The words tumbled out of her in response. "I know! I know where it is! And she's been kept asleep by a woman who says she is her mother, but no mother would be so cruel, would she? She makes her drink something to keep her asleep, but I have some herbs to make her wake up, if only I could get to her!"
She spoke so quickly that Will could only shrug and spread his hands. It took the daemons a minute or more of talking before the understanding came into Will's mind.

"Iorek," he called, and the bear lumbered along the bed of the stream, licking his chops, for he had just swallowed a fish. "Iorek," Will said, "I think this girl is saying she knows where Lyra is. What I'll do is go with her to have a look, while you stay here and watch."

Iorek Byrnison said nothing, but stood foursquare in the stream as Will concealed his rucksack behind a rock and buckled on the knife before clambering down through the rainbows with Ama. Will had to brush his eyes frequently and peer through the dazzle to see where it was safe to put his feet, and the mist that filled the air was icy. No wonder Iorek was enjoying the water; Will could only imagine how much he had suffered from the heat of the journey.
