Thanks for the reviews.

I will take them into consideration but Petit Ange, I'm sticking to what we already had.

Okay, fasten your seatbelts, because we are finally going to figure out who Number One is.

"Luke Tyler. The fingerprints are from Luke Tyler."

Cullen sighed and closed his eyes.

"God, no."

Zach, Cam and Hodgins stared in awe at Cullen. They didn't understand his reaction.

Cullen ran his hands over his face, took a deep breath and started to explain.

"During Booths first year with the bureau he had to solve a rape case. Susie Tyler had been viciously raped in a car. Her brother Luke, was the one who found her. He took her to the hospital and the case ended up here."

The room was silent. Every one in it knew the importance of the information that Cullen had.

"Booth had a very hard time solving the case. There weren't many clues and Susie was to afraid to talk about it. Booth never really managed to get a good statement out of her."

There was a short silence.

"Nonetheless, he solved the case. But the man still walked."

Zach was curious. He knew it probably wasn't the time for it, but by the time he'd realized that, the word had already left his mouth.

"Why?"

"Because of a technicality. Tyler was furious. He swore to get vengeance."

Cam swallowed before she asked the question.

"On Booth?"

Cullen shook his head.

"No. On his sisters rapist. Booth talked to him and got him so far to give it up."

Hodgins knew that Booth could be very convincing. But he had recently lived the fear and despair of thinking that the woman you love has been raped, so he couldn't really imagine anything that would take that kind of anger away.

"What did he tell him?"

"He told him that he needed to be there for Susie. But..."

Cullens voice stopped.

"But what?"

This isn't the time to beat around the bush.

Cullen looked at Hodgins before he answered.

"Susie wasn't dealing with her rape. A week after the trial, Susie Tyler took her own life."

"How?"

The scientist inside of him was taking over. He feared the answer.

"She took an overdose of painkillers. After that Luke lost it. Susie was all he had."

"What happened?"

Cam knew, but she still needed to hear Cullen say it.

"Luke killed the man responsible for his sisters death and Booth..."

"Booth had to arrest him." Cam added.

"And he did."

I am glad to announce, and you are probably glad to read, that we will have to leave our beloved squints for now. Time to see how B&B are holding up...
