Mac, Horatio, and Grissom walked into the New York crime lab and immediately went in search of their teams. They were men on a mission. They were each missing a person from their teams. And they were all willing to do whatever it would take to get them back.

Grissom had just found Warrick and Greg hanging around with Adam, one of the local lab techs, when his cell phone began to chirp from his pocket. He quickly pulled it out and found that he had a message. He called up his voicemail and listened…

"Hey, Grissom, it's Mandy. I pulled some prints off that note you gave me. Got a hit on AFIS. A Richard Carlson. Has an address in New York. Hope that helps. Bye!"

Grissom snapped his phone shut, his mind buzzing. That name…he recognized it…it was Pete's brother. But everyone called him RC. Wait a minute…how did he know that? He shook his head. It was strange how little tidbits of information like that would just suddenly pop into his head. It was a bit disturbing.

He immediately ran to find Mac and Horatio. They finally had a lead. Maybe now they would get some answers. Answers that would help them find their missing friends.

Catherine and Calleigh jumped from their seats at the commotion outside. The two CSIs had been trying to formulate a plan of escape when they heard the slam of a car door. It looked like they were getting a new roommate. But whoever it was, she wasn't going quietly. It sounded like she was putting up quite a fight. Someone suddenly yelped in pain then there was a loud slap. A whimper. Silence.

The sound of the door being unlocked caught their attention. Both ladies turned just as the door opened with an ominous squeal. A mop of dark curly hair suddenly flew into the room and hit the floor, hard. Someone swore as the door slammed shut behind her.

The two immediately ran to her side to help. She looked up at them, disoriented, her eyes rolling around, unable to focus.

"Hey, you okay?" Catherine spoke gently.

"What's your name, sweetie?" Calleigh asked.

"S—Stella," the woman answered, her words slurred.

Calleigh vaguely recognized the name. Horatio had mentioned her after returning from one of his trips to New York.

"Something's wrong with her," Catherine said. "Help me get her onto the bed."

With some effort, Catherine and Calleigh somehow hauled Stella onto the bed where she immediately collapsed, her head lolled to one side.

"I think she's been drugged."

"And I think I know how." Calleigh pointed out a red spot on Stella's arm. A tiny puncture wound was barely visible. "He injected her with something."

"She's still alive though," Catherine said, checking her pulse. "But she won't be for long if he keeps dosing her like that."

Things were starting to look grim for the three female CSIs. One had been beaten and raped, one had been crippled, and the other had been drugged. If they weren't found soon, they weren't sure they would be able to survive much longer.

Stella's eyes fluttered momentarily and in her haze, muttered a single word.

"Mac…"

More determined than ever to find their missing CSIs, Horatio and Grissom, accompanied by Flack, headed for Rick Carlson's place. They had to ring the bell several times before someone opened the door.

"You don't give up easy, do you?" said the sour-faced man in the doorway.

"No," Horatio looked up at him. "We don't."

"Are you Richard Carlson?" Don asked.

"Who wants to know?"

Don immediately revealed his badge. "NYPD. We're actually looking for your brother. You wouldn't happen to know where he is by any chance, would you?"

He started to shake his head. "No, I don't—"

"Today is not a good day to lie to me, man."

"I—I swear, I have no idea—"

"Sure you do." Grissom stepped forward. "You're the one who left me that note, remember? Under no circumstances are you to investigate this. What does that mean exactly?"

He started to close the door. "I'm sorry. I'm kinda busy—"

Horatio kicked the door, hurling it open and hurling him a good distance, too. "Don't ever shut the door when an officer of the law is speaking to you."

He was about to continue arguing, but there was a very angry cop coming into his house. He turned and ran through the house and out the back door—where Mac was waiting for him and quickly slammed him face-first against the back wall, holding him there in an inescapable armlock.

"Now we can make this really simple. You know where our CSIs are and we want them back." He gave the man another slam against the wall. "Your turn."

"I don't know what you're talking about!"

Another slam. "Wrong answer."

A voice behind them ordered, "Let him go, Taylor."

There was a tall, imposing man standing a few feet away, one hand tucked inside his suit jacket.

Everyone froze, but Mac didn't let go.

"Easy now," said the man. "We're on the same side." He pulled a badge from his jacket pocket and showed it to them. "The name's Mike Trellis. I'm his Parole Officer. I've been keeping an eye on him since I heard his brother was sighted."

"Mike Trellis," Mac repeated thoughtfully.

"So, what'd ya find out?" Flack demanded.

"Not much. His brother hasn't come around here, yet. Probably knows you're on to him. Look, some of your people are missing and I want to know what he knows as much as you do. Now, just take it easy and let him go."

There were a couple of steps leading up to the back door. Mac put the man there, keeping an eye on him.

Grissom approached Mike Trellis. "What do you know about our CSIs? Where are they?"

Trellis stepped forward, reaching inside his jacket again. "Now, like I said before—"

"HEY!" Mac grabbed his arm, forcing it skyward.

His hand was holding a gun.

Flack was there in an instant, but Mac already had Trellis in a very painful armhold, and with a skillful move he'd probably learned as a Marine he threw him to the ground. In less than a second, Trellis was looking up into the barrel of his own gun, now in Mac's hand.

Flack smiled and gave a little nod. Having an ex-Marine as cop came in handy sometimes.

"I've had someone pull a gun on me before," Mac told Trellis. "and that's what it looked like."

Horatio caught movement out of the corner of his eye.

Rick Carlson was gone, the door was still flapping open where he'd passed.

"I have something to take care of." Horatio slipped his sunglasses on and took off after him.

Flack strode up to Trellis, now on his stomach, and handcuffed him.

Mac knelt beside him. "And now, Mr. Trellis, you will tell us exactly where our CSIs are."

Ooo…Mac's mad. What happens next? Review to find out!
