One of the Greatest Riddler stories
This has to be one of the best stories for the Riddler that i can think of. This shows insights into why the RIddler is what he is and why he is compelled to ask questions not only to other people, but also to himself. I guess this makes me sound like i am a fan of the man in green, but even if i was not a fan of him (which i am), I would still enjoy this adventure.
