The first case

Dani

Sherlock got out of the cab and stood by the door while Dani slid out after him. It was darker than before and when they paid the taxi driver and walked towards the crime scene. The road was crowded with 3 police cars, a police forensics van and officers making sure the public didn't get too close to the scene. Sherlock's face lit up as he picked up the tape and walked under it. He held it long enough for Dani to crouch under.

"Excuse me, you can't cross the tape." A young officer said as they walked to the house with policeman around the door.

Sherlock sighed "where's Lestrade?"

The officer pointed towards the house and Sherlock stalked off leaving Dani with the officer. "Sorry" she muttered following him. The officer stood looking confused, Dani caught up with Sherlock.

He stopped by a three people, a pretty coloured woman with curly hair, a boring looking man with dark hair and glasses and the man she tricked earlier into buying her coffee. She ducked her head in embarrassment, trying to hide the pink that was spreading across her cheeks.

"What's the case?" Sherlock said automatically and all three turned to face him.

"Suicide" the boring looking one replied.

"Boring" Sherlock bellowed, turning to walk away.

"A suspicious suicide" the coffee shop man said quickly, Sherlock paused and turned back to them.

Anderson cut in quickly "but a suicide none the less"

"Shut up Anderson" Sherlock said quickly.

"I don't see why you called the freak" the woman said harshly, glaring at Sherlock.

"Donovan" the coffee shop guy snapped.

"Whose this?" Anderson asked, leaning forward to take Dani's hand. The other two leaned forward to see her.

"Dani" she answered quickly.

Sherlock interrupted "Danielle, this is Detective inspector Lestrade" he gestured towards the guy from the coffee shop "and Detective inspector Donovan"

Donovan shook her hand "She's not another companion is she?"

Dani's mind floated back to John and before Sherlock could reply she interjected. She hated the fact that they were treating him with no respect (except Lestrade)"No, I'm his girlfriend."

They gaped at her. Sherlock turned around with a questioning look and she smiled at him reassuringly.

"I didn't know you had a girlfriend Sherlock. I didn't know that you dated" Lestrade said softly, Dani let out a small laugh.

Donovan looked surprised "how did you two meet then?"

Dani froze, she didn't know what to say. "I know his landlady"

Sherlock sighed "Danielle moved in yesterday."

Anderson's jaw hung low, he shook his head and continued "You're barely legal."

Dani jumped in "I'm nineteen actually and a university student." They gaped at her, most likely unable to believe that Sherlock was capable of having such a young girlfriend. Who was a babe, if she was totally honest with herself. "I thought we were here for a suicide not small talk."

Sherlock nodded and Lestrade agreed "She's in the attic." Sherlock walked in leaving Dani trailing behind him with Lestrade.

"Danielle, what was that about in the coffee shop earlier?" he asked as she reached the first set of stairs. She looked down at her feet embarrassed.

"We were playing dares, sorry" she mumbled.

"Dares? With Sherlock?" he questioned, she nodded as she continued up the stairs.

"What is Donovan and Anderson's problem with Sherlock?" she asked curiously.

"They don't take kindly to outside help and they don't agree with him methods." He said.

She simply shook it off and continued upstairs. When she reached the attic, Sherlock was examining the body with a small magnifying glass of some sort. She watched as he crouched beside the body. A woman was laying on the floor on her front, wearing a pink coat and shoes, she also had a pink manicure. One of her hands outstretched, next to a carving in the floor, presumably made by her while she was dying.

"OD?" she asked casually, Sherlock looked up for a moment before looking back at the woman on the floor.

Lestrade whispered "Yes, how did you know?"

Dani shrugged, "no blood or physical wound except her nails which are bloody from writing the message. It was either poison or some sort of drug. She doesn't seem like the drug type but she had no means of ingesting a poison and then making her way up here."

She felt someone brush up against her and looked to see Sherlock standing beside her. "A copycat from the woman in pink case, nothing special, the killer has made the same mistake as the previous murderer."

"What mistake?" Dani asked hopefully, looking up at Sherlock's pale face.

"You tell me" he stated, bringing his gaze down to hers.

She took in the scene around and breathed heavily. His gaze was distracting and hot on her face. Her mind screamed at her to lean in and kiss him but she thought against the idea and focused on the woman in pink. "That's it. The woman in pink, her bag isn't here which means the killer still has it. A man with a pink bag." She beamed, turning to Sherlock who was staring at her with a small smile on his face "did I do good?"

"Your very insightful" Sherlock said simply "were done here." He grabbed her hand and lead her from the room, they walked down the stairs in silence and he pulled her gently outside to where Donovan and Anderson stood talking. Sherlock and Dani pushed past them and stood outside the house.

They stood adjacent to each other, inches away, he leant down "What was that about?" he snapped.

"Be quiet" she said quickly, Lestrade came out of the house and stood with Donovan and Anderson, they were all staring. She could see their lips moving but couldn't hear what they were saying.

Dani put her arm on Sherlock shoulder and pulled his lips onto her own. He bumped against her clumsily and she smiled as she pushed on his lips.

The kiss was rushed and clumsy, she had surprised Sherlock with the kiss. She pulled away and began to walk down the street, he followed her.

After they had ducked under the police tape and walked down the street a bit, Sherlock grabbed her arm and pulled her to a halt.

"What was all that about?" he asked, his voice tainted with anger.

"They were being mean to you Sherlock, calling you things to your face and you didn't even bother to stand up for yourself. You're a great person and deserve respect, I just surprised them."

"How did you know it would work?" he asked, breathing out to avoid sounding too ungrateful.

"Are you serious Sherlock?" she blinked at him and when he didn't answer she continued "Sherlock there's one thing I know about people, they are shallow. So when they saw you with a young, hot student it sparked their interest and made them jealous."

"How did you know it would work?"

"I thought you were meant to be the smart one" she said mockingly "I understand people and I understand how men's minds work especially when it comes to women. I think you need to clear out your mind palace and store some more basic knowledge, like how to treat people."
