Steve looked down at the young Williams.

"He went inside to take a phone call. He shouldn't be too long." Steve told Charlie.

Just as Steve had finished his sentence Danny came out of the house. Catching Steve's eye Danny tilted his head hinting to his partner that he needed a word in private.

"Grace, keep an eye on your brother while I go and talk to your dad." Steve instructed as he excused himself from their company.

"Danny? Is everything alright?" Steve asked when the two of them were out of ear reach from the others.

"Yeah, course. But, I'm gonna need you to look after the kids for me. There's something I need to do." Danny explained.

"Of course, no worries. You know I don't mind looking after them. But, are you sure everything's okay?" Steve asked again, concern etched across his face.

Danny smiled as he patted Steve on the shoulder.

"Yes. So there's no need to have your aneurysm face on." Danny told him with a grin.

"I do not have an aneurysm face on." Steve called out as Danny walked over to his kids.

"Grace, Charlie?" Danny called ignoring Steve. "Danno's has to go and deal with something so you'll be staying with Uncle Steve for the night."

This announcement was received with a squeal from Charlie and a tight hug from Grace. Danny chuckled slightly. Then kissing each of them on top of their heads, saying goodbye to the cousins he left the lanai.

The next morning arrived. Steve arrived at the Palace and noticed that Chin and Kono were already there. However, as he pulled into his parking space he noticed the Camaro wasn't in its parking space. Checking his phone there weren't any missed calls. It was unusual for Danny not to call if he was running late. Walking into HQ Steve noticed Kono and Chin by the table lost in conversation.

"Morning, guys." Steve announced as he came up beside them.

"Morning, Boss." Kono replied.

"Morning, brah." Chin said.

"Danny's not in?" Steve asked.

"Nope. Cars not in its spot." Chin told him.

"Is everything alright, Boss?" Kono asked when she noticed Steve's expression.

"I'm sure it's nothing." Steve said dismissing the worry that was creeping up on him. "But, just for the sake of it can you put a trace on Danny's phone?"

"No problem." Chin said as he began tapping his fingers on the screen.

Within minutes there was a sharp ping. Chin's brow creased.

"That's weird." Chin said aloud. "It says he's still at home."

Wanting to make sure that nothing had happened to Danny, Steve ordered for the three of them to go over to his home to check. Pulling up at the house, Steve, Chin and Kono slowly got out of their cars. The Camaro was still parked. Creeping up to the front of the house, they didn't noticed anything suspicious. Motioning for Chin and Kono to take the back, Steve pulled out his gun from the holster and nudged the door frame with his shoulder. Clearing both the living room and the dining room, Steve was satisfied there was no damage to any of the furniture until he heard Chin's voice call out.

"STEVE!"

Steve ran to where he found the cousins out in the back. Chin was knelt down on the grass while Kono stood beside him. Steve run up next to them.

"What you've got?" Steve asked, worry coming through.

Chin held something up that made Steve's heart stop beating. Kono let out a small gasp as she covered her mouth.

It was a Five 0 badge with the number 7576.

"Chin call Duke and get him to set up a search. I want this search to be thorough. Kono I want you to head back to HQ and pull up Danny's phone details. I want to know the last person he spoke to last night."

"Last night?" Kono wondered.

"Yeah, just before he left he received a phone call. He didn't say who it was but, when he came out he looked worried. He dismissed my concern when I asked. But, I know he was lying."

"We're on it, Steve." Chin said.

"Shouldn't we tell Rachel and the kids?" Kono inquired.

Steve shook his head.

"Rachel and Stan are away at the moment. And I don't want to worry the kids. Not when we don't know everything."

The two cousins nodded their understandings and then departed their separate ways to get on with their tasks. A couple of hours later Chin and Kono were back at HQ tapping their fingers away on the glass.

"Anything?" Steve announced as he strolled in.

"We could have a lead." Chin replied.

"Or two." Kono added.

"Well? What do you have?" Steve asked.

"Duke found a piece of material around the surrounding areas. It's been sent of to Fong in the lab so we're just waiting for the results to come back." Chin explained.

"Kono?" Steve handed over.

"I pulled up Danny's phone call list and the last call he received was from a person called Tommy Matterson. I ran him through the database. Nothing criminal on him. He's a former detective from Jersey. Moved here to the island to be with his mother over a year ago."

"Does Danny know this guy?" Steve inquired.

"There's nothing to link him with Danny. But I'll keep digging through his files to see I can find anything." Kono said.

"And I'll go over Danny's file and see if I can find anything that might give us a lead." Chin offered.

Steve nodded his head when his phone rang.

"McGarrett."

There was a pause.

"Are you sure about that? Right, thanks Fong."

"Steve?" Chin asked, his expression changed.

"Boss?" Kono tried when they didn't receive an answer to Chin's question.

"Uh, that was Fong. The material Duke found around Danny's house had some blood on it."

Kono and Chin stared at Steve.

"It's Danny's blood."
