"Thor," said Lynette, and now, though her voice, as before, was low and gentle, there was the note of command in it, "lie down!"

There was an experiment ... and it failed. Thor was on four feet in a flash; his growl was unmistakable now; the snarling note came back into it threateningly. She thought that he was going to fly at her throat....

Yet already was the lesser intelligence, though coupled with the greater physical power, confused.

Lynette moved slowly; she put her hands up above her head and stretched out her arms and yawned; Thor growled, but there was little threat in the growl; just suspicion.
