Thanks for reviewing! I'm in need of suggestions about which way to go! Any ideas then please tell me!

Batman had returned after two hours as nightfall clocked the mansion turning ever corner into a hidden land of horrors.

"She a scientist for the government, but its very hush-hush." He informed them all over the com link as he patrolled the main bedroom corridor. Carlings had gone to bed satisfied that only Wonder Woman and Batman would be in the mansion.

"I have a feeling that the government are doing something that the people won't ever know about and Marian wants it for herself." He turned the corner and signaled to Wonder Woman that everything was okay.

"So you think they have made a weapon of some kind?" She asked over the com so everyone could hear.

"Seems like it." The Lantern answered from under the window at the end of the hall.

"I just wonder what it is and how dangerous it could be?" Superman said from his up above.

"We'll just have to hope we catch her before she gets to Carlings. He seems to be first on her hit list." Batman concluded, turning back round with Wonder Woman and beginning their patrol again.

Just outside near the gate Flash and The Green Lantern walked down the gravel path in silence.

"What do you think she wants?" Flash asked as he looked to the left of the gate.

"Power? A thrill? How should I know?" he asked.

"Just wondering what her deal was." He said before turning back round and retracing his steps toward the corner of the house, nodding to the guards by the trees.

Marian finally dropped out of the tree just behind the guards and out of sight of the two heroes.

She crouched down and waited for the guards to step back slightly. Just as one did she sprang forward with a dagger and thrust it into one of their necks while she kicked out at the other. Her foot connected with his forehead and he slumped to the floor dead.

Finally she pulled the dagger free and wiped the blood off with a waist scarf. She pulled out a small mirror on a stick and pocked it out around the hedge, watching as Flash and the Lantern stopped at the end of the path.

She took a chance and rolled out from behind the hedge and up to the side of the house. Breathing lightly into her scarf she began to calculate the angle at which to jump to reach the roof.

She took a careful deep breath and leapt up, jumping onto the window ledge of the ground floor. From there she flipped upward, curling herself up for memento and threw out her arms to catch onto the top ledge. Again repeating the flip she landed safely on the edge of the roof where she rolled behind the chimney and sank into the sitting position with her back to the bricks.

She pulled out the mirror from her belt and watched as Superman and Hawk Girls walked along the edge of the roof. Carefully she crept to the other side of the chimney to stay out of sight from the two.

She sat looking out across at the far edge of the lake on the other side of the house. She sifted through her memory and laid out a mental plan of the mansion.

Skylight!

She waited till the two heroes had gone to the corner of the roof and were just turning when she ran out from her cover and slid behind another chimney, putting the sky light with in seven foot of her.

Again she waited. This time she waited till they had gone behind her fist chimney and then she ran forward, popped the glass open and jumped down into the building.

She crouched down onto the carpeted floor, presenting a smaller target. Her head snapped down to both ends of the corridor, her hands in her cloak in case of attack.

Satisfied she stood back up and walked quickly to the end of the corridor. But before she got there she heard footsteps. Thinking quickly she jumped down a connecting passage way and put her back to the wall where the footsteps were coming from so they couldn't see her.

She pressed herself further into the wall as Wonder Woman and Batman walked past, deep in conversation over something about the government. She waited till they had passed her before she stepped forward and into the wall opposite. Keeping her back to her new wall she listened as they stopped at the door of the main bedroom.

Realizing she was trapped she moved carefully along the wall away from the main corridor and further into the passageway. She came to the first door on her side of the wall and, keeping her back to the wall and her eyes on the passageway's end, she grabbed onto the handle and twisted. The door opened and she slipped into the room and closed the door.

Quickly looking around the room she found she was in the main office that adjoined the master bedroom. She glanced to the window and noticed the sensor beams that would activate if anyone opened the window.

She crossed the room and pulled out a lock pick, starting to unlock the door. However, she stopped when she heard the door she had come from open.

Wonder Woman pocked her head into the room and glanced around. She stepped in and swung the door fully open. Batman walked in behind her and then went to the window where he checked for any tampering with the window. Finding non he walked back out the room and waited for Wonder Woman to close the door.

"It just precaution Diana." He explained at her expression. "It must be done." And the two rounded the corner back into the main corridor.

Marian waited till the count of sixty before she pushed the desk chair out of her way and crawled out from under the desk. She stayed close the floor and peaked round at the door finding it closed.

She crept back over to the locked door and unlocked it with the fallen tools on the floor, silently scalding her self for not hiding them. She was actually quite surprised that Batman hadn't spotted them but she supposed the slight curl on the carpet edge had cover the tool enough to hid it from a quick sweep of the room.

The lock finally clicked and she pushed open the door, standing back up and walked into the room, closing the door with a small click.

She walked to the bed and tilted her head to the side, watching the man sleep. A smile graced her hidden lips as she pilled her long bladed sward from her back and slid it between the mans chest, cutting deep into his heart.

Carlings eyes snapped open and his mouth opened in a momentary silent scream before he collapsed back on the pillow. Her smile widened as his blank eyes stared up at the ceiling.

As she began pulling the sward free she heard a sound and saw the door fly open and a man suddenly appeared beside the bed.

"Fast exit!" she muttered, springing up.

Flash and the Lantern had gone back down the path to find the two dead guards, one with a hole in his throat and the second with a collapsed skull. Flash had instantly run off up to the main bedroom, being the fastest he figured he could get there and protect the man until the others arrived.

The Lantern instantly shot up as Flash sped off and began calling for the others to get to the room and guard the man and Flash. He himself flew up to the office window and broke through, ignoring the alarm. The office door hung open where Flash had run through a second before.

Just as he reached the door himself he heard glass break and shot through, dreading the worst.

Flash stood, dumb struck at the sight of the lifeless man, bleeding over the linen. A woman stood over him still holding the sward in his chest. She calmly pulled it free and wiped the blood off, before she ran to the window.

The alarms began screeching out as the Lantern had flown through the office window, scaring her off. In an instant she was through the window and free falling to the floor. She spread her cloak, slowing her descent slightly and rolled over as she connected with the floor.

She came up to her feet, holding her shoulder slightly and began running for the wall. She turned as she saw the flash of green from the Lantern and jumped to the side, pulling a ray gun out. She held it steady and waited for him to fire again. As he fired she fired. Her yellow beam met his green and cut through, finally reaching him and burning him. He fell unconscious to the floor.

She then flipped up into the air and pulled her sward out of its holder. Batman was running down the path with his bat-a-rang out with his hand in the air ready to throw it.

Marian turned upside down and cut the bat-a-rang in half still in his hand. He stopped dead, spun round and threw a punch as she landed behind him. She turned her sward with the point down and blocked his punch, kicking out at him. The kick connected and sent him back a few steps, which she followed through with a flipped kick to the chin, knocking him out.

She then turned to Hawk Girl who came screaming from the top of the roof. With a well-aimed throw her sward pinned Hawk Girls wing to the side of the house. Marian jumped up into the air and kicked the pinned Hawk Girl in the face, knocking her out as well.

Marian pulled the sward free as she fell to the floor and dodged the attacking Flash. She raced across the gravel path and sliced a chuck of the cement wall out before she jumped up and stepped onto the top of the wall. Putting all her weight into her balanced foot she pushed off, breaking the wall along the missing chunk, causing it to fall into the path of Flash.

He stopped in his tracks but was unable to dodge the already air born Sais. They connected with his wrists and pinned him to the floor. He pulled and twisted but found it impossible to free his hands.

Marian landed next to him but gazed at the approaching Superman and Diana. She stepped into a fighting stance and waited.

Dipping into her cloak she pulled out a ball, very much like a grenade, which she threw. Superman caught it and held it in a fist, thinking it would just explode harmlessly in his hand.

It exploded, but he soon fell to the floor, releasing the green glowing kryptonite crystals. Superman lay coughing against its affect as Wonder Woman flew over to Marian.

Marian ducked at the last second, grabbed Diana round the wrist and threw her over into the mansion. With that done she race off out of the grounds and dodged the Martian.

J'ohn didn't both going after her as he ran over to Flash, getting him up and starting him off with clearing the poison from Superman. By the time everyone was revived, Marian was long gone.

"Why didn't you go after her?" The Green Lantern asked the Martian.

"Because she would have found your weakness too." Batman answered for J'ohn as he got up, rubbing his head slightly.

"Why didn't she kill anyone?" Hawk Girl asked, rubbing at the trickle of blood from her wing.

"Because we weren't on the list...or at least near the top of the list. She seems to like an order as to how she kills." J'ohn explained. "But she'll eventually come for the sport." He added, to which everyone nodded.

Marian danced down the city street to an unheard song. She spun round in a circle and opened the apartment door, closing it with her foot. Dancing up the stairs she imagined what she would do once she go hold of the research.

"Something fun!" She mused to herself as she leapt into her room and hummed to the blank wall. "Something to play with!"

Okay disturbing slightly, but you get the point. What do you think?
