Harley Quinn #24 (2014)

(W) Amanda Conner, Jimmy Palmiotti (A) Chad Hardin (CA) Amanda Conner. Harleys got an endangered friend to save, but theres just one problem: shes got to get through Arkham Asylum first! Unsurprisingly, Harleys not eager to set foot in the site of some of her darkest hours...and she definitely isnt ready to face a certain someone whos laughing at the end of a dark hallway...
