Sherlock was still sitting at the table, had finished the call when he heard the door slam. Where had she gone? He stepped to the window and looked out. He saw her just leaving Baker Street and getting into a taxi. He leaned his forehead against the window and ran his fingers through his curls.
He could not explain why he had reacted in this way. She was here, with him, asking for his help. What was it about?, he asked himself. What had he abandoned her with now?

It must have been something important or she wouldn't have turned up at his place on Baker Street. He'd have to go and see her again later. But now he had to go to the mortuary to see Molly, who had new body parts for his experiments.

He arrived at the mortuary half an hour later.
He was about to push open the door when he heard a familiar voice and stopped. He would not listen. He would listen and perceive his surroundings with all his senses. At least that's what he used to say to John.

"I'm telling you, David told me yesterday that he loved me!"

"Really, madness! And how did you react? What did you say?" It was Molly who asked.

"I didn't say anything. Instead, I kissed him and then pretended to be asleep."

"Oh, Katie. Do you even love him?"

"No... Yeah... Maybe... I don't... I don't know, Molly. I like him a lot, but -"

"But you're not sure, are you? Is it Sherlock?"

"Molly, I don't know! I-"

Just at that moment the door swung open and Sherlock entered. Immediately the room fell silent and Katie looked embarrassed at the floor.

"I think I better go. I'm sure you two have something to talk about," Katie said now and turned around immediately.

Molly tried to stop her, but by then she was already out the door.

Sherlock stepped in, but took a quick look at her before turning to Molly.
After a short time he had disappeared again and was now following the corridor to the lift, which took him upstairs.

He stopped at the laboratory door when he heard voices again. This time it was a female and a male voice. He thought briefly of his first encounter with Dt. Reid and did not want to burst into such an intimate situation again when he suddenly heard the two of them arguing.

"How could you tell him about my past in Chicago You know very well that I still have to be careful and not everybody is allowed to know about it!"

"I only told him that you had lived there for a time. Trust me, I've known Peter forever and you can trust him." That was clearly that detective.
"Still... Just after what happened this morning. You just had no right!" she shouted.

Detective Reid was about to say something back when his phone rang.
"I'm sorry, but I have to go. Can we talk about this later?"

When Sherlock suddenly heard approaching footsteps, he quickly moved away from the door and hid in the next room. When he was sure the air was clear, he went back out and into the laboratory.

Katie stood with her back to him and angrily sorted some papers.
"Trouble in paradise?" he asked cynically.

Katie turned around in horror and then sparkled at him angrily.
"I don't see how that concerns you! And no, it was just a little difference of opinion. What are you doing here anyway? Don't you have some case to work on?"

"We were interrupted earlier. What do you need my help with now?" he asked.

"I've already spoken to Greg about it. You obviously had no time or interest in helping me," she sighed.

"Okay. Well then, that's fine. Although I can imagine that they can't help you and will turn to me anyway," he replied in an arrogant tone.

Katie twisted her eyes annoyingly.
"We will see!"

Sherlock wanted to say something, but then decided against it and disappeared from the door.
