He looked up into our silent, gawping faces and grinned at the sight of them.
‘It was Ref who put me right on it,’ he said, giving a last tug, ‘for he knows iron as a farmer knows rye. The iron that leaches red rot is made from bloodstone, which is the most common iron, the stuff you fish out as a bloom on bog-grass. The iron that made my nail is rare, from a dug-out stone, where it is found in little black studs, like pips in an apple.’
He moved the nail a last nudge; the key slid towards it, stopped, slid again and then snugged up next to it. No-one could breathe for the wonder of it and even the thunder did not seem as loud.
‘Ref says,’ Finn went on, half to himself as he slowly dragged his nail, the key stuck to it as tight as a resin-trapped fly, ‘that this iron embraces all the other iron it sees.’
He scooped the nail and key up and grinned at us, dangling it, swinging it gently back and forth.
‘Be happy this key is not made of gold.’
The lightning seared the image of us staring at him, fixed by the sight of that key, sucked firmly to the side of the nail. The Thunder-God boomed out a laugh.
‘There is clever for you,’ muttered Red Njal, sullenly splintering the silence that followed. ‘Can I have my binding back? There is a cold wind blowing right up the sheuch of my arse.’
Thor-light flicked us when we wraithed through the door of the storeroom; an eyeblink of stark, white light showed us the long, gentle slope up to the surface, a ramp where once barrels of salted meat and ale had been rolled. That was before Kasperick had taken the place over for his own sick-slathered pleasures.
At the top should have been a pair of double-doors, shut and barred on the outside and only fixed with chains and a lock when something of true value was inside. And guards, always guards, at least one against the pilferers when it was a store, two, I was thinking, now that it was something else. Yet they were more to prevent folk coming across what Kasperick did in his pleasure room rather than keep his prisoners getting out.
But the rain snaked in hissing waves and the two guards Kasperick had left had opened the doors and crept inside a little way for shelter; the startling flash showed them, crouched, draped in iron and rightly afraid of attracting Perun’s eye, fixed as rabbits on the stoat of Thor-lights.
No-one had to speak; Finn and Red Njal moved up like a pair of boarhounds, almost in step with one another. Red Njal’s seax gleamed briefly and one guard went sagging against him, scarcely making more than a sigh as his throat was cut.
Finn made a mess of it. Though he had done this before, his Roman nail was no edged weapon and relied on his brute strength and placing skill to tear out the voice of the guard as well as rip through the heart-in-the-throat, where life pulsed.
The guard half-turned when he saw his oarmate go down to Red Njal, a movement that put Finn’s perfect thrust off by a hair; the Roman nail ripped in and blood spurted straight back in Finn’s eyes. Blinded and cursing, he let the nail and the man go to sweep the gore away.
The nail clattered to the stone flags and the guard, his mouth opening and closing like a dying fish, staggered out into the hissing downpour, his hands clamped to his throat and blood spraying through his fingers. He could not yell and the air hissed and bubbled from his torn throat as he tried, but he reeled in circles in the rain — and someone saw him.
The yell went through me like one of Thor’s ragged blue-white bolts. Finn scooped up his nail, still cursing and sprang forward; one thrust took the nail into the gasping guard’s eye, an in-out movement that sent him backwards like a felled oak.
Too late, I was thinking as someone started smacking the alarm-iron, far too late…
‘Row for it, lads!’ roared Finn.
Make for the main gate. I heard myself screaming it like a chant and sprinted into the rain, sword out. It was not proper night and the main gate would still be open, for folk came and went on all sorts of business in a fortress such as this.
The confusion helped us. The alarm was beating, but no-one knew why, or who they were looking for and we were most of the way across the yard before I heard someone bellowing out to close the gates. I spun in a half-circle, blinking rain out of my face and saw the others closing on me. A lancing fern of blue-white fretted the dark and, in the flicker of its life, showed us to each other; the great crash that followed was a mountain falling, drowning all other sound and leaving my mouth fizzing with each ragged breath.
‘Keep Crowbone in the middle,’ I yelled and did not have to add the why of it; he was too small and light in a fight. Finn came to my shieldless side, Styrbjorn on the other and we splattered through the muddy yard — so close now, I could hear the creak and groan of bad hinging and wood as men put shoulders to the gates.
We passed them, slashing left and right and they scattered, unarmed for the most part. Styrbjorn gave a yelp as someone snarled out at him with a fistful of steel, but he took the blow on his blade well enough and back-slashed, hardly pausing at all and not bothering to see if he had done damage. Shouts went up behind us. Arrows whicked by my head and one shunked into the back of a fleeing gateman, so that Crowbone had to hurdle him.
We were through the gate, skittering on the slick, uneven log walkway and the yells were different behind us, fewer and more commanding as the garrison sorted itself out; the stark, white, flash of Thor-light sent the luckless caged leering at us as we sprinted down their avenue.
We passed two side streets; folk scattered and screamed. At the third, I yelled for everyone to go right, but I was guessing. The dark rumbled and spat white fire, while a wind sprayed rain and flattened a dying, discarded torch flame; a lantern swung and rattled.
I could not be sure and spun in a half-circle, almost falling off the walkway and the others panted up to me.
‘Which way?’ Styrbjorn wanted to know, jerking this way and that, brimming on the edge of panic. I chose one, a left turn which sloped down. Down was good. Down led to water.
There were screams and the distant clanging of the alarm; Finn growled at a head which stuck out of a doorway and the owner jerked it back again. I stepped off the walkway by accident, a long drop that jarred my foot and pitched me on my face in the clotted mat of rot, split by a running stream. Spitting and coughing, I clawed my way up and back onto the walkway.
‘They are closing,’ spat Red Njal, which made us all turn to see the dark figures moving down through the buildings. Moving fast, too.
‘Fuck,’ said Finn, disgustedly. ‘I am running from Saxlanders.’
‘Good,’ snarled Styrbjorn, shoving past him and skidding on the slick logs, ‘keep running.’
Finn smile was twisted, his face flared by another flickering message from Thor.
‘Take the boy,’ he said over his shoulder. ‘I am tired of running.’
‘Boy…’ began Crowbone, shrilling it in his anger; Red Njal grabbed him by the shoulder and shoved him after the retreating Styrbjorn.
‘It is not seemly,’ he yelled as he pushed, ‘to interrupt a man when he is dying to save you. That is not my granny’s saying, but one of my own.’
The dark shapes bobbed and lumbered down the darkness towards us and Finn glanced sideways at me.
‘This walkway is narrow enough for one,’ he grunted. ‘And high enough.’
‘Just another bridge,’ I answered and his teeth were white in the shadow of his face.
‘Bone, blood and steel,’ he grunted.
The thunder grumbled and, in the next fern of white light, I saw the Saxlanders, uneasy in their ring-coats and spears with Himself banging around the sky, throwing anger about. They milled uncertainly when the light showed two men with bright blades waiting for them.
‘Get them,’ shrieked a familiar voice. ‘Take them alive.’
