This is when I knew I was different from other boys. The plot is similar to any of the other Hardy Boys mysteries, but the cover of this one was quite the eye opener while I was growing up. There's another pic in Sky Sabatoge
(also by Franklin W. Dixon) that involves a nearly shirtless scetch of Joe Hardy tied to a tree while two burly men torture him. I must admit, I am rather surprised no groups have ever condemned The Hardy Boys for featuring gay pornography.
Anyway, I have to get ready for work here soon. I hope everyone has a good day and I'll post more tonight when I'm awake.
