coughing.

He collapsed beside us, and for the longest time none of us spoke.

Finally, with the last traces of dust drifting out across the water far below, I stated the obvious. "No key in the world is going to open that for you."

EIGHT.

We returned to coast-hopping, the Norseheim sh.o.r.e leading us south. Given that Snorri's options appeared to have reduced to the wastes of Yttrmir in the distant and unwelcoming kingdom of Finn, or a poisoned lake in still more distant Scorron, he settled for seeking out Skilfar as originally planned, his quest so far having added only questions rather than answers.

Aslaug came to me that first night, just as on the previous one on the fjord while we sailed away from the collapse of Eridruin's Cave, and warned me against the Norseman's plans.

"Snorri is led by that key and it will be his ruin, just as it will ruin any who keep his company."

"They say it's Loki's key," I told her. "You don't trust your own father?"

"Ha!"

"Can't the daughter of lies see through her father's tricks?"

"I lie." She smiled that smile which makes a man smile back. "But my lies are gentle things compared to those my father sews. He can poison a whole people with four words." She framed my face with her hands, her touch dry and cool. "The key is locking you in to your fate even as it opens every door. The best liars always tell the truth-they just choose which parts. I might truthfully tell you that if you fight a battle at the equinox your army will be victorious-perhaps though, your army would have won on every day that month, but only on the equinox would you not survive the battle to see the enemy routed."

"Well, believe me when I say I'm stopping in Vermillion. Horses, wild or otherwise, couldn't drag me to Kelem's doorstep."

"Good." Again the smile. "Kelem seeks to own night's door. It would be better it were never opened than that old mage gain control over it. Get the key for yourself though, Prince Jalan, and you and I might open that particular door together. I would make you King of Shadows and be your queen . . ."

She broke apart in the gloom as the sun set, her smile last to depart.
