Author's Notes: This crossover only uses the core idea of Spyboy, it doesn't actually use any Spyboy characters. It doesn't feature realistic gun fights, instead it uses Spyboy's over the top "Gun Fu" (head shots done while doing backflips and similar antics). It doesn't feature Spyboy technology. It does features said "Gun Fu" as being equal to or better in a fight than most magic. If any of that offends you, please don't read further. The Walther PPK is used because a) it's a rather small gun, feasible to be used by a girl and b) it was James Bond's gun.

Harry Potter and the Spygirl

Chapter 1: Deadly Flashes

Standing in the office of the Headmaster, waiting for Dumbledore to return, and thinking back at that moment in the Department of Mysteries, Harry Potter still wasn't entirely sure if he should feel awed or afraid. Or both.

There had been hints, he realized. 12 year old Hermione Granger had managed to dodge a mountain troll's attacks in a cramped bathroom without getting hit at all. She had knocked out Draco Malfoy with a single punch in their third year. Pomfrey had to keep the idiot in the infirmary for a few days to heal his broken jaw. Hermione had proven to be very nimble on her feet, despite her aversion to Quidditch, and was the member of the Defense Association that was the hardest to hit with a spell. And she had organized a clandestine combat training group under the nose of a sadist inquisitor. Still, who would have known what would happen when he made her look at a box with flashing lights? Apart from her father, of course. Harry had gotten the box from him before boarding the Hogwarts Express for his fifth year.

That the Grangers had been there to say their goodbyes had been a surprise for everyone since Hermione had spent the last part of her vacation at Grimmauld Place 12, with Harry and Ron, and had gone with them and the rest of the Weasleys to King's Cross Station on September 1st. Hermione had been talking with her mother, obviously happy to see her again before going off to Hogwarts, and her father had taken Harry to the side for a more private talk.

Mister Granger had looked so serious - intimidating, really - that Harry had been about to swear to the man that he and Hermione were just friends, and that he didn't need to worry - he had heard about the talk fathers supposedly had with the boyfriends of their daughters. The man had waved his explanation off though. Instead he had handed him a small black box with a row of small colored glass bulbs set in one side and a button on top, and made him swear that he'd carry it with him at all times, and that if Hermione ever was in danger, he'd hold it in front of her face, light bulbs facing her, and push the button. It was a strange thing to promise, but Harry had been sure no one facing Mister Granger right then would have objected. He had never known dentists were so scary.

Hermione had noticed his nervousness, and had scolded her father for scaring "poor Harry", claiming he'd never hurt her. She hadn't claimed they were just friends though, a fact Harry had missed back then, but now remembered.

He glanced at her, standing on his right side, still covered in blood that was slowly drying, looking alert and tense despite the fact they were in one of the safest places in Britain, and remembered what had happened less than an hour ago.

"Now give me the prophecy, or we start using wands."

Harry and his friends, intent on saving Sirius Black, had run straight into a trap by Voldemort. They were facing a dozen of his most trusted Death Eaters, and Harry was sure the only thing that prevented the masked dark wizards from killing him and his friends right away was the prophecy orb he was holding in his hand. Voldemort had planned this trap to get that orb, and his followers would not dare to risk damaging it. But if he didn't hand over the orb as Lucius Malfoy had demanded then they would try to use his friends to force him to. Harry knew he couldn't let them harm his friends, but he saw no way out. Then he remembered the small box he had carried around with him every day since the year had started.

Even if they all died due to his foolishness, at least he'd not have broken that promise. He pulled the box out of his pocket, with one hand. "Hermione." His soft word made her look at him, and he pushed the button. Bright lights flashed in a dizzying array of colors, causing most of the death eaters and his friends to jerk and raise their wands. Hermione shivered, blinking, then Harry could see her expression change from surprise to determination and her left hand dipped into her enchanted pocket while she turned towards the assembled Death Eaters again.

Malfoy kept the other Death Eaters from attacking and drew Harry's attention away from Hermione right when she was pulling something out of her pocket. "What was that, Potter? A pitiful attempt at a diversion? Are you not curious at all about the content of the prophecy? Do you know how it shaped your li…"

Malfoy's words were cut off by a loud crack and a hole appeared in the man's forehead, right between his eyes. The wizard was just starting to fall down when another cracking noise was heard and the Death Eater next to him, still wearing his mask, jerked, blood pouring from his throat.

"Scatter!" Harry shouted to his friends, diving to the side and sending a stunner at the closest Death Eater. In an instant the stand-off had turned into a chaotic battle. Luna sidestepped a green spell and ducked behind the shelf next to her. Neville jumped back and sent a stunner at the robed wizard behind Malfoy while Ginny dropped to the ground, then rolled towards Luna. Ron blew up a shelf of prophecies, filling the room with a cacophony of voices as the prophecy orbs shattered and released their content. And Hermione… Hermione ran towards the remaining Death Eaters, the pistol in her left hand firing rapidly. She jumped over a killing curse, flipping over, shooting the caster while in the air, and landed on her feet in a crouch. Another dark wizard cast a brown curse at her, which she narrowly avoided by throwing herself to the side and rolling away. Two more shots rang out and the man who had tried to curse her was falling down, bleeding.

Harry barely avoided a body-binder while staring at his best friend ramming her shoulder into another robed enemy, dropping something in the process - a pistol magazine, his seeker-trained eyes told him. While he hit the one who had attacked him with a stunner Hermione stuck the now reloaded gun under the mask of the man she had just tackled and shot him in his throat. Blood splattered the front of her, but she didn't seem to pay it any heed. The wounded Death Eater was clawing at his neck and making a horrible gurgling sound while she whirled him around and used him as a shield to block two more curses from the man's friends. Another bullet took down one of them while a kick propelled her now dead human shield at the other wizard, causing both to fall to the ground. Hermione shot the man into the head before he could get up again even while she was dodging more spells with acrobatics Harry thought were more appropriate for a gymnastics tournament than a pitched battle. Then he was forced to focus on duelling the Death Eater he had stunned earlier - someone had ennervated him.

The next seconds felt like minutes to Harry and were spent dodging and casting, shielding and cursing. The Death Eater - Harry had no idea who it was, just that it was a man - was not that fast nor that powerful, but he had more experience in duelling than Harry, allowing him to last longer than expected. While they were duelling he heard several more shots, and caught a glimpse of at least another robed enemy falling to the ground.

Harry was just about to break his opponent's shield with a piercing hex and then follow up with a stunner when Hermione threw herself at the man from behind, startling him and causing him to drop his shield in the process. Harry could only stare, with his mouth open, while the girl snapped the man's wand and then shot him in the face twice at point blank range, straight through his mask. Both went down to the ground.

The man hadn't stopped twitching before she rolled off him and came up in a crouch, pistol raised and looking for her next victim. Harry suddenly realized that there were only two Death Eaters left, Bellatrix Lestrange and a masked man. Another shot rang out and the man went down, gripping his throat and choking on his own blood. Bellatrix had been fighting Neville, Ron, Ginny and Luna, and holding her own against the four - more than her own. She was still unhurt, but Ron was clutching a bleeding leg, though he managed to keep up a shield, and Neville was twitching, probably from the after-effects of a cruciatus. Harry remembered his own brush with that vile spell and shivered. Neville's spells were going wide but he kept casting, screaming in anger and pain, at the woman who had destroyed his family.

The dark witch had been cackling with mad joy, but Harry could see her eyes widen when she finally realized that all her fellow Death Eaters were down - dead, Harry knew, but he didn't want to think about that right then - and she was all alone. With a screech she sprinted for the door, several spells and a bullet hitting her shield, but not causing it to collapse.

Hermione ran after her and Harry followed, shouting to Luna and Ginny to take care of the other boys' wounds. A killing curse forced the two pursuers to dodge, and gave Bellatrix enough time to reach the elevator. Before the doors closed though Harry managed to break her shield with a rather overpowered piercing curse, and Hermione shot several times, the last shot stopped by the doors.

"Did you hit her?" Harry asked, panting.

"I am positive that I hit her twice. Her death is not certain though." Hermione answered in a cold, controlled voice. She kept running and Harry followed.

They found Bellatrix in the atrium, half inside, half outside the elevator, broken eyes staring at the ceiling, her wand on the floor of the elevator, in the middle of a large pool of blood. Harry stared at the sight, then jumped when Hermione shot the apparently already dead woman in the head. He gaped at his best female friend, but before he could say anything - he didn't know what he could, or should say - his scar started to hurt. Voldemort had arrived.

The Dark Lord strode into the atrium as if he owned the place, his arrogance evident in his stride. Whatever he had been about to say was left unsaid though, since Hermione started shooting as soon as she saw him. Harry wasn't sure if she hit him, but Voldemort cast a shield and stepped to the side. He moved fast, and with surprising agility, but the boy thought he might have gotten hit. Harry himself moved forward, casting spell after spell. If he and Hermione wanted to survive this then they had to keep the Dark Lord too busy reacting to focus on either of them.

A green killing curse was launched at Harry, and he barely managed to dodge behind the fountain, which was blown up when the next spell hit it. Hermione, behind a pillar to the side, threw something at the dark wizard, which blew up shortly afterwards. Harry felt the force of the blast even behind the fountain's remains, but when he leaned around the corner of the fountain to look at Voldemort the man was still standing, a protego in front of him. Hermione was reloading again, or so Harry thought, when the pillar she was taking cover behind was shattered from the next spell of their enemy. Harry heard her cry out, hurt by debris, and rage filled him.

He stood up, shouting a piercing curse at the reborn murderer. At the same time Voldemort cast another killing curse at him. As it had happened in the graveyard a year ago the two spells collided, and a golden cage sprang up around the two duelling wizards. Harry barely noticed Hermione shooting again, nor saw her bullets be stopped by the golden barrier. All his attention was on Voldemort as they fought for dominance over the brother wands. His scar hurt, bled even, his body was so tense he felt like his muscles were trying to rip his tendons off his bones, but he was not about to give in. Inch by inch he forced the glowing ball of magical energy that was trapped between the two wand tips towards Voldemort, his passion, love, and rage driving him on.

Around them more people had arrived, some wearing auror robes, some in sleep wear, like the Minister for Magic, all gaping at the sight in front of them. Hermione was holding another grenade in her hand, and had her gun ready, waiting for an opportunity to use either against Voldemort. It never came. When Dumbledore arrived, with what looked like most of his Order of the Phoenix, Voldemort snarled, flicked his wand to the side and apparated away while the golden cage collapsed and the trapped spell energies blew up in a colorful display of magic, covering his escape.

Harry fell to his knees, shaking and panting, and Hermione rushed to his side, checking him for injuries while around them everyone was shouting about the Dark Lord's return, even Fudge. When an auror spotted the corpse of Bellatrix Lestrange the noise grew even louder.

Harry noticed Dumbledore stepping up to him, and wearily looked up at him. "Headmaster… I had a vision of Voldemort torturing…" then he spotted Padfoot behind Dumbledore and relief filled him. Sirius was alive, and unhurt! He hadn't been captured and tortured by Voldemort. While he hugged the animagus, Hermione addressed Dumbledore.

"Sir, we encountered an ambush by twelve Death Eaters in the Hall of Prophecies. All were neutralized, but the last one ran and we couldn't stop her until she had reached the elevator. We suffered two wounded. Neither was in critical condition but both need medical attention." His friend spoke calmly and in a composed, almost clinical manner.

"Neutralized…?" Dumbledore asked, eyebrows rising, while Madam Bones, Head of the DMLE, was sending aurors and healers down to the Hall of Prophecies.

"Given the demonstrated capability of the enemies to recover from stunners and body binds it was necessary to use lethal means to remove them from combat." Hermione sounded like she was answering a particularly stupid question at school.

That seemed to shake the Headmaster. "You killed twelve Death Eaters?" He sounded disbelieving.

"Yes, Sir."

Dumbledore shook his head, looking older than he had just a bit ago, then glanced around. Fudge was alternatively babbling about the Dark Lord and shouting orders no one seemed to follow. Aurors were levitating bodies in Death Eater garments up to the atrium. And the three of them were the center of attention. He glanced at the prophecy orb Harry was still holding. "Is that what he wanted?" the old wizard asked in a low voice. Harry nodded. Dumbledore sighed, then presented a sock to Harry. "Take this portkey. It'll transport you to my office. I'll join you there as soon as I have settled things here." Before Harry could take the sock Hermione had gripped his arm and Padfoot had wrapped himself around his legs.

"I'll go with him. I'll not leave him alone." Her tone made it clear she'd not accept anything else. Padfoot barked, somehow managing to convene the same meaning. The headmaster seemed to accept that, nodding after a brief pause. Seconds later the two teenagers and the dog were whisked away to Hogwarts.

And there the three of them still were. Sirius had transformed back as soon as they had arrived - Harry flat on his stomach, the other two landing on their feet - and hugged Harry so hard he had trouble to breathe. Then he had scolded him for taking such a risk, then praised him for standing up to Voldemort. And then he had hugged him again, and restarted the sequence. Harry hadn't managed more than telling his godfather how much he cared for him, and that he had seen no other choice. Hermione had been standing at their side, keeping an eye on both the windows and the door. Standing guard, Harry realized. With her clothes and face splattered with blood - pure blood, a silly part of his brain insisted - her cold eyes and her gun and wand in hand she was a scary sight.

Harry didn't know what to make of his best friend who had suddenly turned into a killing machine straight out of an action movie. And so he kept talking to Sirius, putting together the events of the evening from the Order's side. They were interrupted by Hermione when Sirius mentioned how the Order had been notified by Dumbledore and immediately had traveled to the Ministry. "Professor Snape was aware of our departure for London hours before you arrived. Someone must have delayed relaying that information to the rest of the Order."

That set the two wizards thinking, but before they could form a good theory Dumbledore arrived in his office. He looked worn and older than any of the three had ever seen him. He sat down behind his desk and nodded at the phoenix greeting him with a thrill.

"It's good to be back, despite the circumstances." the Headmaster stated, more to himself than to the three people waiting. Finally looking at them over the rim of his glasses, he continued "I have been reinstated as the Headmaster of the school, and I expect to return to the office of Chief Warlock as well within the next few days." After a short pause, he sighed. "I am sorry to say that all Death Eaters at the Ministry were dead. I have failed you, allowing you to be forced to take lives in defense of yourself."

Harry didn't know what to think or feel about that. He hadn't killed anyone directly, but he certainly had helped, even after knowing what Hermione would do. With the excitement of the fighting wearing off, he felt numb. Then he remembered Hermione - she had to feel even worse. At least he hoped she did. Glancing at her sent a chill down his spine. Hermione didn't show any emotion other than a cold smile, as if she was proud of her deed.

"If the information Professor Snape had would have reached the Order of the Phoenix in time, you could have stopped the ambush before we even reached the ministry. He knew of our plans when we rode off on the thestrals and it took us hours to reach London. This indicates either a failure in your organisation, or deliberate sabotage." Hermione stated.

"Professor Snape has my full trust." Dumbledore answered, but even Harry could see he seemed a bit disturbed by the implications. Or maybe he was still shocked by the fact that twelve Death Eaters had been killed by six teenagers. Or rather, one teenager.

"Miss Granger, I heard you were responsible for the death of a dozen people, and you used a muggle weapon."

"Correct, Sir. A Walther PPK."

"You showed a quite remarkable proficiency with that weapon. Almost unheard of in a girl your age, much less in a witch who has spent the last 5 years at Hogwarts." Harry suddenly noticed that Dumbledore had his wand in hand, and seemed quite tense.

"Correct Sir. While I am not allowed to go into details I can tell you that my training started at a very young age."

Dumbledore looked at his phoenix, who thrilled. Harry felt his spirit lift. Hermione showed no reaction, which seemed to reassure the Headmaster somewhat.

"You seem a very different person than the Miss Granger I know." After a glance at Harry, Dumbledore added "Or the one we know."

"Correct Sir. A side effect of my training to function better in combat situation."

Hermione met Dumbledore's eyes, and he gasped, then looked away after several seconds.

"I see. Remarkable. And all without magic." Dumbledore sounded sad rather than impressed, at least to Harry. "You've taken it upon you to protect your friend."

"Correct, Sir. Against any threat." Hermione bared her teeth in what could be called a smile if one was blind and very generous, in Harry's opinion. A short pause followed, during which Hermione and the Headmaster stared into each other's eyes again.

"Can we now talk about this prophecy Harry and his friends almost died for? We guarded it for a year, and Voldemort himself tried to get it, going to great pains to have Harry take it, so I think it's time to find out what it states - or is that, reveal what it states, Albus?" Sirius' voice had an undercurrent of anger. Harry suddenly remembered the initials of the recipient of the prophecy. They matched the Headmaster's...

"That would be a sound course of action, Sir. Lack of proper intelligence has already caused a very dangerous situation today. Not sharing the information would be extremely unwise." Harry wasn't sure, but he had the impression Hermione had just threatened the Headmaster. He wasn't sure with what though.

Sighing, the old wizard agreed and cast a really impressive number of privacy and detection spells. That Hermione didn't seem to pay much attention to the spells worried Harry even more than her cold-blooded killing. Then the prophecy was revealed, and Harry forgot about his concerns for his friends, reeling from the shocking news he had just gotten.
