Author's note: I forgot mention that this story is set somewhere during season 4 or 5 and Greggie is still lab rat.

Thank you guys for wonderful reviews. I was very touched. Thank you.

Nick and Warrick were coming back to the lab with the trunk of their car full of evidence. When they reached the parking lot, they saw a lot of people there. They stopped near the crowd and went find out what happened. Both recognized the LVPD employees. That had only one reason. Evacuation. They both remembered when this last happened. They came near the group of people in blue coats.

"What's up?" Nick. asked "I hope not another explosion."

"No. But I'm not sure if this is better." Archie answered. "The body from reception had some virus. Whole building's closed. Catherine, Grissom, Greg and doctor Robbins are inside in quarantine and nobody can go there."

"Quarantine?" Nick couldn't believe it and looked at Warrick. But he was standing with his back at the group and he dialed his phone.

Second later, Catherine's mobile rang. She looked at caller ID, turned on the speaker and put the phone on the table to let the others hear the conversation.

"How you four doing there?" Warrick's voice was heard from the phone.

"Three. Al had to stay in autopsy room." Grissom answered his question.

"I don't envy him . What happened, anyway?"

"Doc didn't like the morning DB's lungs." Catherine said this time.

"I heard something about virus."

"Yeah. Greg said that it's legio...ehm?" she looked at Greg, who was sitting in an armchair, starring at nothing. He looked back at her and sighed.

"Legonella pneumophola. It has two forms. One is the Pontiac fever, like Pontiac in Michigan. Incubation period is around 36 hours and it looks like bad flu with fever. It lasts two to five days and cures itself without medication. Another form is legionelosis, or legionnaire fever. Symptoms appear after two to ten days. It's lung infection but it affects also liver, kidneys, brain and digestion. Who has it has fever, doesn't react usual antibiotics, is confused, motory's affected. Quarter of patients ends up in ICU. Treatment is difficult, because it can be easily replaced by pneumonia. Antibiotics such as erythromycin, ryphampicin or tetracyclin help, but even those work until third day. And if doctor don't recognized it till fourth day, it's too late for treatment and many patients die seventh day. Our dead guy had obviously that worse form." Greg said impassively.

"Which doesn't mean that someone caught it." Grissom tried to encourage him.

"For how long you're locked in there?" Warrick asked.

"Two days, three maximum." Catherine answered .

"And what can we do?" Warrick wanted to help them somehow , because those people were they were his friends and they were in peril .

"Try to find out who the dead one was. And how he got infected." said Grissom.

"OK. Hold on there, guys." said Warrick and hanged up.

"Have you ever heard about legionnaire fever?" Warrick asked Nick.

"Just a bit. How can we help?" he answered.

"We can try to state victim's ID."

"I could help you with that." said Jacqui behind them. "Before we were rushed out I found a match. I wrote down a name but I didn't have time for the address." she showed them the black letters on her hand.

"Jacqui, you're the best." said Nick cheerfully. She just smiled.

"I will remind you that." She looked at him .

"Samuel Darpano" read Warrick loud. "Okay, we got a name. How we find out who he was?"

"I have no idea."

"We should let Sara know. I'll tell you what Greg said about the disease, on the way." Warrick motioned to the car.

Grissom sat at the table, doing paper-work necessary for closing the lab, when Catherine came to him.

"What's wrong with him?" she whispered and pointed behind her shoulder to Greg. Grissom looked at him. Since Greg sat in the armchair he didn't move. He answered her silently.

"This virus is treated in biohazard suits in secured labs. It transfers easily. Especially when you're in contact with blood. And he knows it very well."

"You mean we really could have gotten infected?" Catherine asked. She was a little scared. Even after Greg's speech she didn't believe the fact their situation was serious. But Grissom's words assured her that they really were in a big trouble.

"I don't think so. We almost haven't touched victim's clothing and if we did , we had gloves. On the top, the blood was dry and soaked into cloth."

"And what if it was fresh? Just a little , invisible drop of fresh blood that we touched …?" Catherine asked . Grissom knew, what she was thinking about.

"I don't believe, that anyone among us is in the tinniest danger." he answered, looking right into her eyes. Catherine nodded and went to pour herself some coffee. Grissom watched both of his colleagues for awhile. Greg finally moved and joined Catherine. She smiled at him and said something Grissom didn't hear. She handed him a cup and went to call Lindsey. She had to explain to her daughter why she won't be home for a couple days. Grissom again thought about what he just said. He wasn't a liar, but his last sentence wasn't quite the truth.

Nick called Sara while Warrick was driving. It rang three times before she answered.

"Hallo?" Sara said neutrally.

"Hey, it's me. You sitting?" Nick tried to prepare her for a bad news. Sara understood and sat down.

"Yeah. Why?" she asked carefully. Nick told her what happened and what Warrick learned when he called Catherine.

"That doesn't sound good." she said after thinking at the thing she heard .

"Let's hope it's gonna be ok. We need to think up how to find out as much as we can about that guy. Do you know the bistro opposite the airport?"

"Sure."

"Great. We'll be there." Nick hang up.

A few minutes later Sara was sitting in her dark-green car and tried not to drive too fast. She still was thinking about the call she just had. She imagined what could happen in the next three days. She shook her head to get those thoughts out of her mind and tried to concentrate on driving. She was at the place of the meeting ,in front of the bistro, in fifteen minutes and was very lucky she didn't met any cop on the way. She rushed inside. Nick and Warrick were sitting at a big table by the wall. Except for them, there were four people, who probably came for a late lunch.

"That was fast." Warrick spoke and moved to the chair by the wall to let her sit. Sara ignored his comment.

"I got one idea on my way. According to you two, Jacqui ran out pretty fast. Maybe she didn't turn off the database." she said instead.

"I didn't thought about this." Nick replied pulling out his phone and calling Grissom.

"I'll get that!" Greg jumped up from his chair. Finally he was able to do something. He ran into the fingerprint lab. In the first moment, he was very disappointed when he didn't see the standard form with photo on the computer monitor. Then, he realized that what he's looking at is screensaver with the LVPD logo. He smiled a little and moved the mouse. Presently, the screen changed and Greg printed the information. After that, he returned to Catherine and Grissom.

"I have something. That Mr. Darpano worked as security in Pharmaceutics Company. He was fired a week ago because of..." he read the paper that was in his hands again. "...repeated breaking of work discipline. And you know what? Director of the company picked out of the company account sixty thousand dollars."
