Query: One of the greatest, yet saddest Batman stories ever.

While this story's fate was determined by Bat-fans, it is still a great book, featuring wondrous art by Jim Aparo, and the adventuresome writing by Jim Starlin. A shocking story which made the Batman into a different man, severing his ties with the concept of Robin, as well as his pseudo-friendship with Superman.
