"Did you get it?" she asked immediately when she walked into Cam's room.

"It's a internal government control sample, so it's taking a while to come through." She replied.

"Right." Brennan said but the second she heard government she thought that Booth had probably just given some friend a lift home.

"I'm going to get some coffee." Cam said leaving the room. Brennan heard someone in the main lab and went to see who it was. When she got there she found a man in a courier's uniform.

"Hi… am I'm looking for a Dr Brennan. Do you now him?" he asked. Brennan crossed her arms and tapped her foot.

"I am him!" The man nearly choked.

"Oh my… I'm so sorry… I'm new and I didn't know." He just handed her the package and scuttled out of the room. Brennan knew what would be written on it before she looked. But this one was different. It was thicker then the others. With shaking hands she opened it. She found two more inside. Taking the thinner of the two she opened it, and a note fell out. Picking it up Brennan read it out loud

"He won't be there to take the blast this time…" looking at the picture she dropped the lot.

"Cam don't…"

So any guesses as to who it is?? I know it's not that hard!! (",)
