Synopsis:
Batman begins a lecture tour around Gotham City to speak about detecting clues left at crime scenes. He belittles the Joker for intentionally leaving clues that always lead to the villain’s downfall.

Joker hears of Batman’s insults and begins a new crime wave. He once again taunts Batman with daily clues to his daily crimes. Batman is initially unable to thwart his adversary, but eventually he deciphers an important clue. The clue allows him to set a trap for the Joker and end the crime spree.
