The official synopsis for “Batman: The Long Halloween” reads; “Christmas. St. Patrick’s Day. Easter. As the calendar’s days stack up, so do the bodies littered in the streets of Gotham City. A murderer is loose, killing only on holidays. The only man that can stop this fiend? The Dark Knight. In a mystery taking place during Batman’s early days of crime fighting, Batman: The Long Halloween is one of the greatest Dark Knight stories ever told. Working with District Attorney Harvey Dent and Lieutenant James Gordon, Batman races against the calendar as he tries to discover who Holiday is before he claims his next victim each month. A mystery that has the reader continually guessing the identity of the killer, this story also ties into the events that transform Harvey Dent into Batman’s deadly enemy, Two-Face.”
Fans will finally be able to witness one of the greatest stories of the Dark Knight in the animated format this summer.
