The usual suspects
The lineup was a joke. Everyone knew it. Who in their right mind put seven professionals in the same room like this by accident? No one, that's who. Keyser smiled to himself. This would be fun. The "witness" did as he was told, of course. Each and everyone of them had to take a step forward, read a line from a note and retreat to the line afterwards. Keyser, being the first, did as he was told by the officer. The Joker was next.
Yes, Keyser would enjoy playing these guys. Very much. With reputations larger than most moviestars. Reputations that had a habit of sticking around, long after they were (often doubtfully) deserved.
