AN: Thanks to my fellow readers and reviewers. Letting you know, I will keep this story posted here in this fandom. Although it is a cross-over, this story will have a heavier emphasis on "Hawaii Five-O" and therefore it is not necessary to be familiar with "The Streets Of San Francisco".

Chapter 2

General Hospital, Potrero Avenue, San Francisco, 1972

"How is he doctor?" Mike Stone questioned the doctor who met him in the bustling corridor of General Hospital.

"He has a concussion and a deep gash to his head. It looks like he received two heavy blows to the head; one from the side and one from behind. From the damage, someone may have used a metal pipe with a jagged edge or even a rock. It's too early to tell the extent of his injuries as far as brain trauma is concerned." The doctor explained the diagnoses of his patient to the senior Lieutenant.

"Can we see him?" Stone asked with genuine concern in his voice.

"He's still unconscious." The doctor shook his head then added, "I'll call you when he regains consciousness, Lieutenant."

"Okay, thanks Doc." Stone nodded as the doctor excused himself to be intercepted by a nurse.

"Hey Mike!" The voice of Steve Keller spun the grey haired cop around as he faced the young Inspector who had returned from the front desk to make a telephone call.

"Did Tanner get a registration on that 22. yet?"

"Yeah. It's registered to a Danny Williams from Honolulu, Hawaii." Steve read the details out from his note book.

"Hawaii?" Mike's puzzled remark brought a smile to Steve's face for a flicker of a moment before the young man continued in a more serious tone.

"Yeah, that's not even half of it. He's a cop."

"Undercover?" Realization dawned on Mike's face as the likelihood of such an operation was more probable than the theory of a crooked cop in their midst, particularly from another state.

"Yeah. Apparently Olsen knew about it but Washington's strict orders were to keep a tight lid on it. Also, Sergeant Haseejian got a call from a detective Steve McGarrett of Hawaii Five-O, a special unit in Honolulu. His detective is reported missing. His name is Danny Williams, age 32 and he matches the description of the guy we found. He was supposed to report in last night last but never did." Steve continued.

"At least we now know who the guy is. It's not the first time the captain's left us in the dark. Is the FBI involved?" Mike lowered his voice and pulled Steve over to the side, away from two curious nurses passing by.

"I don't know, Mike. I thought we were dealing with gang related homicide? Why would the FBI be involved?"

"No, you're probably right. Why would they? I guess I just get a little uneasy when I'm left in the dark, that's all. Listen, I'm going to head back to the office. Do me a favour will you buddy boy? Stay here a while in case our friend wakes up. And contact this McGarrett. He'll want to know what's become of his detective." Mike tried to shake off the uneasy feeling in his gut that told him something big was going down as he gave his instructions.

"Sure." Keller closed his notebook and made his way to the telephone to make the call as Mike hurried towards the elevators.

Hawaii Five-O Head Quarters, Iolani Palace, Honolulu, 1972

Steve stood, lost in thought, facing the lanai as he downed his mug of black coffee, which had gotten cold. Where are you Danno? The phone rang suddenly and broke through his reverie. In one fluid motion, Steve turned away from the window and launched himself at his desk, grabbing the telephone receiver. "McGarrett!"

"Steve, there's an inspector Keller from SFPD on line one for you. He says it's urgent." Jenny relayed through the intercom.

"Thanks love, put him through."

"McGarrett speaking."

"Mr McGarrett, I'm Inspector Steve Keller from the San Francisco Police Department. I'm returning your call concerning the whereabouts of detective Danny Williams. He was brought into General Hospital an hour ago." The young inspector paused to allow the detective on the other end of the line time to register the news.

"The hospital? What happened?" McGarrett's frown deepened at the revelation that Dan was injured.

"We don't know all the details but he sustained some pretty bad injuries to his head. He hasn't regained consciousness since we found him in an alley." Keller continued, noting the concern in the detective's voice on the other line.

"How bad?" McGarrett felt his voice catch as his throat became too parched and constricted to speak clearly.

"I don't know, sir." Keller wished he could give more information but it was all he had.

"What do you mean you don't know? My detective is lying in the hospital and you can't tell me his condition?" McGarrett barked into the mouth piece, irritated that the inspector couldn't tell him that Dan was going to be alright and worried that Dan could be seriously hurt.

"I'm sorry, Mr McGarrett. I'll call you as soon as I hear anything." Keller didn't care for the detective's tone but he forced himself to keep his composure and put himself in the McGarrett's shoes.

"Don't bother. I'll be on the next flight." McGarrett hung up before Keller could say anymore.

Hold on Danno.
