Author's note: I tried to do this from Holmes' point of view, but it wasn't coming out the way I wanted. So I decided that since I hd not written anything from Mycroft now was the time for it. I only own Cassandra, everyone else belongs to Doyle. Reviews are well liked while flames are evil like Moriarty.

Mycroft Holmes was worried. There was no denying that he was. His brother had sent Cassandra with words that Baker Street had been broken into and it could only mean one thing. Professor Moriarty found out about his disguise, his cover was blown. Mycroft always believed that the mind was a man's greatest weapon, and Moriarty was prove of that. He knew what the man was capable of doing, and he also knew his brother. The destruction of the flat meant that Sherlock had no where safe to go, and the threat included that Cassandra was also discovered.

The child, Sherlock's greatest weakness. She knew the danger of what happened, but she did not fully understand the man himself and the feeling of danger one had in his presence. Though he only met the man in briefing in passing, he could tell that he was one not to quail with. Yet, the girl she wanted to help.

She wanted to find Sherlock as time passed and it was becoming late. He knew how fatal it would be and tried to discourage it. While she did as he told her and sat back down, she still had the determined look in her eye.

As the clock struck ten, Mycroft Holmes was even more worried.

"Time for you to go to bed, Cassandra." He said.

"Not until he comes back." She said stubbornly folding her arms over her chest.

"The guest room is the door on the right down the hall. There is a trunk at the foot of the bed with some clothes."

"Mycroft-

He glared at her and she sighed. "Fine."

"Staying awake until he does return will do nothing. It is for the best that you go to sleep prepared for whatever will happen tomorrow." Mycroft told her.

"What will happen?"

"At this moment, I know as much as you do. Now go off to bed."

He watched as she slowly walked into the room. It was about two in the morning when his brother finally staggered in. Mycroft walked out of his study and into the sitting room. He was silent as Sherlock sat in a chair and ran his hands through his hair in a worried gesture.

"Are you all right?" He asked.

"I'm unharmed if that is what you want to know." His younger brother said.

"Sherlock, what happened?"

"He had Patterson killed. He knew he was the one working with me. I tried to help him escape, but Moriarty knew about it. He had men waiting at the docks. I went back to the flat, hoping I could find something that might help to prove he was behind it. I found nothing, Lestrade said he looked at it and got what he needed, so I cleaned it a bit. Someone was following me."

"There was nothing you could do for Patterson, Sherlock. He knew what going against James Moriarty meant. All of us are aware of what it means to go against him."

"He still died, Mycroft." His younger brother said. "He's dead because of me."

While many people may believe his brother was heartless, he wasn't. How could he be when he was this upset over a man's death?

"He died trying to stop a mastermind. He is dead because of the crimes that man was committing." Mycroft said. "You need to think of what you will be telling Inspector Lestrade tomorrow. And keep your notes together, it will make it easier."

"No."

"Do not make it complicated for the man."

"No, you misunderstood. I'm not turning in the information I have on Moriarty."

"Sherlock-

"He is deadly, Mycroft. If I do this...there is not exact way for me to stop him. Cassandra will be danger."

"If you do nothing, there is no exact answer as to whether you will live." He said.

Sherlock did not answer. He only walked down the hall and opened the door to the guest room. Mycroft followed him and watched as the younger man fixed the blankets over the young girl, tucking them around her. Sherlock moved curls from her face and stroked her hair.

"If it means keeping her safe, I will. I failed at doing that with Bryson and when Stapleton almost took her away. I promised nothing like that would happen again." He finally said softly.

"Moriarty may even go after Cassandra, Sherlock." Mycroft whispered. "He will stop at nothing until you have lost as he did."

"Then he would not stop at just her you realize. He will go after Watson and his wife. Mycroft he may even decide to go after you."

"I know that. But, the child is everything to you. Try as you might to never admit it to anyone, she is important to you. He sees it as well. Telling Lestrade will give you some time to not only hide yourself, but to also keep her somewhere safe."

"I will not risk her."

Then don't. You know what you must do."

Mycroft Holmes was still worried when his brother silently stormed out of the room. This time it was for a different reason. He looked down at the still sleeping child and sighed softly. He was now worried for her as well. Then he remembered the determined look the girl had. Perhaps she will make him see what he must do.
