Detective Comics #1111

PAST AND PRESENT COLLIDE! Many years ago, during the early days of Batman's tenure as Gotham's Dark Knight, he trained alongside Green Arrow and Black Canary, learning the combat skills that have served them throughout their careers as crime-fighters. But there was another heroic hopeful in their ranks — a mysterious man known only as Prion — who suffered a tragic fate that still weighs upon the trio. Now, face-to-face with a young girl who goes by the same code name, they find the sins of their past coming back to haunt them. Tom Taylor and Mikel Janín bring you the penultimate chapter of this history-shaking arc!
