This issue ended on an obvious note. They're in the desert, fighting a bunch of sword-wielding assassins. Who else is the mystery villain arriving on the scene? No surprise when revealed in Detective #700. Still, I enjoyed this issue. While Batman, Robin and Nightwing are all searching for a cure to a deadly virus, Huntress is holding down the fort in Gotham keeping The Penguin and the corrupt D.A. in line.
This was a good lead-up to the big 700th issue of DC's longest-running title, as well as an exciting crossover.
