One hour later, Edward found himself sitting on Sharp's desk at his campaign headquarters, waiting for the warden and his entourage to show. He idly balanced his cane on the palm of his hand while he waited. Juvenile maybe, but he could use the distraction. It also helped him focus on what exactly he'd say to Sharp. He couldn't afford to be too aggressive, considering what he'd heard from Bryant, but some force may be needed to compel Sharp to tell him the full truth of the events leading up to the murder. Edward hated to admit it, but Batman's presence may actually be welcome. The Dark Knight wouldn't let Sharp throw Edward back into Arkham simply for asking uncomfortable questions, he hoped.

The sound of the door opening broke Edward's concentration, almost causing him to drop his cane. He looked up to see Warden Sharp himself enter the office, along with a harried looking Kocen. Edward's eyes narrowed slightly when he realized that Dennis wasn't with them. Sharp himself looked irritated, though whether this was because of being called into the office at seven o'clock on a Saturday night or because of Edward's sitting on his desk, Edward wasn't certain.

"Well, here we are," Sharp huffed. "Now, Edward, you said that you found out who the murderer is?"

"No," Edward corrected, hopping off Sharp's desk. "I know who dropped off the letters. There's a slight difference."

Sharp's face reddened. "I canceled a campaign event at the office for this meeting Edward. I'm in no mood for your games."

"Fine then," Edward said. "The person who dropped the letters off is indeed an employee of yours. But they are not an employee at the asylum, unlike what we believed earlier."

"You mean what you believed," Sharp huffed.

Edward waved a hand dismissively. "Semantics, warden. To come right to the point: the person leaving the letters is Dennis, your security guard."

Edward watched as both Sharp and Kocen's expressions turn from impatient to confused. He was certain Kocen had nothing to do with this nonsense, but he wasn't sure if Sharp truly was as big an idiot as he appeared to be, or a very good actor.

"That's preposterous!" Sharp declared. "Dennis came to us very highly recommended. What evidence do you have against him?"

"More than enough," Edward bluffed. In truth, what he had was very circumstantial, but he'd caught people with less. "Firstly: whoever has been leaving the letters has the time to leave them at both Arkham and at headquarters here. Dennis's lax work schedule gives him plenty of opportunities to leave the letters as consistently as they've been dropped off."

"And just how did he get past Arkham's security?" Sharp asked. "You said yourself that whoever dropped off the letters had to have had some kind of access! Dennis was a member of my campaign staff!"

"That's true," Kocen agreed. "Campaign staff don't have access to the asylum."

A sly smile came across Edward's face. He had Sharp now. "You may not have had access to the asylum, Mr. Kocen," Edward said. He turned to address Sharp. "But campaign staff have been at the asylum before, haven't they Warden?"

Sharp's face flushed. Kocen gave him a confused look. "Quincy?"

"I've been told by a former Arkham employee that you're in the habit of sending staffers to run errands for you. Specifically, to fetch things for you at your office in the asylum. Was Dennis one of those staffers?"

"Certainly not," Sharp answered, a little too adamantly to be convincing.

"No?" Edward asked. "Then tell me: who was using your key card on the nights that the letters were dropped off at Arkham? Was it you?"

Sharp gave Edward a vindictive look. "You aren't allowed access to Arkham's security server," he growled out. "If you've been hacking into it, I'll have you locked up-"

"I'm the one who told Nigma about the key card."

The three men turned to see Batman. Edward wasn't sure when he'd come in, but he was actually happy to see him. Not that he'd let that on, of course.

"What's he doing here Edward!?" Sharp hissed at him.

"You haven't answered my question Warden," Edward repeated. "If you didn't use your key card those nights, who did?"

Sharp's shoulders slumped. "I've been swamped with campaign events the last month," Sharp admitted. "Dennis volunteered to help make sure important paperwork was dropped off at my office when I was indisposed."

Edward clicked his tongue. "Oh Warden," he said in a condescending tone. "If you didn't suspect Dennis after these letters started appearing, you ought to be ashamed of yourself. And if you did and you didn't tell me, you owe Kellerman's family an apology."

"But Dennis was in the ball room when Kellerman was killed," Kocen said. "He couldn't have been the killer."

"Dennis may not have been the person to pull the trigger, but he knows who did," Edward answered. "According to an eyewitness and my own video surveillance, Dennis spent a large portion of the time leading up to the murder on his phone with someone. It's not a coincidence the killer struck when and where they did. Dennis must have warned them about the security protocols that were put into place."

"And how the killer knew to get Kellerman," Kocen added. "Dennis must have told them what he looked like."

"That's my belief, yes." Edward said.

"And just how did Dennis know to target Dr. Kellerman?" Sharp asked Edward. Edward didn't appreciate the accusatory tone.

"Unfortunately, he got that from me," Edward admitted. "When I first examaimed the letters. That's further proof of his involvement."

"So then, Kellerman's death is your fault!" Sharp shouted at Edward. "Your precense escalated the situation!"

Edward grit his teeth. Time to drop all pretense at civility. "May I remind you Sharp, that you came to me? If you hadn't withheld information from me about Dennis, Dr. Young, and about how you conduct affairs at the Asylum, Kellerman would be alive and Dennis and his cohort would be in jail!"

"I never wanted to-" Sharp stopped mid sentence.

"Never wanted to what?" Edward asked. "Hire me? Why did you then? And why did you lie to me about the GCPD turning you away? Were you trying to justify hiring me?" Edward slowly advanced on the warden, who refused to meet his gaze. "What is this? Was this a publicity stunt that got out of control? Or were you trying to set me up?"

Sharp made no response. After a moment of silence, Batman stepped forward.

"We're wasting time here. Where's Baxter?"

"He never came into work today," Kocen said. "He's not answering his phone either."

"We'll need his address. Now."

Kocen crossed over to Sharp's desk and pulled out a file. Edward continued to glare at Sharp, who stared at his feet. For such a blustering fool, he was being quiet.

Kocen pulled out a piece of paper and gave it to Batman. "This is all we have on file on Dennis. I swear to God, I didn't know-"

Batman took the paper from him without a word and turned to leave. "Nigma?" He called out.

Edward followed him out, but not before giving Kocen a pitying look.

"If I were you, I'd look for another job."

"He knows more than he's letting on. I'd stake my intellectual superiority over it." Edward said as he followed Batman out of the office.

"I agree," Batman answered. "But I don't think he intended for Kellerman to die. I don't think he thought the situation would escalate the way it did.

"Then he's an even bigger idiot than I thought. What I don't understand is why he hired me if he hates me and had no intention of being cooperative. I shouldn't have had to find out from an ex-employee of his that he was letting campaign staff have access to the asylum."

Batman paused as he neared the Batmobile. "Maybe that was the point," he murmured. "He fed you only the basics to see if you could figure out what was going on on your own."

Edward considered this. "You mean that this whole sorry affair was a test?" Interesting reversal, given that he was the one who tested other people's intellectual capabilities. Sharp didn't seem the type...but Edward remembered what Bryant had told him.

"Strange."

Batman turned to look at him. "What?"

Edward was dying to know what the Dark Knight knew about Dr. Strange, but decided to play this card close to the chest. For now. "Never mind. So," he said, leaning on the hood of the Batmobile and giving Batman a cheeky grin. "Who gets to be Good Cop when we go fetch our accessory to murder?"

Batman narrowed his eyes. "Get off my car Nigma."

The former rogue and his adversary arrived at Dennis' apartment building at the same time. The two men entered together, walking up the flight of stairs to Dennis's apartment on the third floor. Edward letting Batman go in first. Just in case.

"When did you catch on that Dennis was the one who was leaving the letters?" Edward asked.

"After I spoke with Dr. Liew and Dr. Cassidy," Batman gruffly answered. " They mentioned that they'd seen Dennis with Sharp's key card at Arkham in the days leading up to Kellerman's murder. Also, Dr. Young's involvement in the TITAN project became known to all of the surviving staff members after the riot at Arkham. I figured that whoever was leaving the letters would have to be someone who didn't work there if they didn't already know that."

That would have been nice to know before he'd wasted hours going through the employee list, Edward thought darkly. Batman held out his arm when they reached the third floor.

"Watch out," he warned. "Baxter may be expecting us."

Edward rolled his eyes. "Please," he said, walking around Batman towards the front door. "I'm not one of those children you keep recruiting. I know how to handle a suspect."

Edward leaned his head against the door. He didn't hear anything from inside. He took a step back and cautiously rapped his cane against the door. It cracked open on its own accord.

"Unlocked?" he muttered.

Batman stepped forward, Batarang at the ready. Carefully, Edward pushed the rest of the door open and the two men entered the apartment.

"It's almost as small as mine is," Edward said as he reached for a light switch. "In addition to using them to run his errands for him, Sharp clearly doesn't pay them enough." He found the switch next to the door and flipped it, illuminating the small space.

In the center of the living room, lay Dennis Baxter, dead, with two gunshot wounds to the chest. From the look and the smell of it, he'd been dead for the better part of that day.

"Oh beautiful," Edward groaned. "Just when I thought I'd gotten to the bottom of this."

Batman walked up to the corpse and took stock. ".38 caliber," he said. "Same as the gun that killed Kellerman. The killer must have been worried that he'd talk."

Dr. Young had mentioned to Edward that Dennis had seemed agitated when she saw him on the phone the previous night. "Perhaps Dennis was as in the dark about the killer's intent as Sharp was," he offered up as an explanation. What had become of his phone, Edward wondered.

Edward walked past Batman towards what he assumed was the late security guard's bedroom. Sure enough, on the nightstand, was Dennis' cell phone. Edward picked it up and scrolled through the call history.

"Let's see: Friday night, around 8:30...Ah ha!" Dennis had made an outgoing call to a Gotham number at 8:25 that had lasted for over half an hour. That fit in with both the video surveillance and Dr. Young's account. He'd received a ten minute call from the same number early that morning. It was the last call he had received.

Pulling out his own cell phone, Edward dialed the number. After three rings, the voicemail picked up.

You have reached the voice mailbox of Patrick Horner. Please leave a message at the tone.

Edward hung up, a triumphant grin on his face. "Got you."

"Well?"

Edward turned to see Batman approach.

"According to his cell phone, our dearly departed Dennis made a half hour call the night of the murder to one Patrick Horner. More than enough time to tell him the layout of the land. Also, he received a call from the same Patrick Horner this morning, not long before he died." Edward smirked at the vigilante. He wasn't obsessed with proving his superiority over him. Really. But it felt good to get one over on him. "I think we can safely conclude that this Patrick Horner is a viable suspect."

"What's his connection to Arkham? I don't recall there being a Horner on their staff list."

Neither did Edward. "He could be a family member or a friend of one," he said. He snapped his fingers. "Here's my theory: this Patrick Horner lost someone in the Arkham riot. He's spent the last year wallowing in grief, eventually blaming the Arkham staff themselves for this loved one's death, when Sharp doesn't come clean with all the details. Now coincidentally, he happens to make the acquaintance of Dennis, our security guard. Or maybe they knew each other beforehand, it doesn't really matter. Horner realizes he has an in to Arkham through Dennis and he writes the letters, threatening Sharp to reveal the identity of the person who was responsible for the Arkham mess. Now Dennis, whether out of compassion for this Horner character, or maybe because he can't stand Sharp, not that I blame him, agrees to drop off these letters for his friend. Sharp doesn't give in though. He hires me, for reasons that are still unknown and may not be relevant. But then, I work out that a doctor was involved. Dennis was there for that conversation and tells Horner that not only am I on the case, I've figured out that a doctor was involved."

Sharp was right in a way. Edward's presence had, indirectly, escalated the situation. Sorry Kellerman. Edward shook his head and continued.

"Horner realizes that if I'm on the case, it's only a matter of time until he gets caught. He decides to target the doctors while he still can. When Dennis calls him and tells him what's going on at the fundraiser, he decides to strike. Maybe Dennis knew what he was going to do. Maybe he doesn't and tries to talk him down. Either way, Horner kills Kellerman and leaves the final letter. He calls Dennis to either get more information from him, or he figures that he's a liability and needs to take care of him. He kills Dennis and lies low until the memorial Monday morning, where either Sharp confesses who was involved, or he kills as many doctors as he can." At the end of his spiel, he turned to Batman. "Well?" he asked. "Am I brilliant, or am I brilliant?"

"Interesting theory," Batman answered. "How do you intend to prove it?"

Edward frowned. The Dark Knight always did seem to know how to take the fun out of the game.

"I have his phone number. Finding his address shouldn't be too taxing for the GCPD, let alone me."

"I'll find his address," Batman grumbled. "I need to alert Commissioner Gordon about what's happened here. You focus on figuring out Horner's connection to Arkham."

"I don't recall my reformation being license for you to start giving me orders!" Edward snapped.

"If you're right about Horner, then he'll kill anyone even tangentially linked to the Arkham break out." Batman growled out. "What do you think he'll do to you if he sees you heading his way?"

Edward saw the point, but he'd never admit it to him. "Because you care so much about my safety," he said sardonically. "Just like you cared about Jonathan's."

Batman's eyes narrowed. It was a low blow, but Edward didn't care. Batman turned towards the bedroom window and opened it. Before he left, he gave Edward one last look.

"There are people looking out for you Nigma, even if you can't bring yourself to believe it." And with that, Batman disappeared again.

Edward put his rival out of his mind as he considered his next steps. Crossing Horner against the names of the deceased Arkham staff would take time, time he didn't have. He needed a short cut.

That was why he found himself hanging Joe Bryant's door later that evening.

"What the Hell, man?" Bryant asked in exasperation. "Couldn't this have waited until morning?"

"Is there a Patrick Horner in your support group?" Edward asked in a clipped tone of voice.

"Patrick Horner?" Bryant repeated, brow creasing in thought. "Yeah. There is. Was actually."

"Was?"

"Yeah. About three weeks ago, we had Sharp speak with us regarding the memorial plans. Patrick got in his face about what happened at the Asylum and started asking what he was covering up. Sharp almost had him arrested. Patrick hasn't been to a meeting since." Bryant shook his head. "Poor guy. He lost his fiancée in the riot. It really messed him up."

"I can imagine," Edward said, even though he couldn't.

Bryant looked at him quizzically. "You think Patrick's the killer?"

Edward chuckled a bit. "I don't think so, Bryant. I know so."
