On the job of a routine delivery, Dodger finds himself in the middle of an outright mystery. A small town’s money has gone missing from their fine and fancy bank, but no one seems to know how it happened, considering the vault was locked up tighter than a miser’s fist clutching his first penny. With a little help from the professor’s weird science, it’s up to Dodger and the local town drunk to bring the culprit to justice and retrieve the town’s wealth. It’s all about of the size of things, in this latest Railroad! tale.
