I have a lot of questions about Detective Comics Volume 1 #377 of July 1968.
1) Why did Robin betray Batman for the Riddler?
2) Why didn't I find any information about the front cover when I read the synopsis?
3) If Robin never put Batman in jail, then why the front cover?
4) Was there a hidden message from the front cover in the form of a Riddle?
And finally,
5) If Batman suspected Robin would betray him, how did he convert Robin back to his side?
I am just curious about this.
