Batman / Superman #3

In "Who Are the Secret Six? Part Three," Superman takes a dangerous gamble by injecting himself with Joker toxin to infiltrate the Batman Who Laughs' inner circle, while Batman grapples with the unsettling truth that someone he trusts deeply may be compromised. Written by Joshua Williamson and brought to life with sharp, dynamic art by David Marquez—both interior and cover—this gripping chapter pushes the heroes to their limits in a story where loyalty is tested and deception wears a familiar face.
