Batman: The Last Arkham - Storyline

Storyline

"The Last Arkham" begins with the destruction of the old Arkham Asylum at the hands of its new administrator, Jeremiah Arkham, who inherited it from his deceased uncle, Amadaeus Arkham. The asylum is revamped and fitted with numerous new security measures.

When Batman stumbles upon a series of murders, resembling the serial killer 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. This explodes when Jeremiah forces Batman to fight Amygdala and other inmates from the asylum, including the Joker, Mad Hatter, and Egghead.

Whilst this continues, Zsasz escapes through the tunnels which he had purchased and kills the builder and another inmate in order to cover his tracks. Batman defeats all the inmates and begins to wonder about Jeremiah Arkham's sanity, as Amadaeus Arkham was in fact the asylum's first inmate. Batman is put back into holding, but is freed by Nightwing, who had come to investigate. The pair split up and Nightwing encounters Zsasz in the tunnels below the building. Zsasz collapses the tunnel in on Nightwing, but is stopped by Batman who had made the agonising journey through a microwave sensor to stop him. The pair fight in the sewer and Commissioner Gordon arrives in time to arrest Zsasz.
