The three walked in an open field. They could feel the moist grass being crushed beneath their feet, and Roxanne quietly blessed herself for not going with heels just this once. Donovan, on the other hand, hadn't made such a decision, and she struggled not to stumble.

A man's body laid on the grass, under a large Ulmus tree, facing the sky.

Donovan, frightened from his wide-opened eyes, tried to stay as far from the body as possible.

"You start." Roxanne said to Sherlock, still unfocused and thinking of the decision she must make.

The detective bent over the corpse.

"Around thirty years old. One stab to the shoulder, made by a butcher knife. Multiple stabs to the heart, made by the same weapon."

As he finished describing the body, he frowned. The situation was familiar to him, for some reason. He thought of entering his mind palace, that perhaps this would lead him to the answer, but after just a second someone else reminded him where he had seen this before.

"No. No, this isn't possible. This can't happen." the red-headed said in shock and confusion, and took a step back from the body.

"What happened?" the doctor asked worriedly.

"This is why the description is familiar to me, isn't it?"

"Lift up his shirt." she urged nervously.

"What?" Donovan asked confused.

"I said – lift up his shirt." her voice was trembling, like her hands.

The doctor bent over the corpse and uncovered the man's stomach. As he did, a large and long cut was revealed.

Roxanne gasped, and put her hand to cover her mouth. She was shaking, her cheeks were blushed, and her eyes were filled with tears. But those weren't tears of sorrow, nor of pain. They were tears of true terror.

"No, no, no…" she started murmuring and started shaking her head.

Sherlock immediately got up and walked to her.

"Sherlock – what's going on?"

"This man's cause of death, this man's murder, is exactly identical to one of her murders. She killed a man under exactly the exactly same circumstances once."

John was startled, but Donovan was still in the dark.

"So? This doesn't necessarily mean anything."

Sherlock glared at her. He opened his mouth to yell at her, but Roxanne started talking before he managed to.

"This could have been insignificant, if it wasn't for the cut in his stomach. This…" she took a deep breath and tried to calm herself down, as her voice was shaking too much to speak. "This cut, it's my signature. I make this cut in everyone I kill."

"Killed." John corrected.

"Why?" Donovan asked, a bit tactlessly, but that was the question that was in Sherlock's mind as well.

The woman pulled her shirt out of the skirt she was wearing and lifted it a bit. She revealed a long, ugly scar, of a cut identical to the one on the body.

"Funny, isn't it? The only survivor of a serial killer, becomes one herself. A bit ironic when you think about it." she said with a frantic smile.

"You didn't tell me." Sherlock whispered.

"You never asked." she said with a shaking voice, and as she tucked the shirt back in the skirt, she started crying quietly.

"So why did they do it?" John asked. As bad as he felt asking this, they had to solve it.

"They want me to leave." she said quietly in agony.

"What? Leave?" Sherlock asked, a bit shocked, but mostly angry.

"Lestrade's coming back tomorrow. I can either stay, or move on to the next police station that needs my help. Whoever did this clearly want me to leave."

"Well, you're not leaving."

"I have to, Sherlock."

"No, you don't!" Donovan burst. "We'll find whoever did this, and we'll arrest him, and you'll stay. Did you hear me?"

The men were surprised by her reaction. Neither of them knew she cared so much until this very moment.

"Did you hear me?" she asked again, as her friend didn't answer.

Roxanne stood there, staring at the body in silence. She didn't answer. In fact, she didn't seem to hear them.

"Alright, it seems we're not investigating today." Sherlock said, and put his hand around her.

"But we have to catch him – whoever did this!"

"Not today."

The detective and the girl he loved walked away from the large tree, and after a moment and an apologizing look towards Donovan, the doctor quickly followed them.
