As Batman continues to fight his way through, the doctors who were working with Black Mask are attempting to flee, but are stopped by Batman, and in some ways, The Reaper . When Batman does finally catch up with Black Mask, there is a fight and Jeremiah Arkham is revealed to be Black Mask.
Batman #699 starts back at Arkham Asylum. Alyce Sinner is talking to Gordon about Blackspell being troubled. But the question comes up if he really is a serial killer, and though he’ll stand trial for the murders, something is still suspicious, especially thanks to some torture related wounds found on Blackspell. Batman, looking through Riddler’s vacated office, laments on whether or not the Riddler actually ever went straight. There had been a cash out of $10 million from Blackspell’s account, and Riddler is nowhere to be found. In the office, Batman finds an image of himself dead, with a chalk outline around him. He states that the next time he sees the Riddler, he’ll have a lot to answer for.
Batman #706 begins when Dick travels to Arkham where he interrogates Reaper, who is under heavy sedation, on top of him being nuts to begin with. Alyce Sinner allows Dick to do whatever he wants, since Reaper betrayed her by giving Batman info about Black Mask. The only usable bit he gets out of Reaper is “find the chinese butcher… you do that, you can save us all.” Elsewhere, I-Ching leaves a healing peacock to go after Sensei and save her brother. Dick continues his hunt to go find the person who was chasing Reaper: Kitrina Falcone, also known as Catgirl. He finds her training in Selina Kyle's house, and with Selina hesitantly backing him up, Kitrina decides to spill the beans, and lead Dick to the building where she found Reaper. One of the shops in the streets below is a butcher shop, where I-Ching had already busted the door in. Inside, Dick finds I-Ching’s glasses, and before he knows it, is ambushed by Sensei.

The man demands that Batman comes, and when he finally does show up he easily apprehends the man. The man says he desperately needs to see the Black Mask in Arkham, which is out of the question for Batman. The man says if he doesn’t get to see the Black Mask, then the Black Mask will kill again. Batman asks who Black Mask will kill and the man rips open his shirt to reveal an explosive device that has been surgically attached to his chest. A flashback to the Black Mask watching Hugo Strange finish up operating on the man. Turns out, he’s a financier named Conrad LeBlanc. Black Mask asks him to move around some money for him, and if he doesn’t do this or tries to have the bomb removed or disabled, it will explode. If LeBlanc plays along, he’ll get a code to deactivate the bomb, and any surgeon can then remove it easily. LeBlanc still wishes to go see Black Mask, but Batman volunteers himself. At Arkham Asylum, Batman is with Alyce Sinner and the security guard Aaron Cash watching over Dr. Arkham, who seems to have come into a position of power over the patients at the asylum. Sinner states Dr. Arkham doesn’t even remember himself to be the Black Mask, and that he is schizophrenic. Batman asks Sinner’s help in helping him try to get to Dr. Arkham, to which she agrees.

Why didn’t you stop me?!”

Arkham most likely didn’t know it was in there, and it poisoned him slowly over time. Batman gives Dr. Arkham a dose of the anti-toxin, and asks him if he remembers anything, now that the poison is out of his system. Dr. Arkham does, and begins to recount the story. As Batman is leaving, Alyce accompanies him out of the asylum. Batman says he doesn’t trust Dr. Arkham, but Alyce assures him that he’ll be watched, after all the Gotham Shield Committee elected her head of the Asylum. Angered, Batman goes to question Gordon, who says he voted against it, and was out ruled. Batman asks how it could happen since she was a murderer, Gordon responds with that there was no proof to Batman’s claims. They both agree to keep an eye on her. Back at the Asylum, Alyce tells Dr. Arkham she knows that the code he gave them was really the detination code, and Arkham laments that the man was a nasty, greedy man. As Alyce leaves, she informs him that Victor Zsasz is in the asylum, and will be placed in the cell next to him. In the hall, Alyce unlocks Zsasz’s cell, and walks away. Zsasz finds his way into Dr. Arkham’s cell and approaches him with a blade. Batman quickly rushes to the scene and asks if it is a hostage situation. Aaron tells him that it is not; Zsasz has promised to kill Arkham, given the chance. Batman bursts in to find Zsasz screaming in pain, with Arkham holding the blade. Arkham made good on Zsasz’s threat to him. Arkham went a little further, and carved his initials into Zsasz’s eyelid. Alyce puts Arkham into solitary confinement, as he laments to himself that she was testing him… Testing him to see if he was the wuss Arkham she hated, or the Black Mask man she loved. Alyce approaches Arkham, they embrace, and kiss. They look into the mirror, and instead of Arkham looking back, it is the Black Mask.
