"KnightsEnd, Part 4 of 10: Devils" continued from Detective Comics #676 and continues in Robin (Vol 2) #8.
*Batman continues on the trail of the gun-runners, while Bruce Wayne faces the seventh and most skilful of the dead sensei's disciples, still unaware of exactly why they are pursuing him. Batman defeats an armored man working for the gun-runners, and, after a long fight, Bruce Wayne gets the advantage over his opponent. Knowing that Shiva will not be satisfied with anything less, he then delivers the killing Leopard Blow, unaware that he is being watched by Robin and Nightwing. *Source: DCUGuide.com
