Kate POV

How was I going to break the news to Tony? He is going to be so upset. Here goes nothing. I reach up and press Tony's doorbell. A few seconds later, the door opens. I see Tony in his boxers. "Tony put some clothes on."

He ignores that and says, "What do you want I am kinda busy."

What could he be up to? He tells me that he has evidence for the Riley case. He tells me to wait where I am. It won't hurt if I wait inside the door. I push the door open to see Summer, in a short silk nightdress, eating breakfast.

"What do you think you are doing in my house, I said wait outside" he yells at me.

I grab his arm and pull him outside. "I take it you did not know she has been missing since yesterday. She went to visit her grandmother and never showed up," I said in an angry voice.

He looks at me, gives me a brown paper bag and tells me, "I think you should go, I will have a talk with her and do not tell Gibbs. I don't want him to know she is staying here".

How can I tell Gibbs that Summer is safe. He will want to know where she is. Also how can I explain where I got the evidence from. Well I better start this car and go to work.

I sit down at my desk and open the brown paper bag. I put some gloves on and picked up what was inside. It was an empty packet of sleeping pills. The murder weapon. I stood up to take the evidence to Abby's lab. It might have some prints on it. After only a few steps I hear, "Caitlin, why were you late to work today?" asked Gibbs.

Ok, think of a good answer, "I went to see Tony about Summer and I am sure she is safe because she gave me this evidence this morning I am just taking it to Abby" I reply.

He will not believe me.

"Well hurry up. We need to find the killer soon"

Two hours later

"What do you have, Abby" asked Gibbs.

Abby, looking very pleased with herself, replied "Ok, I found a partial print. I ran it through the system with no matches but whoever did this cut themselves on the side of the packet that left DNA. The killer is blood related to the victim" she finished. "But I know it is not Summer from the DNA you gave me from the baby, so it was one of the twins".

Within half an hour, we had both the twins in Abby's lab taking their fingerprints. We had a hit. The killer was…

Who do you think the killer was? Thanks for the reviews.
