I started reading this one because I noticed a name of one of the characters in Season 2 of the Hardy Boys on Hulu was in this story. Well, there is a whole lot more than just one character name.
Having not watched the entire series yet, I can't answer as to how well the two versions match up for all the characters mentioned, but there are a lot of "easter egg" names in the first two episodes of which at least three I have found so far from this book alone.
