*mini-cross-over – Magnum P.I. (you know… Mac)

"One of the old ladies living in this hotel saw a man in a hoodie and baseball cap about 30 minutes before the fire" said Tani, coming over to the guys.

"And before you ask…" added Quinn "she did not see the face and neither did cameras, so we have nada for now"

"Well…" started Danny. Steve quirked an eyebrow at the dramatic pause "The vic was recently retired prosecutor" he finished, giving McGarrett an eye roll.

"So we need to dig through all his cases and see who could do something like this?" asked Liu, already growling at the prospect. They all sighed in unison and walked over to their vehicles, so they could start doing just that in the office.

*three days later*

"Oh… My… Gosh…" exclaimed Lue and banged his head on his desk.

"You ok Cap?"asked Tani from the doorway to his office.

"As good as you…" he said in a gravely tone "three days of research and nothing."

"Yep." *sigh*"but we need to find something… Arson guys found only gasoline at the crime scene. Not exactly helpful – you can get it anywhere…"

"I know. Witnesses didn't remember anything else?"

"None." deadpanned Tani.

"Hey Kid" called Steve "you with me. I think I might have a lead"

Tani grinned at that "Coming Boss."

*in the meantime*

Jay felt bad. He really wanted to help, but neither he, or his neighbors from the hotel haven't seen or heard much. One lady saw a slim guy in a hoodie and a cap, and that's all.

"Grrhhhh…" he groaned "what do I do…" Jay thought to himself. One idea came. And that is why he was kind of stalking Five-0 for two days, but it didn't help.

"Well… May be Voight will give me some idea" … he decided Skype was a better way than a phone for this.

"Hey boss…" he said when Hank showed up on the screen.

"Hey Jay… ready to tell me what was it about when we last spoke?"

Jay actually laughed at that "What? You were worried about me?" Voight grunted something that sounded as an uncomfortable confirmative. "Oh"

"Jay…"

"Ok, Ok… There was a fire in the hotel, there was a body… aaand, long story short – I want to help with the investigation, but I would like to have something first… But I have nothing… Any ideas?"

*sigh*"May be you… Well, I don't know. You did mention that you know somebody stationing in Pearl Harbor one day, some military intelligence person." said Hank after a while.

"Ha…" the younger man thought for a second "I do… Thanks Sarge, gotta go…" and he clicked the Skype off. After some searching in his phone he located the number. She picked up after two rings.

"Hello Jay" said the woman on the other side of the line "How can I help you?" he heard smile in her tone.

"Hey Mac. I got a little favor to ask…" and he told her about the fire and body, and all the rest.

*sigh* "You know what… A guy I know from Naval intelligence is the one usually calling favors like this.. But you…" she laughed "Ok. I'll see what I can find"

"Thank you very much, I owe you a beer"

"Oh no my friend… You owe me a dinner"

Of course the "dinner date" was Mac's way of giving him what she managed to gather…

And that is how he got files of all the cases of the vic, and that is how he found a detective that worked most of the cases, too.

He was now sitting in a rental in front of the detective's house. "Oh… Hi" he thought noticing Steve's Silverado driving up to the house "so you came up with that too" he saw Steve and a girl, he also saw at the hotel the day of the fire, walking up to the front door and walk in… "Unlocked door… not good" He got out of the car and the moment he did he saw someone walking from behind the house. Black Tshirt, red cap, sunglasses and slim… But not thin… To him guy looked deadly… "oh..oh.."

He hesitated for a split second and sprinted to the front door.

"Commander!" he yelled in…

"Jay? What are you…" started McGarrett

"No time. Gotta get out, sir." said Jay in a rush.

"Why?"

"I'll explain later." he sniffed "Hurry, please…"

Steve looked at him, wide eyed "he's scared…"

"Body!" he heard Tani "Oh…" now he sniffed too.

"Tani, out!" he yelled and heard her bolt. He did it too…

*whooof*

They felt a rush of heat on their backs…
