"I can overtake them in a few minutes," I said grimly. "You Aesir may know a lot about atomic fires and subtle forces, but you don't know airplanes. Mine is moored right on this beach."

"Your flying ship?" he gasped. "I had forgotten about it. Is it swift enough to overtake the Jotun ships?"

"Swift enough?" I repeated. "Wait till you get in it. Maybe it'll make you think a little more highly of my science!"

I hastened toward the two great boulders between which I had moored my plane. It was gone! The tracks in the sand showed that it had been dragged down to the water.

"Someone's stolen my ship!" I groaned.

"The Jotuns must have done it. Whoever sent them to kill or capture you, Jarl Keith, sent other warriors later to seize your flying ship."

"They must have dragged it down and pulled it aboard one of their biggest ships," I muttered. "Now we don't have a chance of overtaking Freya's captors before they reach Jotunheim."

"Aye, I fear that all is lost," Frey sighed, "Now that the Jotuns have Freya and the rune key, the Jotun king Utgar will hasten to release Loki from his prison-cave. And once Loki is free and conspiring again with the Jotuns, it will be doom for all Asgard and the Aesir."

My natural inclination was to hasten by the fastest method to Jotunheim, in an attempt to rescue Freya. But I realized that I owed my first duty to the cause of all the Aesir. It was I who had unwittingly brought the rune key that might loose Loki on them.

"Frey, tell me. Where and how far from here is the cave in which Loki is held prisoner?"
