At was about 15 minutes later that Jack came in, shivering from the brisk wind that was blowing outside.

"Morning." he called, oblivious to the tension between Martin and Sam.

"Morning." replied the others.

"Danny not here yet?"

Vivian shook her head. Just then the phone rang, "That might be him." she added picking it up.

"Hello, Agent Johnson."

She paused listening to the person on the other end, a frown coming over her face. The others watched anxiously.

"Ok. We'll be right over." She hung up the phone looking over at the others.

"That was Danny. His neighbour's little boy has gone missing. I said we'd be right over."

"Alright, Martin, you and Sam take one car and go to Danny's neighbours. Viv and I will follow."

Martin and Sam exchanged uneasy glances, but were unwilling to ask Jack to change partners knowing it would promote a lot of questions.

"Sure." replied Samantha, and Martin nodded.

The two of them walked stiffly out of the office, not talking and acting all coupley like usual. Vivian looked after them concerned. Jack threw Vivian a curious look, "What's up with them?"

Vivian shrugged, not wanting to tell Jack anything without talking to them first.

"Oh, before I forget. I told Sam that we would check if Riley has had any more visits from Perry."

"Okay, I'll call them quickly now." Jack quickly found the number on one of the computers database. "Here it is." he said picking up the phone and dialling.

"Hello, this is Special Agent Jack Malone, a few days ago myself and my colleague came to see James Riley." There was a short pause. "Could I please find out if he has had any visits from a Ben Perry recently."

There was another pause, Jack listened to the person and frowned. "Alright then. Give me half an hour." He hung up and turned to Vivian.

"They won't tell me over the phone, so I'll have to go over there, might see Riley briefly too. I'll meet you over at Danny's as soon as I can."

"Alright." said Vivian. "See you soon and errr keep your temper alright?"

"Of course." replied Jack smiling.

Vivian smiled back and walked out to go to Danny's place.

"Hey, where's Jack?" asked Martin when she got there. He was waiting outside and Danny and Sam were a few yards away.

"He's stopped off at the prison, he's going to see Riley."

Martin shot an glance at Sam. "Has something else happened?"

Vivian shook her head. "Jack's just going to see if Perry's been visiting again."

Danny and Sam joined the others. "Jack coming?" asked Danny.

"He'll be here soon, he's just going to see if Perry has been visiting Riley. So what have we got?"

"My neighbor, Jill Fox. Her son, Ben was in the car with her, which is there," he said pointing to a car just next to them, that had police round it. "She dropped a letter just by the door and went back to get it, when she came back Ben was gone."

"How old is Ben?" asked Martin.

"He's three."

"Any suspects?" asked Vivian.

"Jill thinks it's her ex-husband, she's given us his address and everything."

"Does Ben see his father a lot?" asked Samantha.

"I think so, almost every weekend." replied Danny.

"So if it was his dad, then he'd probably go willingly?" she questioned.

"That would explain why there are no signs of a struggle." added Vivian.

"That's most likely." replied Danny.

"Well," said Vivian taking charge seeing as Jack wasn't there. "Danny if you and Samantha go and see the father. Martin and I will wait here for Jack."

"Alright." said Danny.

"I'm driving." said Sam, grabbing her keys and walking over to the car followed by Danny.

"What's the address?" she asked Danny once they were in the car.

Danny glanced at the paper, "It's on the other side of town. 56th and Connecticut."

"Right." replied Sam, she looked out the rear window as she pulled out catching a glimpse of Martin watching the car drive away. She sighed sadly.

"What's up?" asked Danny hearing the sigh.

"Nothing." she said sharply.

"Sam, c'mon you can't fool me."

"Well you're going to figure it out soon enough. I broke it off with Martin." She kept her gaze firmly fixed on the road, not wanting to look at Danny.

"Why?" asked Danny surprised. "I thought everything was going fine."

"It's complicated....Can we not get into this now. We've got a kid to find."

"Sure." said Danny, backing away from the subject.

A while after Danny and Samantha had left, Jack pulled up outside the apartment buildings. Seeing Vivian he headed over to her.

"So what's going on?" he asked.

"We've got a little boy missing, Danny and Samantha have gone to talk to her husband." she said nodding at Jill who was standing talking to Martin.

"What did you find out at the prison?"

"Riley has had several more visits from Ben Perry. I talked to Riley, he still won't say much."

"You think they are planning something?" asked Vivian worried.

Jack sighed. "I think so, Riley didn't say anything per say, but he hinted that Sam should look out. Well his exact words were that, 'that bitch should start watching her back.'" During this Martin had excused himself from Jill and walked over to join Vivian and Jack and managed to catch the end of Jack's sentence.

"Is Sam in danger?" asked Martin.

"It's hard to say, she should definitely be careful though."

Martin frowned, looking away from them in the direction that Sam had driven off in.

Meanwhile, Sam and Danny had arrived at the father's house. Walking up to the door, Danny knocked, nothing happened for a few moments so he knocked again. They heard a noise from inside, and the door eventually opened.

"Derek Fox?" asked Danny.

The man nodded, "Can I help you?"

"I'm Agent Taylor, and this is Agent Spade. We're with the FBI."

"Can we come in, we'd like to ask you a few questions." Sam took over.

"Sure." replied Derek.

"You were married to Jill, and you have a son Ben. Right?" said Danny.

"Yes, what's this about?" he said growing obviously nervous, something that was noticed by both Sam and Danny.

"Ben went missing this morning. You wouldn't know anything about it would you?"

"No." he replied.

Samantha raised an eyebrow at him. "Where were you at 8:30 this morning?"

"H-here." he stuttered.

"Can anyone verify that?"

He shook his head.

"Do you and Jill still have a good relationship?" Danny asked suddenly.

"Yeah I guess."

"So you see Ben quite a lot?"

"About every other weekend."

"Do you wish you could see him more?"

"I guess so...you don't think I took him just to spend more time with him?"

"You don't have an alibi, you've got a motive."

Derek was becoming increasingly agitated, and stood up suddenly startling Danny and Sam. He was sweating and his eyes darted around the room.

"Why would I take my own son?!" he yelled glaring at the two agents.

A small noise was heard from down the hall. Derek paled, "Just leave." he said quieter.

"What was that?" asked Samantha, peering down the hallway.

"Just go." he said again grabbing Samantha's arm pushing her towards the door.

Samantha pulled her hand away, moving back into the room. "What was that noise Derek?" she asked again, amazing Danny with her calmness.

Danny cautiously put a hand on his gun in case Derek got violent.

"It was nothing-" He was cut off as a small figure crept into the room.

"Why are you yelling Daddy?" asked Ben sleepily.

Samantha turned to Derek, "So you wouldn't take your own son?"

"She doesn't deserve him." replied Derek angrily. "She left me with nothing."

Danny knelt down beside Ben. "Hi Ben. You remember me?"

He nodded shyly.

"Your mom's very worried about you, you want to see her?"

Ben nodded smiling.

"Okay, my friend Sam is going to take you to the car, I'm just going to finish talking to your dad." Turning to Sam he said "Will you take ben to the car, and call Viv and the others. I'll finish up here."

Sam nodded, walking over to Ben, her gaze fixed on Derek making sure he wasn't going to try anything.

"Hey sweetie, come on lets get you home." she said smiling at Ben. Ben grinned shyly back, allowing Sam to pick him up and carry him to the car.

Danny looked at Derek, who was looking at the retreating figures sadly. "I just wanted to see him more."

"If she doesn't press charges I'm sure you can work something out." Danny sighed. "The police will be here soon, we're going to have to take you down to the station." he said.

Derek nodded.
