Your P.O.V.

It was the 21st of April. It was unbelievably warm for April so I had my summer dress on. Stretching the last bits of sleep off my body I walked to the kitchen, opening a window on the way, turned on the radio and grabbed a (favourite fruit) from the kitchen counter. Smiling happily, I danced to the window. The song on the radio was one of the newest hits, and I sang a duet with the female vocalist, familiar with the lyrics. The view from the window was picturesque. Oh, London. It was so beautiful with its red buses, small shops and pubs. Its people and the scenery of the late morning sun. And I of all people had the chance to live here. I took a bite from the (fruit).

3rd person P.O.V.

Would you like to come over for tea? JW

John sighed as he pressed the 'send' button. He was nervous even thoug it wasn't the first time he messaged a woman. A friend would be a better word anyways. He leaned back in the usual armchair, telling himself to calm down. But it made no difference. He was too tense.

Two minutes passed and his phone rang a short alarm sound. Overly excited, John grabbed the phone and checked who it was. (Y/N). She said yes. He felt himself ease up in relief, and he even smiled widely.

"Seems like you told yourself a good joke."

John's eyes moved up and he groaned. Maybe he should ask (Y/N) if they could meet up in a cafe, or somewhere that wasn't on Baker Street.

"Sherlock, you need to behave."

"I behave all the time," Sherlock said, a little amused.

John ignored him and went to see if there was something to eat with the tea.

(Y/N) walked down the street, lightly bouncing on her feet. She was happy to receive a message from John after all the years, it must have been several years since their last meet up. She smiled at the people passing by and turned to look on the other side of the road. She frowned quickly and she froze. A man with the lower half of his face covered in a black bandana was running after a young woman. (Y/N) knew she should do something, call a police or run and tackle the man, but her head wasn't working and she was stunned by sudden fear.

BAM!

A gunshot. (Y/N) could imagine how the woman was lying on the ground with a deep, bloody red hole on her head. Her legs finally started moving and even if she was terrified, she jogged in the direction she heard the sound come from. Shocked people ran away from the scene, but (Y/N) kept on going. A few curious individuals had stayed to see the woman closer and (Y/N) pushed through them. She gasped. The woman, who was shot on the back, was dead.

"Sherlock Holmes."

John had crossed his arms and stared at Sherlock.

"Of course, I was getting bored already."

He didn't have to guess once what the phone call was about. He wasn't that dumb. Sherlock was heading for the coat rack and John got up, reluctantly. He was waiting for (Y/N) to arrive any moment now but he had work to do. He secretly hoped this would be only Sherlock's business and that he would tell him to stay home.

"Who was that?" he asked, doing the weird balancing on his feet.

"Lestrade. We have a possible murder case."

Okay, he didn't tell him to stay home. John took his own coat and followed Sherlock downstairs.

(Y/N) was sitting in the corner of the pavement, waiting for a police officer to talk with her. She was shaking and breathing rapidly, maybe she was in shock. Her eyes moved quickly, up, down, left and right. She was afraid the danger wasn't over yet.

"John!"

(Y/N) noticed a familiar man on the other side of the yellow police tape. She got up and ran to him, happy to see something that made her feel truly safe.

"(Y/N)? What are you doing here?" John asked when he noticed her. "Are you alright?"

She started to cry when the tension eased.

"I-I'm alright... But I heard a... gunshot and then… she was dead!," she sobbed, not bothering to find a tissue. John held the tape up and he and Sherlock entered the crime scene.

"Calm down, now," John spoke in a comforting tone and hugged (Y/N). "Have you talked to the police yet?"

"No, I was waiting for them to come to me. But why are you here?"

"John, I need an assistant who can solve a murder, not an assistant who comforts girls on the street!"

If John wasn't on a public place he would've punched Sherlock's face off. He pulled back from the hug and looked into (Y/N)'s eyes.

"My... flatmate has a thing for murders."

(Y/N) didn't find the words to react. She followed John, looking at Sherlock, who was busy staring at the body. She wasn't as frightened anymore and she actually could look at the woman more closely.

"Who is this? You know I can't concentrate when there are too many people fussing around," Sherlock said coldly.

"This is (Y/N), a friend of mine. (Y/N), this is Sherlock, a crazy sociopath who likes crimes."

"What have you found?" John asked, ignoring Sherlock's complaints. He wouldn't tell (Y/N) to get lost.

Sherlock looked at (Y/N) for a moment before turning back to the victim. "She's an American on vacation. Ordinary office secretary. She drank to much beer last night and she was on her way back to her hotel from an unfamiliar man's home."

(Y/N) was looking at the woman's scarf. It was a blue, marble patterned chiffon scarf with dark blue embroidery in on of the corners. John noticed (Y/N) was being weirdly quiet and looked at her, wanting to make sure she was doing okay.

"What is it?" he asked.

"I have a scarf like that," she answered, not sure why a random fact like that would matter.

"Mind if I take a look at it?" Sherlock suddenly got up. "It's the only thing I don't understand."

"What do you mean? You're not dragging her into this, are you?" John stood up for (Y/N), but she cut him off.

"It's alright, John," she calmed in down before turning to Sherlock. "I can get it from home."

(Y/N) looked at the other man smiling.

"And then we can have a cup of tea."
