When Herbie and Violet's arch-enemy Sebastian Eels turns up in Eerie-on-Sea seemingly back
from the dead it can only spell bad news. The town may welcome his entrepreneurial scheme to
resurrect Festergrimm's Waxworks a dusty and defunct old gallery of spooky characters from
Eerie legend but Herbie and Violet are suspicious of his motives. And when they learn the
legend of Ludo Festergrimm the clockmaker creator of a vast mechanical robot that wrought
havoc in the wrong hands they KNOW they're on the right track. But how can they get the
residents of Eerie-on-Sea to believe them?
