There was a sudden silence from the combo in the smoke. One of the trolls picked up a small rock and started to pound it gently, producing a slow, sticky rhythm that clung to the walls like smoke. And from the smoke, Ruby emerged like a galleon out of the fog with a ridiculous feather boa around her neck. It was continental drift with words. She began to sing.
The trolls stood in respectful silence. After a while Victor heard a sob. Tears were rolling down Rock's face.
"What's the song about?" he whispered. Rock leaned down.
"Is ancient folklorique troll song," he said. "Is about Amber and Jasper. They were-" he hesitated, and waved his hands about vaguely. "Friends. Good friends?"
"I think I know what you mean," said Victor. "And one day Amber takes her troll's dinner down to the cave and finds him-" Rock waved his hands in vague yet thoroughly descriptive motions "-with another lady troll. So she go home and get her club and come back and beat him to death, thump, thump, thump. 'Cos he was her troll and he done her wrong. Is very romantic song.
