Sherlock couldn't believe that Castiel was in London. He thought that he had disappeared from the garrison a long time ago, but obviously he was wrong. Sherlock remembered when he met Castiel, even though it was so long ago.

Sherlock (his real name was Destiel) was in a different vessel, of whose name he couldn't remember. He was a fairly new angel at the time and needed help controlling his powers. Unfortunately that was the time when he was cornered by some very powerful demons. He had tried to fight them but all he conjure up was a same fire ball. They had just laughed at him (which wasn't very nice) and then tried to kill him. Tried being the key word. Castiel had come and sent them to purgatory. From then on Castiel had decided that he would keep him safe until he had full control of his powers. Even after Sherlock had gained full control he still stayed his best friend. Then, Castiel joined the Winchester brothers, which caused him to basically leave the garrison, therefore leaving Sherlock behind. Once Sherlock had found that out, he switched vessels and started a new life.

The vessel of whom he was now occupying was Sherlock Holmes. He was a ordinary man, until Destiel came along, who lived a normal life, but there was something about him that was special. When he confronted Sherlock in a dream, he learned what Sherlock's wishes were: to be the greatest detective in all of Great Britain. Destiel promised him that he would grant that wish, if Sherlock could provide his body as a vessel. Sherlock instantly agreed, and then Destiel went into him, becoming Sherlock's grace. From then on, Sherlock Holmes became the greatest, and only consulting detective in all of Britain.

"Sir, you are at your destination." The cabby announced to Sherlock. He said thank you and paid for his ride; Sherlock had arrived at his brother's club. When he walked in he was instantly greeted by Mycroft Holmes, the famous hunter.

"Are you sure?" Sherlock asked him.

"Yes, I told you so when you first texted me." Mycroft said.

"I know. I am just confirming."

They had reached Mycroft's private office area by now and Mycroft shut the door. "This was left here for you." Mycroft said as he handed Sherlock a envelop.

Sherlock opened it and the queen piece of a chess board fell out along with a letter.

Bonjour, Sherly

It's been awhile since we've play cat and mouse and my life has been a bit boring and it appears yours has too. So I have come up with some great little games for us play. Or more like one game. Who can get to the sweet innocent angel, Molly Hooper first. You job is to basically keep her safe from me. If I am able to capture though... well let's just say that won't be very good for her. Oh, dear I've said too much already. I must stop or else I may just accidentally tell you all my plans, but that's not gonna happen.

I've made my first move. Now you make yours.

Ciao ~ JM

"He is going after Molly." Sherlock said quietly.

"Molly? He isn't going after John, who seems to be your rock to this world."

"No. I don't see why he would. He is just a normal human."

"But why Molly? She is just a simple angel!"

"There may be more to her than meets the eye. She must be hiding something. I need to find out what it is." He walked briskly out of Mycroft's office and just got outside when he heard an explosion.
