I've been working on this story for a while, and finally got to a point where I thought it was ready to be posted.

Disclaimer: I own nothing but the children. Andrew Marlowe and ABC are the only ones with the rights to Castle. Also, I do not own Harry Potter.

Kate Beckett stepped behind the crime scene tape to find Lanie looking over a dead body.

"What do we have?" Kate questioned once her friend looked up.

"Multiple gunshot wounds on this guy. Don't know that much on the other one."

"There's another one?" Castle asked coming in and giving Kate her coffee. The detective took a sip of her beverage before responding.

"Yeah, a man and a woman." Kate said. "Where was the woman found?" She asked looking back at the medical examiner.

"She was in the back bedroom." Lanie responded. "Taken back to the morgue five minutes before you got here." Kate nodded before motioning Castle to follow her. They went to the bedroom Lanie told them the woman had been in.

"Kinda reminds me of Harry Potter." Castle whispered seeing the crib against the wall and a blanket on the floor. Kate gave him a disapproving look. They looked around the room to see anything that may have been missed when the partners heard a loud cry come from the other room. Taking her gun out, Kate led the way into the other room. When she opened the door, she quickly put her gun back in its holster. In front of the duo were two six year old girls, each with brown hair and blue- green eyes. One held a baby in her arms while they huddled behind the bunk beds. The children's eyes went wide at the sight of the strangers.

"Hi." Kate said sweetly as she bent down to the children's eye level. "My name is Detective Beckett, but you can call me Kate." She pointed at Castle and said, "This is my friend Rick Castle."

"Rick." Castle commented so the girl could know what to call him.

"What's your name?" Kate questioned. The twins stared at each other a moment before the first one nodded her curly haired head at the other.

"Cassie." The first child responded softly. "Do you know who took my mommy?" Kate looked up at Castle for reassurance. He placed a hand on her shoulder and she looked back at Cassie and her siblings.

"My friend took her to my work." Kate replied simply. Cassie nodded and looked over at her sister who was crying silently.

"S'okay Lanie." Cassie reassured her twin. Lanie nodded as she gave her sibling to her sister. Cassie gave her sister a questioning look.

"My arms are tired." Lanie replied. Cassie nodded and took her sibling.

"May I see him?" Kate asked the children. Again, the girls looked at each other before silently agreeing. The baby was passed to Kate.

"His name is Corbin, but we call him Corby." Lanie said as she handed her brother to the detective.

"How old is he?" Castle queried watching Kate gingerly take the child.

"A year." Cassie and Lanie responded together.

"We need to take you girls with us okay?" Kate said softly. The girls nodded, Cassie grabbing Kate's hand and Lanie grabbing Castle's. The detective and writer came out of the girls' room to find Esposito and Ryan coming into the living room.

"Can you guys look after the scene?" Kate asked as she nodded to a sleeping Corbin she held in her arms.

"Yeah." Esposito said. Kate thanked him before asking the girls to tell her where their brother's car seat was kept. After taking them to Kate's car, they realized the ride back would be a little cramped.

Review please!
