Chapter 1:

Hayden's POV:

"Goodnight Hayden my sweetheart" said Mom kissing my forehead and pulling the duvet cover over my body. Mom moved over to Tristan and did the same. Tristan is my twin brother and we do everything together and we are separated at all. Mom smiled and turned off the light. I closed my eyes as I heard her head for Nico and Jason's room.

It was an hour later that I heard screaming, my eyes were open in a flash and Tristan and I was in front of Tristan ready to protect him when the door opened and there stood a man with a gun. I threw my pillow at him and reached for the gun that I his under it, I fired and he fired. He collapsed dead and I turned to Tristan who had a blood splatter behind him. My eyes widened as he slumped to the floor with a bullet hole in his head.

I woke up from the flashback and the sun was shining through the window. After our parents, my twin brother and our younger brother Jason were murdered that night, Nico and I left after the cops questioned us both. We traveled to New York from Las Vegas and bought an apartment with the money left over from our inheritance. I could not believe that my twin brother Tristan was dead. Nico was there beside me after the murders.

I got out of bed and headed for the shower to freshen up. After my shower I dressed in loose blue jeans, a tank top that showed off my six-pack, my leather jacket, trainers and I even gelled my hair up like I do every morning. My hair was blonde with dark red highlights. I smiled and headed to see if Nico was awake.

"Nico!" I shouted and I heard a mumble from under his covers, I threw back the covers and he opened his eyes,

"What?" he asked angrily still not bothering to get up,

"I'm going to head out and buy a new phone and some other stuff" I replied and he shrugged. I shook my head and left the room,

"Have fun!" I heard him mumble from his bed, I picked up my shabby Nokia and texted my best friend Seth,

Goin out 4 the day 2 town u wanna come? I hit send as I locked the apartment door. It was a Saturday and I didn't have to got to work which relived me. I put my phone in my pocket and headed for the lifts, I passed an old lady who stopped me,

"How old are you son?" she asked,

"15 going onto 16 why?" I replied and she smiled,

"Are you looking for a part-time job?" she asked and I shook my head,

"I'm not but my brother is should I pass on the message?" I asked and she nodded,

"Yes" and she continued walking,

I reached the lift and my phone went off. I took it out and it was Nico ringing,

"What do you want now, please don't say it's becuase you don't know how to fry sausages?" I said,

"No but you need to come back" he said and hung up. I shook my head and headed back to the flat. I opened the door and saw no-one,

"Nico?" I said looking in his bedroom and there was no sign of him.

"Nico?" I shouted this time I heard a shuffle from my room. I opened it and found a man in a ski mask fighting my brother,

"OI, get off my brother you fool!" I shouted pushing him, he fell sideways and got back to his feet, I pulled Nico behind me like I did 2 months ago with Tristan but this time I was sure that Nico was not going to die although the man had now pulled out a gun. I kicked out and the gun crashed to the floor, I picked it up and pointed it at him.

"Who are you?" I asked and the man shrugged and lunged at me, I dodged and he fell crashing into our coffee table which moved, I kept the gun poised on the intruder,

"Nico ring the police" I said and Nico nodded.

The man got to his feet and got ready to lunge again, this time when he lunged I hit across the head with the gun and crumpled to the ground. I stepped back as a pool of blood spread across the floor. My eyes widened and I stepped back dropping the gun. I turned to Nico knowing that there was not much time left. He understood and grabbed our bags and we ran out of the flat luckily no-one saw us. We ran down the stairs and I fiddled around trying to find my car keys. We went into the car park and we slowed down aware of the CCTV cameras that we professionally dodged all the way to my car. My car is a Metallic Red Lotus. I got into the drivers' seat and closed the door. I shoved the key in the ignition and drove out of the car park.

Mac Taylor's POV:

My phone rang and I looked at the caller ID

"Stella what is it?" I asked down the phone,

"There's been a homicide" she replied and I shook my head,

"Where is it?" I asked,

"The block of flats down from where you live" she replied and I nodded,

"I'll meet you there" I said and she hung up.

I grabbed the kit and my keys before waking Sheldon up,

"Sheldon we have a homicide" I said and he shot out of the couch and headed grabbed his clothes and got changed.

"Why didn't you ring me Mac?" asked Sheldon and I smiled,

"You were asleep so I wanted to leave you alone for a bit" I replied and he nodded. I grabbed my long coat and headed for the car.

"Are we going straight there?" he asked and I nodded getting in and closing the door. I shoved the kit in the back seat and turned on the engine.

Sheldon got in and turned on the siren and I drove as fast as I could to the Crime Scene. Don Flack was already waiting.

"Mac, the victim and the killer were having a fight, the apartment is absolutely trashed." stated Flack and I nodded.

"Any witnesses?" I asked and Flack shook his head,

"No, apart from the next door neighbour heard a fight going on and saw the victim bursting in wearing a ski mask." said Flack,

"So the victim is also the attacker, do we know who the flat belongs to?" I asked as we made our way to the apartment. Flack looked at me,

"Yes, it belongs to Hayden Martez, our Crime Scene cleaner" replied Flack and I nodded remembering how eager Hayden was when I mentioned that there was a job going. I became fond of the boy even at his age. I entered the flat and was stunned with what I saw. A lot of things were smashed and broken and the coffee table was in pieces.

"Wow" was Sheldon said before moving over to the body. I looked over to where Sheldon was examining the body,

"Any ID?" I asked and Sheldon shook his head.

"No, but COD is blunt force trauma to the head that was caused by this gun. But there is a sign that this was done because the killer was protecting himself." replied Sheldon,

"So the killer killed the attacker in self-defense?" I asked and Sheldon nodded. I walked into the room that must have belonged to Hayden. I noticed that there had been a struggle. I turned to Flack who was watching me,

"Who rang 911?" I asked and Flack looked at me,

"His brother Nico Martez. Police say that Nico rang and called for the police and Nico mentioned someone in the house and that he was scared that his brother would get killed" Flack replied and I nodded. Now Hayden killing the attacker in self-defense was the case but now we have to find him. I turned to Flack,

"I suppose you don't have a clue where he has gone" I asked Flack and he nodded. I put on my gloves and picked up the picture of Hayden and Flack picked up the picture of Nico and Flack understood what I was thinking.

We went under the crime scene tape and knocked on the door by the lift. A young woman answered,

"Hello?" she asked,

"I'm Detective Mac Taylor and this is Detective Don Flack, I don't suppose you know where this boy has gone?" I asked showing my badge and the picture.

"No I don't but my boyfriend might" she replied returning to the flat and a stocky muscular man replaced her,

"What do you want?" he asked,

"Your Girlfriend told us you might know where this boy has gone" Flack said flashing his badge,

"Yeah, he might be in Hyde Park raising money or in Grand Central Station getting money by showing off not that he gets much from what he does for a job. Me and Hayden are good mates. He told me that he had to go out during his days off work and the week-end trying to reign in more money to pay the rent and feed his brother he told me that they would be living in his hide-out up on the roof." said the beefy man and I nodded.

Heading back to the crime scene, I turned to Flack,

"Hayden never showed that he was short of money but there again he never complained" I said to Flack and he nodded.

"I like Hayden but we really need to get him" he replied and I nodded as my phone went off. I checked the Caller ID and it was Unknown, frowning I answered it,

"Mac Taylor" I said.

"I know your after us but I can't get over the fact I killed someone and if you come after me I'll run and you'll never find me. I lost everything when my parents and three brothers were murdered in Vegas. I have nowhere to hide and they'll kill me I'm sorry Detective Taylor, I really am" replied a familiar voice and then he hung up.

"Who was that?" Flack asked and I turned to him.

"That was Hayden Martez" I replied and Flack smiled.
