Part Two
"Listen, we just want to talk to your little brother." The boy paused and thought for a second. "Tell you what, you tell me which way the scrawny git went and I'll buy you a piece of cake."
Mycroft stared at the boy while his mind was racing to conclusions.
If he agreed to the proposal, then he shall receive cake. however, his younger brother would be promptly beat up.
But if he refused, the boys, even though they were acting kind to him at this moment, would likely turn on him and he would be the one to walk home supporting a black eye.
"Well then?" The smallest of the group, a rather plain boy, asked.
Mycroft blinked. "He's travelling down Fleet Street. If you hurry, you might just catch him."
The two boys ran off down the street while the leader stayed behind.
"Thanks." He said, patting Mycroft on the back. "I'll get you that cake." Without Mycroft responding, the boy took off and ran towards his friends.
Mycroft smiled and walked the opposite way, where his brother was waiting to walk home along Main Street.
Didn't expect that, did you? This is sorta based off a thing I did, which was less than a paragraph, where Sherlock says that Mycroft sold him out for cake. Except in that, Mycroft really did.
