Chapter Four

The door burst open and two guards rushed in, Harleen sat up in shock, she had been fast asleep. "What's going on, has something happened?"

The officers had stopped in their tracks and were staring at the bed; the Joker appeared to still be asleep despite the chaos in the room.

"We thought he had escaped doc, a body's been found in the hospital grounds and it looked like one of his."

"Oh my god, what happened?"

"It's the nurse who attacked the Joker a couple of days ago, he's been cut to pieces, a patient found him in the grounds while they were walking."

Harleen sank back down into the chair panic rising in her throat, had he done it? Surely he couldn't have got out while she was in the room?

"As you can see officers the Joker is here, it couldn't have been him. I haven't left the room all day so it must have been someone else."

"Looks like we may have a copy-cat on our hands, unless he got one of his men to do it?"

"As you know officer there are no visitors here, this ward and this patient are off limits to everyone including other hospital staff. It must have been someone else."

"If you see anything or hear anything doc, please let us know."

"Of course, now if you'll excuse me I need to see to my patient." She stood up on legs that weren't quite as strong as they should have been. Had he somehow managed to get out without waking her?

The guards left the room and the doors closed. She looked at the Joker, god the man could sleep! She pulled back his sheet to check his dressings and gasped. His clothes were blood stained but it didn't appear to be his blood. She felt the bile rising as a wave of nausea swept over her and she gripped the side of the bed for support.

The Joker opened his eyes and smiled lazily at her "something wrong doc-tor?"

"What have you done?"

He giggled, "I went out to plaaaay, I got bored watching you sleep."

"You killed that nurse didn't you?"

He laughed "lighten up Harley, he isn't worth worrying about."

"Oh god, this can't be happening" she slid to the floor and buried her head in her hands. "Why didn't I say anything when I knew you could get out? Now that poor man is dead and it's my fault" She started to cry.

Instantly he was out of the bed and beside her, he hadn't even bothered with the pretence of the cuffs.

"Why didn't I tell Gordon the first time you had me by the throat, I could have stopped this and that nurse would still be alive."

"You tell me doc" he chuckled softly.

"I don't know, I should have done but then they would have locked you up even quicker and I couldn't……." she stopped.

"Couldn't what?"

"I couldn't stand to see you locked up." She said quietly

The Joker laughed "How touching doctor, but isn't it your job to nurse me back to health for our dear co-mission-errrr?"

She nodded unable to speak as she realised she had let everyone down, not least of all herself.

"Well my dear, you have only a few more hours of my company to enjoy so I suggest you make your mind up. You can either turn me in or I'm leaving as soon as it gets dark."

"What do you mean?"

"I mean doc-tor that you can see if your morals can save you from your current pre-dic-ament or you will have to live with the guilt of having let me walk away." He grinned at her "I have enjoyed seeing you turn from a stuck up little girl who thinks everything is black and white to this woman I see now who definitely has po-ten-tial."

She stared at him in horror "you mean that this has all been a game to you? That you have been playing with me just because you could? I have lost everything I have ever believed in because of you! Whatever happens I will lose my job and my career, I will have nothing just because you were bored!"

He laughed "But it's been such fuuuun, don't try to deny that you haven't enjoyed yourself." He leered at her, "I know you enjoyed our little shower."

She blushed, furious with herself and with him, he had played with her and she had fallen for it, or rather fallen for him. She had protected him, cared for him and he had abused her mentally and physically and she had enjoyed it!

"You're loving this aren't you?" she hissed at him.

He smiled and moved closer, his face was inches from hers, stroking her hair he whispered "you're really beautiful when you're angry"

She shivered despite herself, what was it about this man that was making her lose all rational thought. She was a doctor not some hormonal teenager with a crush. She gazed into his eyes once again finding herself lost in their depths. In spite of everything he had just told her, she still wanted him, she still couldn't bear the thought of him caged. As he kissed her she knew that she would just let him walk away. What else could she do, she loved him.

The Joker smiled as he kissed Harleen, he would be sorry to leave all this behind, she really did have potential and no one else had ever kissed him like she did. She kissed him as if her very soul depended on it and he felt himself respond.
