They were off like arrows sprung from the bow.

But they were too late.

It would have taken a swift horse to beat Thor and he had already gained momentum.
Like the wind he bore down on the flank of the two-year-old, swung a little to one side, and then without any apparent effort--still like a huge ball--he bounded in and upward, and the short race was done.
His huge right arm swung over the two-year-old's shoulder, and as they went down his left paw gripped the caribou's muzzle like a huge human hand.

Thor fell under, as he always planned to fall.

He did not hug his victim to death.
