Up Against A Wall

By Icka! M. Chif

*clik*

The sound of a gun being taken off of 'safety' echoed through the small alley way.

"Hello, Kuroba-kun."

"Hello, Hakuba-kun." The thief said tightly to the teenage detective towering above him. The thief sat with his back pressed against the wall, as Hakuba pointed a small handgun at his forehead with one hand. The Kid's monocle sparkled in Hakuba's other hand. If Kaitou's smile was a bit strained, neither of them mentioned it.

"Fancy meeting you here."

"Well, these things do happen occasionally."

"That's true."

"Still, nice night tonight."

"Enjoy it while it lasts, Kuroba-kun."

"Yeah. Weather this fine is so rare this time of year. It'll probably be raining again tomorrow." 

"It will be like the sky is crying for you." The blonde detective smirked. "Unlike Aoko-chan. I believe she'll be very pleased. Think she'd go out on a date with me to celebrate?"

"I'm not sure. She's a very contradictory girl."

"Hmm... So she is. But very beautiful."

Kuroba chuckled.

"What's so funny?"

"Was just thinking that you've never seen her at her most beautiful. You'd never make it past her mop."

"What's that supposed to mean, Thief?" Hakuba's eyes narrowed.

The Kid smiled back innocently, leaning his head against the wall. "So, Why did you do this?"

"That's my line."

"Hmm... So it is."

The Detective frowned. "Why -did- you do it?"

"You're the detective. You tell me."

"That's not the correct answer."

The other boy clucked his tongue disapprovingly, shaking his head. "Now see, Hakuba-kun, this is why you will never become one of the Great Detectives. You don't understand what motivates people."

The blond boy stiffened, his eyes sparking in anger. "Meaning?"

"You wouldn't believe me if I told you." The Kid slowly eased himself up right, careful not to make any sudden moves. He finally looked Hakuba in the eye. "But I will make you a deal instead."

"I don't make deals with criminals."

The Kid smiled, leaning forward so that their noses almost seemed to touch. "If you can figure out why I do this, maybe, just maybe, I'll let you catch me."

With a flash of smoke and light, the Kid disappeared back into the night sky from where he had fallen.

"Come back here!" Hakuba shouted, firing at him. A small flag bearing the word 'Bang!' popped out of the gun barrel instead. He realised at the same time that the monocle had disappeared from his grasp as well. 

"Dammit!" He tossed the fake weapon down at the ground, feeling no satisfaction when it bounced against the wall where the Kid had been seconds before. 

He sighed and leaned against the wall, looking up at the clear patch of sky he could see from the alley, the answers to his questions falling through his fingers as illusively as the thief.

Why did he do it?

Fin.

"How come you did that?" is the translation we could find of what Hakuba says. But we're more of a 'why' then a 'how' type person, so it was changed. Fits better anway...
