“What's the Locomotive?” Muko whispered to Amartia.
Amartia gave her head a quick vigorous shake to indicate she had no idea. Gelio meantime was doing the screwing motion again, to show he thought Mr Hedgehog was off his rocker.
“Or maybe,” mused the professor, “it was not the locomotive but some kind of a vehicle. Yes, thinking about it … it was called 'Kaszlak' - something like that.”
“You know,” he continued, pressing his knuckle against his lips to aid concentration, “there's another amateur who's supposedly lost in a labyrinth of some kind. I've heard – that is to say, my sources tell me – that in order to reach the sculpture you have to go through a three-dimensional maze … or was it four- dimensional? Any road, he disappeared and was never seen again.”
“In fact,” said the professor, warming to his tale, “there are lots of amateurs who tried to solve the riddle hidden inside the sculpture and most of them are lost. What's possibly worse,” he added shaking his head sorrowfully, “those who aren't lost, have lost their minds.”
