Author's Note: I got the idea for this story from reading spoilers for the upcoming episode "Life Sentence." In the spoiler, Danny and Mac are questioned by IA after confronting a suspect who had attacked the crime lab earlier in the day. I tried to imagine what could cause these two in particular to be involved and this is what I came up with. I hope you like it.

Blown Apart

Crime Lab

Lindsay Monroe Messer entered the Trace Lab putting on her lab coat. She was surprised at how empty it seemed. Normally it was bustling with activity this early in the morning. It's lone occupant, Adam Ross looked up from his microscope and smiled.

"I've never been so glad to see you in my entire life."

Lindsay laughed softly. "Don't let my husband hear you say that. I hear he can be a tad jealous. Why are you still here? Weren't you coming on when I left yesterday?"

Adam rubbed his eyes tiredly. "Pulling a double. All night I've been running trace from a triple homicide. Those two boxes of evidence just came in with a rush order. I haven't even had time for a cup of coffee this morning. It is still morning, isn't it?"

"For a few more hours at least. Why don't you take a break? Mac wouldn't want you collapsing from exhaustion." Lindsay didn't have the heart to tell him he already looked like he was past the point of collapse. Adam shook his head adamantly.

"No way. Those boxes came from Mac's crime scene. If he comes back and they aren't done, he'll have my head. Just look at those boxes; it'll take me hours to finish all that evidence."

One of the boxes Adam was referring to was rather large but the other was only a third of its size. It did promise a rather heavy workload. Glancing from the boxes to Adam's tired expression, Lindsay took pity. "Go; take a break. Grab a cup of coffee and a muffin; whatever. I'll get started processing the smaller box in the meantime. Seriously, you won't do anyone any good if you fall asleep at your microscope."

Adam's face lit up. "I could kiss you. I won't because you're right; Danny is more than a tad jealous and is way scary. But if it weren't for that I'd definitely kiss you right now."

Lindsay was laughing as he left the lab. She crossed over to the table that held the two boxes from Mac's crime scene. She was a little surprised that he'd already been able to send evidence from that scene back to the lab. When Danny had dropped her off at the lab earlier, he was leaving to meet their boss at the scene. Humming to herself, she picked up a knife to break the seal of the smaller box.

Crime Scene

Danny Messer parked the Avalanche behind Mac's and exited the vehicle. He saw his boss kneeling next to the dead body and joined him. "Sorry I'm late. Had to drop Linds off at the lab before I came. Good thing I did 'cause there was this letter waiting for you at reception. It was marked urgent, so I figured I'd deliver it personally."

Rising Mac took the sealed envelope from Danny and opened it. He slid the single piece of paper out with two gloved fingers, always careful to preserve evidence just in case. He read the letter and looked at Danny. Concern etched his features as he turned the note so that Danny could read it. A cold chill ran down the younger CSI's spine as he read the carefully printed words on the page.

My plans for the perfect crime were blown apart by your lab. Time for me to return the favor.

"We need to get back to the lab immediately!"

Crime Lab

Adam had barely made it to the break room when he heard the explosion. The sound seemed to be coming from the Trace Lab where he just left Lindsay. The fire alarm began to blare as everyone started running for the stairs. Worried about his friend, Adam raced back to check on her and just outside the lab when a second, stronger explosion blew him off his feet. Then he heard nothing else.
