The river crashed noisily behind them as red and blue police lights flashed brightly against the park trees. Rory stood off at the side with Alice and Amy as the Doctor, Eddie, and the rest of the special units from Strados showed off their 'colorful credentials' to the head officer. The head officer was a lot taller than the Doctor and he was a lot more muscular than the Time Lord. His gold colored badge read in Japanese 'Sergeant Urook'.

"Honestly Sir," Eddie said, he had a hand on his hip right above his perception filter incase this went bad "we're special unit officers. My team travels all over the world handling situations like this. We kindly ask you to let us take a look."

Urook narrowed his black eyes at Eddie, who only stared back with the same level of iciness. "Why do you speak with an American accent while that one speaks with a British?" He pointed to the Doctor and then to Alice. "And that one with a Scottish? Shall I go on?"

Eddie opened his mouth to say something but then the Doctor broke in, all charm and smile. "Sorry for the rudeness of my cohort, we're jet lagged. Anyway, we hire people from all over the globe. I was from Scotland Yard, Amy and Alice were from a police force in Scotland, so on and so on. Urook, I kindly ask you to let us examine this body. We've seen murders like this and we want to help these people the best we can." He pointed to panicked people and the children who had found the body. His voice now had an edge as he said coldly "Let us take a look."

The Sergeant smiled, black eyes suddenly containing an interested glint. He chuckled "You're quite young to be a forensic expert. What's your name?"

"I'm John Smith but everybody calls me the Doctor." He said, Amy blinked, she saw the lies easily rolling off of his silver tongue. "So I ask again...may we pass?"

"Fine." Urook growled as he stepped aside, allowing passage. As the team headed towards the body and the message, The Doctor noticed a child standing off to the side, eyes narrowed at the crime scene but something told him it wasn't in horror. Urook glanced at the child and yelled "Just don't mess up my crime scene!"

Amy glanced back at the man and just noticed the way Urook was watching the Doctor, exactly like a predator would to prey. Alice took out her camera and began to take pictures of the body. It was a man no older than thirty with already greying hair, he was lying on the sidewalk, body half-concealed by the bush and staining the leaves a shade of scarlet. She picked through the branches, careful not to tear the flayed skin from the corpse. The Doctor blinked and glanced away towards the small path that lead towards the river.

"Something wrong Doc?" Alice said as she saw him freeze.

The Doctor blinked and finally said "Look, the undergrowth all around you isn't even touched but the undergrowth behind you is torn up as if there had been a path."

Eddie straightened himself up as the Doctor jumped over the bush that concealed the entrance to the torn undergrowth. He sniffed the air and stuck out his tongue in disgust. "Ugh, too fishy. Not Saturnyn though, too salty for that. Oh. Oh." He clapped his hands together as she walked a few feet along the torn undergrowth. "Oh finally, I've been dying to see this species again. Edestus! Like the prehistoric shark or something. Best hunters ever created, psychic, super-strong and fast, shapeshifting, and males have the ability to control electricity."

"They sound nice." Rory groaned. "I remember the fish people in Venice. That was a terrible day."

Eddie smirked, as he took a cotton swab and easily dabbed up a few scattered droplets. The number of people beyond the yellow tape began to swell to an uncomfortable mass, Amy cringed at all of the curses at the police. Eddie jumped up just as the Doctor said "I'm going to check this way, this man's been dead for over twenty hours. The murderer is long gone by now."

Alice nodded and went back to her work, Amy and Rory were trying to find something to do that made them fit the part. Alice never glanced at them as she said "You two can go ask anyone if they saw anyone. We need help pinpointing the Edestus people if they're still here. They could be anyone."

"How does that help?!" Amy said flatly. "How can you be calm when one of your friends could be a sociopathic murderer?"

Eddie glanced up "It's going to be okay Amy, if our signal goes down the rest of the fleet will come. It's a protection order."

Amy nodded and then Rory pulled her away from the crime scene as Eddie looked back at Alice. He blinked and said "Should we tell them?"

"No!" Alice breathed in horror. "Are you crazy? We need them to trust us."

While this transpired the Doctor skipped along the path, glancing at everything for any sign of movement for the Edestus. Before he knew what had happened he was at the edge of the river. The Time Lord glanced around, trying to find any sign of the murderer coming in this direction. Sadly there was none. The Doctor glanced knelt down next to the water and dipped his hand into the river, he brought his fingers to his mouth and tasted a few droplets.

He cringed and spat "Ugh, that's disgusting. Way too salty for this far inland!"

"I don't mind it." Said a small voice from the shadows. The Doctor turned around just in time to see a small girl, the same child from the crime scene earlier. "A lot of varying fish species. Great to eat!"

The Doctor narrowed his eyes and knelt down to her height. "I saw you from the crime scene earlier, you were much calmer than the rest of the children. Weren't you the one to find the body?"

She nodded and glanced down towards the river. "Yes, I found the man. Just another poor and unfortunate murder victim. They always turn up this close to the river, nothing shocking...happened to my mother a few weeks back."

"Terrible." The Doctor said with a shake of his head. "Did you happen to see anything?"

"No, but they seem very interested in you." The girl said with a smile, the Time Lord cocked his head to the side but then the Doctor saw her eyes turn yellow. He jumped back as she glanced down at herself "Oh, I do get into character don't I? I mean we're into you of course, the final Time Lord of Gallifrey, the final loomed. I've been dying to taste your blood Time Lord."

The Doctor stretched himself to his full height and he towered over the girl and growled "You killed him didn't you?"

"Of course." The child said as she stepped back, a childish smile on her face. "I do love killing the filth that destroyed my home in the future."

"The final people of Edestus." The Doctor said, he saw the cold enter her vision as he said the planet that had been lost so long ago. "I've been waiting for you to turn up, getting greedy with Time Lord essence aren't you? You know the laws, you cannot feast on the last of a species."

He smirked and the girl narrowed her eyes, she hissed. "I do not care for the laws of your 'higher class'. I am one of the last species of Edestus, history will remember me! I am Strall!"

"You're not the type of selfless person are you?" The Doctor snapped and Strall smiled, fangs showing and in response the Time Lord backed away. "Apparently not then."

He didn't have time to react before she lunged, changing in mid action. She stood tall, fallen to all fours despite the humanoid look. Silver scales had replaced the skin across as her clothes tore away, a long fish-like tail broke free and lashed through the air. The Doctor blinked as Strall smirked through her jaws. He glanced down at her long and clawed hands, the edges of the webbing that interlaced her fingers had a razor-sharp edge that would be used for cutting into him.

"Amy!" The Doctor screamed in terror but before he could scream out again, a large hand pinned him to the cement, crushing him against the path.

"How touching." Strall hissed, her snake-like tongue flicked from her long and pointed teeth across the Doctor's face. "The Time Lord is calling to pitiful humans to save him. Pathetic, how could they ever help you?"

"Humanity won't give up!" The Doctor spat back bitterly, Strall gave an amused hiss as the Time Lord continued on. "They'll destroy Daleks, they're braver than you in ways you have yet to see!"

"And why do they leave you?" Strall chuckled, causing the Doctor freeze, he cursed himself silently. Psychic. "Rose and Martha too...oh yes, and blondes aren't the only forgetful ones. Gingers can forget a person quite well," Strall applied more pressure to the Doctor's chest, causing him to gasp in pain as her claws began to tear into his skin "with a little help."

Suddenly Amy's voice cut through the air as she called "Doctor?"

Strall smirked through her teeth as she licked the Doctor's blood from her claws. Her eyes rolled back into her head with pleasure, she sighed and glanced down at the Doctor with distaste "How I wish to flay you here and now but it would be a waste of perfectly good blood."

The Doctor saw her shudder as she jumped away, she returned to two legs and his hearts plummeted when he saw who she was changing into. Strall grinned, her olive eyes cold as she laughed in a perfect replica of his own voice. "Hello, I'm the Doctor!"

The Time Lord's eyes widened but then something crashed into the back of his head and Strall smirked innocently, green eyes glinting as she stepped back into the forest, completely in the act of being the Time Lord. The Doctor blinked, eyes growing heavy as he fell back into the water, not even away of the claws that grabbed him as he did.
