Welcome to the busy, industrial port city of Steamkettle Bay, the second-largest city in all of Industralia. It's filled with manufacturing factories, airship docks, inventors, artists, and lots and lots of streetwise, clever kids. It's a warm Saturday in the summer of 1872, and somewhere in Steamkettle Bay, bad things are happening. Can Paisley Pockets and Christopher Cogan stop a crime in progress? They may be just a couple of kids, but where there's a will and, some smarts, there just might be a way.
