Batgirl #24 pg 17

From the Bruce Wayne: Murderer arc, issue 24 finds Oracle sending Batgirl to Wayne Manor to investigate the crime scene... while the cops are there. In the process she wanders the mansion and is privy to this exchange between two GCPD detectives talking about the Wayne murders.

Love the facial expression here as Batgirl looks up at the Wayne portrait. Later in the issue, she connects what she learns here to realize Bruce Wayne and Batman are the same person.
