"Why have you summoned me here?" Castiel asked. He was wearing his usual suit and trench coat. He was in London, England, by the Thames River. It was about midnight and he was talking to a woman.

"I need your help." She said. She had a light voice. Not too loud, but not too soft.

"With what exactly?"

"A demon problem. His name is James Moriarty. He has been causing a lot of crimes, here in London. And they were all created for a Sherlock Holmes." She said the name so tenderly, that Castiel knew she must care for this Sherlock Holmes a lot.

"Why do you need my help? I know you are a powerful angel. Why can't you stop him?"

"He is too powerful for me. He calls himself a consulting criminal. People go to him to kill certain people. About 3 years ago he did just that. And why didn't I stop him? He is too powerful for me. When ever I went near him... his own presence drained be of my power. That's how evil he is."

"How do you expect me to help?"

"You know someone who might. Sam and Dean Winchester."

"How-" He started

"Castiel, every angel has heard of them. Please, I need their help or I won't be able to defeat him!"

"And you haven't fought him man to man?"

"Without my powers I won't be able too! He would crush me! Now stop asking me stupid questions. Will you help or not?"

Castiel thought about it, but he felt like there was something missing from the story. He couldn't quite put his finger on it though... "Fine." He finally answer.

"Thank you."

"I'll be in touch." He said before he disappeared.

"You know where to find me." She whispered before she started walking toward her flat.

BEEP BEEP BEEP

Sam Winchester slammed the alarm.

"Rise and shine ,sleepy head" His brother Dean said. He was wide awake with a cup of coffee in his hand. Sam fell back onto the bed and rubbed his face. He looked at the clock, then sat right up. "Dean! I asked you to wake me up at 6 not 8! There is a big difference!"

Dean shrugged, " You deserved a good nights sleep. Last night's demon was a tough one."

"Thanks." He got up and went to get a cup of coffee. Dean turned around to get another and jumped. "Cas! Has it ever occurred to you to appear outside the and knock!?"

"Sometimes there isn't a door to knock on."

Dean was silent.

"What do you need?" Sam asked as he walked over.

"I was summoned last night and a friend of mine asked for help. There is a demon problem. This demon is apparently very powerful, she said that when ever she got near him... her powers wouldn't work."

"If her powers wouldn't work, then how did she escape? How come sher couldn't have trapped him and then killed him?"

" The way she made it sound, was that this demon has other demons watching him. Most likely one of them would have come up behind and killed her. As for the first.. I don't exactly know."

"That's great..." Dean muttered.

"Where is it? We haven't seen anything on the news that has shown any demonic activity." Sam asked.

"London."

"Very well then. We'll take it." Sam said.

"Are you sure?" Dean asked.

"Yes."

"Very well then. London it is."

"Pack the tools that you need." Castiel said. After a few minutes they were ready to go. Castiel then took a deep breath and then touched their foreheads. When the brothers opened their eyes they were in London. He fell forward and Dean caught him.

"Whoa! Are you ok Cas?" Dean asked.

"Yes. I just haven't transported that many people this far before."

"Do you need to rest?" Sam asked.

"No, I'll be fine. I need to go See Molly anyway." Then he disappeared.

"Who's Molly?" Dean wondered aloud. Sam shrugged.

"Maybe she is the person who asked Cas for help."
