LotR -- Book 2 - Chapter 04 - A Journey in the Dark

Davem, I like the point you have made about the wolves. Here is a little more...

"It is as I feared" said Gandalf "These were no ordinary wolves hunting for food in the wilderness. Let us eat quickly and go."

You can tell Gandalf feels unsure, or uneasy, about not finding any trace of the wolves, or finding none of the dead bodies. They definately seem to be from another world/dimension.
