Batman Vol.1 #668
12 years ago, the original Knight tried to attack the owner of the Club of Heroes, John Mayhew, but was instead confronted by the Legionary, who defended Mayhew.
In the present day, the heroes examine Legionary's lifeless body and begin to analyze the crime scene. Batman suggests the heroes split into groups of three, but there is much tension and distrust between the heroes. Wingman is skeptical about The Knight, as he had the motive after apparently witnessing an altercation between Legionary and his father (the original Knight) at the Club's final meeting. Gaucho defends Cyril, as he would rather have him at his side then Wingman.
Batman believes the killer to be a criminal named Charlie Caligula - the Legionary's worst enemy. He notices chicken grease smeared on one of the video monitors where Legionary died, deducing that it is the room where the killer recorded his message. The groups reconvene and find a disoriented Knight, who claims he was attacked and forced to swallow an object. That object turns out to be a bomb, to which he must throw up. The heroes remark that this gruesome death is also the way that Knight's father was murdered by his arch-nemesis Spring Heeled Jack.
