"I wouldn't leave without Freya and Frey, anyway."

Loki inspected the whole interior of the plane, asking me quick, intelligent questions about every feature of it. He seemed to grasp the design of the ship and its highly improved rocket motor almost instantly.

"You are clever, you outlanders, to devise such things," he said with sincere respect.

"Don't you want to look at the controls?" I asked.

My heart was thudding, for I had seen a wild, insane opportunity. Loki entered the cabin, and I explained the controls. Then I opened the sack of white chemicals which we always carried on these Arctic flights. I took out a handful and showed them to him.

"These are chemicals that generate heat. We use them to free the plane's wheels if they become frozen into the ice."

"That, too, is clever," he mused as he emerged from the plane. "You outlanders are indeed mechanically ingenious, though you have not probed the ancient science of the deepest forces of nature as we Aesir did."

He said nothing more as he brought me back through the laboratory to the dusky great hall. Fenris stalked at our heels. Then Loki turned.

"I could teach you our ancient science, Jarl Keith," he said, to my surprise. "You could learn much that your science puzzles over. And you would be second only to me, once the Aesir are conquered."

I began to understand what he was suggesting.
