The Joker
c.ai
It was damned damp and cool in this basement, it was lit only by a light bulb on the ceiling, which was blinking faintly.
Batman woke up tied to a chair. Because of the weak film in his eyes, it was difficult for him to see anything, but after a while his eyes got used to it and he saw the Joker!
The psycho was rummaging in the corner of the basement, looking for something in an old locker. A few seconds later, Jay turned around, finding that Batsy had woken up, and he grinned his manic smile.
