Heidi was playing the violin as they welcomed Mrs Hudson back to baker street. John helped her to her seat and then looked at the girl on the instrument.
Sherlock walked in and sat down at the desk. Instantly getting out his laptop.
"By the way. Happy birthday" He said to Heidi. She made a screeching sound with the violin then stopped playing.
"How did you know about my birthday?" She aksed.
"I found your mothers facebook page. She wished you a happy birthday on it."
"Why do you have my-"
"She is a suspect and I have been messaging her." Heidi rushed over to the laptop. He had been talking to her. Interrogating her over messenger. Heidi teared up.
"Do you want to see her?" Sherlock asked and Heidi nodded. She wrapped her arms around Sherlock and cried.
"Oh God yes!" She said.
"Well isn't this a happy day" John said, "We have Mrs Hudson back and Heidi is getting to see her mother."
"Not happy." Sherlock said. "Mrs Jones is a suspect. She might have been the one who attacked Mrs Hudson. Given what she has said in messenger, its highly likely. I won't know until Heidi and I run the experiment."
Heidi's face dropped at mention of what Sherlock was planning. She left the room instantly.
"I hope you're not planning on getting yourself into trouble, mr" Mrs Hudson spoke. He looked at her with a face which said 'obviously'. She sighed and said "Sherlock..."
Heidi started to pack her bags. She couldn't stay if Sherlock was actually going to go through with that plan. She would not see another person she cares about get hurt. She just couldn't.
She dragged her case out and John stopped her.
"He's not going to do it. Mrs Hudson is giving him a scolding. You can go unpack" He said.
"He will do it. He's stubborn." Replied Heidi.
