Okay so this is the first fanfic I've put up anywhere, not sure if anyones going to even read it never mind like it but hey, might as well put it out there anyway.

So I'd really appreciate feedback so please rate and review =^_^=

(edited, I realised after a while I had given Sarah the same surname as Catwoman, they are not related, it was unintentional so I've gone back and changed it now :D )

Chapter 1 - First Encounter

The screen in the batcave was covered in open files. The Dynamic Duo had been looking into a large number of robberies that had been happening in Gotham over the last month.

"It's gotta be the same perp" said Robin, punching one gloved fist into his other palm, "They're all too clean, no-one sees them come or go and the only thing different in the morning is that the stuffs gone. No way two people are that good."

"That's the problem," replied Batman "They barely leave a trace, even I had a hard time seeing how they did it."

"Had? So you did find something?" Robin pouted, "Why do you never tell me stuff"

"It's not much yet, but the glass on top of the cabinets is slightly melted at the joints, they most likely cut their way in and then reseal the cabinet afterwards. But that doesn't help know who they are or where they are going to hit next."

Alfred came down the stairs from Wayne manor. "Sorry to interrupt Master Bruce but if Master Dick doesn't leave soon he will be late for school."

"Aww man!" Said Dick Grayson as he took of the black mask covering his eyes "I thought I might get away with it this time" He hurried off to his room to get changed out of his red and green crime fighting outfit.

"If you will pardon my input Master Bruce" said the butler "but could this not be Catwoman's work, she is a cat burglar after all."

"Maybe Alfred" said Bruce Wayne as he pulled of his signature black cowl "but it doesn't seem like her sort of job, they're not cat-related at all and she likes being chased. Whoever this is doesn't want to be seen."

- At Dick's school, later that day -

The bell rang out through the halls as students piled out into the hallways, heading out now that the school day was finally over. Dick gathered up his bag, vaulted over his desk and dashed for the door, eager to get back to the batcave. He then managed to smash right into someone who was coming in and knock both of them to the floor.

"Ow," he said rubbing his head where it had hit into the teachers desk "Who…Oh gosh sorry Sarah!" Realizing it was his girlfriend he had knocked over Dick scrambled to his feet and helped her up. Sarah and Dick had been going out for about a month, they got together at a school disco and both figured it had been such a great night that they'd give it a shot.

"Oh, it's all right, I was just hoping to catch you before I went to gymnastics practice." Sarah Kacy was on the gymnastics squad and had the figure to go with it, she was just shorter than Dick, with a willowy frame and long brown hair that was so dark it was almost black. Her eyes were a deep green and they sparkled mischievously as she looked at her boyfriend. "I was wanting to run into you but this was a bit literal. You running off home again?"

"Yeah" said Dick, running his hand guiltily through his hair, "I promised I'd be back early to help with some stuff."

Sarah sighed at him, "You always seem to be busy with something, you'd better make time for me sometime Dick, or I might think you don't care" She started looking very annoyed at him, but Dick knew when she was teasing him. He swooped closer and gave her a peck on the cheek, distracting her as he twisted round her to get to the door.

"See you later Sarah" he joked as he disappeared down the corridor. Sarahs scowl turned into the exasperated look Dick so easily brought out. She couldn't even pretend to be mad at him but he seemed so hard to pin down at times. She glanced at her watch before hurrying off to gymnastics.

- Gotham Museum, that night –

"Why are we here exactly?" Robin asked Batman as they hid themselves among the roofbeams of Gotham Museum. From their position the two crimefighters had a good view of the entire main hall and could easily tell if there was someone there if the lights were on. However being closed the museum had turned of all the power except the security system that was supposed to keep anyone out. Batman and Robin had snuck in before the museum closed and had been hiding since and they both knew that the mysterious thief could easily do the same, if they were coming at all.

"Because," explained Batman "There was a cyberspike into thier system earlier today, someone hacked in and got a full diagnostic of the building. It was from a public access computer so we can't trace who it was but it's a fair guess that they will be here tonight." The two fell silent as the security guard passed through the hall for a final check. His torch beam passed over glass cases and displays full of fabulous jewels and artifacts for the new display of Egyptian relics. In the corner stood a row of boxes that hadn't been unpacked yet covered with a large sheet. The guard left, locking the door behind him and activating the overnight security. Batman drew out a thermal scanner to help keep an eye on the hall, although there was still just enough to see by it would be much easier to find anyone by their heat signature than by eye alone.

Half an hour later there was still nothing to see by man or machine. Just as Robin was about to suggest leaving a red flash suddenly appeared on the scanner in Batman's hand. Looking down to the corresponding area of the hall the pair saw the sheet covering the boxes lift away, the only sound heard a metallic rustling as something was stuffed back into an open box by a dark figure. Robin made to jump down and confront them but Batman caught his arm. "Wait, I want to see what they do." He said in a quiet but commanding tone. It was too dark to make out details but the duo were able to follow the thief's progress as they swiftly made their way to a small cabinet at the back of the room.

As the figure approached the cabinet they clenched their hand into a fist, in response four shard blades slid out of the elbow high long gloves and settled against the leather coated fingers. In the other hand was a small light, allowing a better view of what to do. Very carefully the thief ran a blade along the side of the cabinet where two panes of glass joined, then along the top as well. It was then a simple matter of levering the glass away and reaching in to take the golden amulet from inside. Before replacing the pane the thief took a small bottle from the belt slung round their waist and ran the chemical inside over the exposed edges, heating them just enough to melt the glass slightly before pressing them back together just as they had been.

Above Batman nodded and he and Robin dropped down behind the intruder. Despite their almost silent landing the thief turned almost instantly, directing the small torch directly into their eyes, blinding the pair momentarily. Taking this opportunity the figure dashed towards the door, sweeping dust off the nearest case into Batman's eyes, delaying him furthur, but Robin got there in time, still blinking the flash out of his eyes. The black-clad figure swirled round, catching Robin a kick to his side, knocking him off balance. As Robin rolled back up again he saw the thief snatch his zipwire from where it had fallen on the floor on his way down from the ceiling. Batman lunged just as the thief activated the winch and went rocketing upwards. Wasting no time Batman fired his own wire and followed suit. But then the figure did something unexpected, halfway up they swung their body round and managed to land feet first in an air vent hidden in the shadows of a pillar mid-way up the wall. There was no way Batman would be able to follow, clearly the burgler was smaller and more flexible than had been expected. Robin attempted to follow but Batman called him back. "You'll never find them, those ducts will be like a maze, whoever they are they will have examined those plans and worked out the best escape route. Its most likely that is how they got out of all the other crime scenes without passing any cameras or alarms." The pair quickly headed outside but could see no sign of the thief and the broken grill on the roof was the only evidence to show where they had left from. "Did you get a good look Robin, I still had dust in my eyes."

"No, it was too dark. But from what I could see they seemed to have a, well a tail."

- Elsewhere –

Once safely away from Gotham Museum the thief stopped to rest on top of a building. The zipwire contraption that they had taken from Robin was definitely going to be useful. It had already allowed a quick escape by rooftop. The thief moved on until reaching the safety of their home. Once inside the black-clad figure removed the costume that they wore just in case they did have encounters like tonight. Finally they reached up and took of the black mask. A strand of incredibly dark brown hair fell across a glittering green eye as Sarah Kacy removed her mask and stared at the Egyptian ankh she held clasped in her hand.
