“What is dvergr?” Curran asked me.

“Dwarf,” I told him. “Old Norse dwarf: magic, powerful, skilled with metalwork. Makers of weapons for the gods. They’re often portrayed as embodiments of greed—they lust after power, women, and most of all gold.”

“Hey now!” Dagfinn raised his hand. “Most experts believe this to be a later development. The dwarf myths probably take their root in nature spirits…”

“Dwarves like in Tolkien?” Curran asked.

I wish. I dragged my hand over my face. “One time, four dwarf brothers, the sons of Ivaldi, created some magical gifts for the gods. Two other dwarf brothers, Brokk and Eiti, became jealous of all the praise and bet Loki, the trickster, that they could make better gifts. He wagered his head. The dwarves won and then wanted to murder Loki. The gods wouldn’t let them do it, so Brokk sewed Loki’s lips shut with wire. These are not the jolly, drink-beer-and-go-on-an-adventure type of dwarves.”

“The one I met was a good guy,” Dagfinn said.

“You think the Ivar whose apprentice wore this necklace is the same Ivar who made your axe?” Curran asked.

Dagfinn nodded. “I was about fourteen or fifteen. I was wild back then, not like now.”

Curran and I looked at each other.

“So my uncle Didrik, he was a Viking, took me to the mountains to this valley. We met a smith there and my uncle talked to him and then left me there for the summer. It didn’t go well at first, but Ivar and me got along finally. I liked it there. When Didrik came to get me, Ivar made me this axe and put the runes on me. Right arm”—he slapped his right biceps— “controls the axe. Left arm is my oath. I can’t ever kill a defenseless person or force myself on anyone, or the axe will turn on me.”

“I heard you broke into the monastery looking for Asian ladies,” Curran said.

“Asian ale,” Dagfinn said. “I wasn’t looking to rape anybody. I was looking for the beer. None of them would talk to me, so I kept trying to grab them to make them hold still so I could ask where the beer was. I had a bit to drink that evening.”

The light dawned on me. “Dagfinn, they are Buddhists. They don’t brew beer. You needed the Augustine Brothers two miles to the south. You went to the wrong monastery, you dimwit.”

“Tell me something I don’t know,” Dagfinn growled. “Anyway, can I see this collar?”

We took him in to see the boy. Roderick shrank a little. “Don’t be scared,” Dagfinn said. He examined the collar for a little while and we returned to the other room. Dagfinn sat down in his chair, while Curran leaned against the wall, watching him and emanating menace.
