*Sherlock's POV*

I paced the floor, tension running high. "Sherlock!" I only made a grunt, telling John I was listening for them moment. "Have you seen my phone? I've been ringing it but-"

"Cassandra has it." I saw out of the corner of my eye that he sighed, looking down and shaking my head.

"Should I even bother to ask why?" He ventured and I sighed, stopping as I faced the glass doors to the patio, back to him.

"I gave it to her because she was breaking into a apartment." He sighed as I said this.

"Well, where is she now?"

"She hung up on me, and I haven't heard from her since." I sighed and put my hands on my hips.

"Great. Now I need to get a new phone." He muttered and I glared at him over my shoulder.

"She could have been either kidnapped or killed, and all your worried about is your phone?" He stared at me as I at him.

"What the real question is why you care." I clenched my jaw, then looked back to the patio.

"Noooo." He nearly whispered, and I sighed.

"What?" I asked sharply, only to have him come next to me, staring at me.

"You… No…" He licked his lips before continuing, my patience running thin. "You feel…. Guilty, don't you?" He said, and I paused for a minute.

"No." I deadpanned, looking back out the window. "We just need to get that killer. And figure out why he killed Colson." As I said this my phone went off. I grabbed it and glanced down at the screen.

"What is it?" John asked, but I ignored him as I opened the message and read it.

"Just Lestrade trying to tell me to leave the case alone." I said and tucked the phone back in my pocket, the message pulsating in my mind.

Café. 2 AM. Come alone or girl dies.

I walked into the dark Café that Cassandra and I went to. I looked around in the dark, not seeing anyone. "Did you decided to skip?" I called out, only to be rewarded with a cry of pain. My head shot to the kitchen door where a light was on, knowing that scream came from Cassandra. Then out walked the Hispanic was served us that first day we met. "I see." I murmured, watching his movements.

"Yes. Even the great Sherlock Holmes couldn't figure it out." He said proudly, and I wanted to sneer, but kept my face calm.

"Well, I get it now." I said and his face fell. "You were having an affair with her, weren't you?" I questioned and he smiled.

He held his arm up. "Shall we chat in better light?" He asked as he pointed to the kitchen.

"Let's." I said coolly and we both walked to the kitchen. I saw him close the freezer door before he turned to me, black eyes shining. "So, what's the master plan? Affair gone wry and you needed an out before she told her husband?" I said and he laughed.

"Not quite. Try meth makers/sellers." My eyes narrowed at that.

"So, you stopped her before she could tell?" I asked and he smiled.

"Finally got one right!" He congratulated but I only glared.

"So, I'm guessing I'm going to have to kill you now because your not going to come quietly, are you?" I asked, and he smiled slowly

"Your catching on." He raised his arm, a gun in his hand. "But you have nothing and I have this." With that he smiled. "Goodbye you nuisance."

In a split second, he pulled the trigger and I ducked to the side and I pulled John's gun from my waist. The bullet grazed my cheek as I shot behind him, me watching as it hit the metal freezer door and recoiled and lodge itself in the back of the waiter's head, killing him instantly. I stood up straight and straightened my jacket as he fell to the floor, dead.

"How boring." I murmured as I walked over to the door and opened it, seeing Cassandra laying on the ground, skin blue. I walked in and picked her up, walking out and sitting down on the floor, warming her up with my jacket.

"Sherlock?" She shivered opening her eyes to look at me.

"How do you feel?" I asked trying to see if there was any pain to make sure he didn't break any bones.

But then she did the oddest thing. She smiled. No one but me would come out from a situation like this and smiled. I just stared at her with an odd look as she passed out, unsure of who this girl truly was.
