storyline (occurring simultaneously with Batman 450) 
Batman and Gordon discovered a murder victim that appeared to be a part of some sort of ritual on the night of the Penguin's bird attacks. Batman found another victim in the same fashion and also heard of a strange "red-hooded gunman" loose in Gotham City. At the plane crash site (see Detective 615), Batman found an archaeologist who spoke of "dragon lines." Both ritual deaths had occurred on one of these lines. They were too late at the next location, and they thought the next would be at Wayne Manor. A deer was found dead there. Next on the line was the archeologist's home. Batman stopped the being by separating it from it's magical scepter. It fell into the harbor. Batman realized Joker was on the loose (Red-Hood).
