On our way to visit the wife, I noticed that a white van had begun to follow us.

"Tony" I say, calmly. "We're being followed."

"I know." He says, gripping the wheel even tighter. "I'm going to take a detour to try and shake him. You call Gibbs."

I take out my phone and dial Gibbs' number.

"What do you need Kate." Gibbs answers

"Gibbs, Tony and I are on our way to the wife's house and we are being followed by a unlabeled white van. Tony's taking some detours to try and shake him. I'm thinking that we should protect his wife, if whomever's behind us wants to find her."

"Good call, you and Dinozzo are on protective detail from now on. Shake the van and get to her house."

He hangs up.

By now, Tony is in an alleyway, and he's turned off the car.

"Gibbs wants us on protection detail."

"Okay." He says, but doesn't start the car or move.

"Tony, what-" I start, but then the white van flies by in front of where we are, in the opposite direction of where we're going.

"Nice job Tony." He mimics what I should've said, as he turns the car back on. I elbow him, mildly annoyed, but rolling my eyes in amusement.

We pull out of the alley and starts towards the wife's house.

We arrive no more then five minutes later and she greets us at the door.

"Hello ma'am, we're special agents Anthony Dinozzo and Kate Todd. We're here to protect you and talk about your husband." Tony states

"Please come in." she says, stepping away from the door.

We walk in and she shuts it behind us.

"I'm Dr. Jessica Waterfield, though I believe you already know that."

I nod.

"I believe someone has been watching the house, starting last week."

She says

"Tony, perimeter." I order, and to my surprise he does as I say.

Dr. Waterfield leads me into her livingroom, where we sit opposite each other on the couch.

"Do you know where your husband is?"

"No, and I doubt he'll be gone long. He has to take our daughter to Ballet."

"You have a daughter?" I ask, a daughter had not been mentioned in any of Staff Sergeant Waterfield's files.

"Yes, she's not quite 3. Shannon. Evan didn't want anyone knowing about her because we weren't married when she was born…" she trails off "Please don't let anyone where Evan worked know."

"I wont, your secret is safe with me." I smile at her

"Thank you."

Then Tony walks in.

"I checked the perimeter and upstairs, no sign of anyone. Gibbs called, told me you should take first shift, he needed me to help McGee back at NCIS. I'll be back in six hours."

I get to say hello to Shannon, a beautiful and sweet little girl with ginger curls and blue eyes. Dr. Waterfield asked if I could watch her for just a few minutes while she took a shower, and I told her I would love to.

Now, I am curled up in a chair, Shannon in my lap, as I read her a book.

"I do not like green eggs in ham, I do not like them Sam-I-Am!" I say, and as I do, I bounce my legs with each syllable making the little girl giggle.

"Do you like them in a house? Do you like them with a mouse?" I read "I do not like them in a house, I do not like them with a mouse."

"Want to say it with me?" I whisper to the girl

We both go, bouncing together, "I DO NOT LIKE GREEN EGGS AND HAM I DO NOT LIKE THEM SAM-I-AM!"

She shrieks with laughter, and so do I, hugging her tiny body closer to me.

"Looks like you two are having fun." Chuckles a voice from the doorway.

"Hey Tony." I say, looking over at him. "This is Shannon."

He waves at her and she shyly waves back.

"Hey Shannon, would you like to watch a movie with Tony? What about the movie you were showing me earlier? Lady and the Tramp?"

"Yes! She leaps out of my lap and takes Tony's hand, dragging him toward the television screen.

I smile as I watch her go, Tony smiling in surrender to the assertive three year old.

"Bye Tony!" I laugh

I walk upstairs "Dr. Waterfield? My partner, special agent Dinozzo, is going to be here from now on. I'll be back a little later." I call

There's no response.

"Dr. Waterfield?" I call again.

Sensing something might be wrong, I pull my gun out, but I keep it by my side.

I edge towards the master bedroom door, and fling it open, to find Evan Waterfield with a briefcase open on the bed, full of what looks like prescription pain meds.

"What-?" I start asking, when something hits me on the back of my head, hard.
