Naturally, the plot involves The Riddler setting up a test for Batgirl which involves murder and mayhem if she fails to answer his questions. The twist Tim Seeley sets up for why he is doing this is rather brilliant and I shan't say another word about it. Suffice it to say it takes a lot to impress me when it comes to The Riddler and this issue did not disappoint. While the endgame is obvious the execution is masterful.
Better than the story, though, is the art. This is the second special I've seen Minkyu Jung work on (the last one being Titans Annual #1) and the second time I wished he was working regularly on a series I read. Jung's grasp of composition and framing is fantastic and the action of the story flows smoothly throughout. Would that we could see Jung paired with Jose Marzan Jr. on Batgirl, as they prove to have a real flair for working with the character and each other here. The colors of Jordie Bellaire are sweet icing on a very rich cake and Dave Sharpe's letter-work is as astounding as ever.
The Final Analysis: 10 out of 10. A one-shot special that lives up to its name.
