A/N: I don't own anything Batman or Chicago! related. If I did I wouldn't be on FanFic! All rights and credit where it's due to the creators and the writers!

So for some of these chapters i'll be sticking as well as I can to the Chicago! story line and for some chapters

Batman: Ladies and gentlemen! The Iceberg Lounge is proud to present Gotham's hottest dancing duo! Two Jazz babes moving as one: The Kyle Sisters!

Selina Kyle:

Come on, babe Why don't we paint the town? And all that jazz
I'm gonna rouge my knees And roll my stockings down And all that jazz
Start the car I know a whoopee spot Where the gin is cold But the piano's hot!
It's just a noisy hall Where there's a nightly brawl And all that jazz
And all that jazz
And all that jazz
Slick your hair and wear you buckle shoes And all that jazz
I hear that Father Dipp Is gonna blow the blues And all that jazz,
Hold on, hon' We're gonna bunny hug I bought some aspirin Down at United Drug
In case you shake apart And wanna brand new start To do that- jazz!
Find a flask We're playing fast and loose And all that jazz
Right up here Is where I store the juice And all that jazz
Come on, babe We're gonna brush the sky I betcha Lucky Lindy never flew so high
'Cause in the stratosphere How could he lend an ear To all that jazz?
Oh, you're gonna see your Sheba shimmy shake And all that jazz
Oh, she's gonna shimmy Till her garters break And all that jazz
Show her where to park her girdle Oh, her mother's blood'd curdle (If she'd hear her baby's queer) For all that jazz
All that jazz
Come on, babe Why don't we paint the town? And all that jazz (And all that jazz)
I'm gonna rouge my knees And roll my stockings down And all that jazz (And all that jazz)
Start the car I know a whoopee spot Where the gin is cold But the piano's hot!
It's just a noisy hall Where there's a nightly brawl And all that jazz
No, I'm no one's wife But, oh, I love my life And all that jazz (That jazz)

"C'mon babe." Amadeus Arkham said slapping Harleen's butt and leading her out the door. They'd met at the Iceberg Lounge before, Harley couldn't figure out why she was so nervous tonight. Ricky was working late and it wasn't her first time doing this. She really needed this job at Arkham and he'd promised her an interview if she did this. Her apartment, which was only a couple blocks over, seemed miles away because Amadeus stopped every couple steps to kiss her and grab her behind. When they finally got into the building he slammed her into the door of her nosy neighbor, Doris, who promptly opened her door. "Hey, Doris!" Harley gushed as he chuckled slightly and tried to kiss her. "This is.. um... My cousin!" She lied, pulling him away from her door and up the stairs to her apartment.

Amadeus was so piss drunk Harley was surprised she could even get a rise out of him, let alone get it three times. They'd been laying wrapped up in each other's arms for a while before Amadeus got up and began to get dressed. He hastily threw on his pants fiddled with the zipper. "Babe," Harley said, sitting up and staring lovingly at him. He threw on his shirt as she approached him. She buttoned his shirt for him as he put on his belt. "Y'know I don't need a real fancy office at Arkham, but a nice one wouldn't hurt, y'know?" She said low and seductive. He looked down at her, uninterested. When she finished buttoning his shirt he grabbed his tie and tried to tie it. "Actually any office'll do as long as I just get the jo-" Amadeus shoved her away and tied his own tie. "You're annoying when you speak, you know that?" He said as he grabbed his hat and his coat. "You'd never be able to keep a job at Arkham, sweetheart. You're too easy. You'd probably sleep with a patient." Harley looked up at him confused. "You said you were gonna get me a job...?" She asked as she stood up slowly. "And I'd say I was Batman to get a piece of this." He said grabbing her butt again. "You... you lied to me!" She said tearing up as he turned again to leave. "You lied to me!" She shrieked, furious. "You're a liar!" She screamed as he grabbed the handle. This can't be happening! she thought. She raced over to the chest where Ricky kept his gun. "You're a dirty liar!" She screamed one last time before she shot him.

Bang!

Not once.

Bang!

Not Twice.

Bang!

But three times.
