Batman is tracking down a ten year old case with the help of some class mates. That's right; Batman is teaching a course on criminology. There are many clues indicating who has done the old crimes, such as a lock of green hair is found and who else but the Joker would be so smart as to create two-way red lenses? Joker's origin is shown for the first time in this detective comic.
