Batman: The Last Arkham

When Batman stumbles upon a series of murders, resembling the serial killer Victor Zsasz's MO, Batman begins to investigate only to find Zsasz has been imprisoned in Arkham Asylum during the course of the murders. Determined to prove Zsasz guilty, Batman and Commissioner Gordon stage Batman's insanity in order to get him committed to Arkham and further investigate. However, Jeremiah Arkham is unaware of this plot and begins to break down Batman mentally and physically. Learning of Batman's incarceration through private talk with Jeremiah, Zsasz guesses Batman's insanity is obviously a ploy and begins to plant seeds of hatred towards Batman in Jeremiah's mind.
