A/N: I promised one more before the weekend, so here it is.

Chapter 4

The rest of the party had passed without incident. It took Jane and Maura a little while to put Doyle out of their minds, but when they did, they had been able to enjoy the rest of the evening.

Maura's parents really had organized a lovely event for them, and they were very grateful for the time and effort they had put into it. Especially Maura was overjoyed with the time she had been able to spend with both her mother and her father, for the moment, her run in with Doyle all but forgotten. Unfortunately her parents wouldn't be able to stay in Boston for much longer. Alexander had a speaking engagement in New York on Monday, and a few days later they were both traveling back to London for the opening of Constance's new art gallery.

They had a leisurely brunch together on Sunday afternoon, after which a town car came to pick Mr. and Mrs. Isles up, to bring them to the airport. Maura had been somewhat in a funk ever since.

Jane had tried to cheer her up, but her attempts had so far been unsuccessful, so she decided just to give her fiancee some space until later.

The detective was lying stretched out on the couch. Watching TV with one eye, while keeping the other on Maura, who was sitting in a chair with a book on her lap. Jane could tell she wasn't actually reading, since she hadn't changed the page in at least thirty minutes.

When the blonde let out a deep sigh, for the third time in as many minutes, Jane turned the TV off, and walked over to Maura. The detective kneeled down in front of the moping woman, hands slowly rubbing her thighs, to get her attention. "What's wrong, Maur?" she quietly asked.

Distracted hazel eyes met her own.

"Are you upset because your parents left?" Jane tried again, kind of asking the obvious, but hoping it would get the blonde to open up a bit.

To her surprise, Maura shook her head.

"No? Then what's bothering you, babe? Maybe I can help." Jane gently squeezed the doctor's legs, giving her some encouragement.

Maura worried her bottom lip, "it's just something my…Paddy told me."

The brunette fought to keep her expression neutral, she swallowed, but stayed silent, waiting for Maura to continue.

Maura closed the book that was still laying on her lap and put it on the side table, before looking back at Jane. "He said he would tell me who my mother is, I told him I already have a mother and a father; that I didn't need his information, or him."

"What did he say?" Jane asked, taking Maura's hands gently into her own.

"Not much. He said, he would tell me when I was ready. Then he congratulated me on our engagement and disappeared," she shook her head.

Jane knew how badly Maura wanted to know where she came from, and who her biological mother was, or is. "But now you wish he told you?" she asked, already anticipating the answer.

The doctor looked at a spot on the chair's armrest for a long time, organizing her thoughts, trying to formulate her response, "I do. It probably doesn't make any sense, but I want to know who she is, Jane."

"It makes sense, Maur. You want to know your roots, I get it." Jane put her hands on Maura's shoulders, "I just wish Doyle wouldn't play with you like that, he should've told you a long time ago."

Maura nodded, wishing the same thing. She leaned forward and pulled the brunette close against her. Even though she was still confused and a little upset, she was happy in knowing, that no matter what, she would always have Jane.

"Hey," she suddenly said, realizing something. "Whatever is going on with the Whistler Factory case?"

Jane reluctantly pushed herself away from Maura and got up from her seated position on the floor. "We found something," she said, then proceeded to fill the doctor in, on what they had discovered the day before.

The next day, they were back at work. Frost, Korsak, and Maura were sitting in the squad room, trying to convince a very agitated brunette detective, that the plan they had come up with was their best option.

"No," Jane protested, "we're not going to use Maura as bait. This is a killer we're talking about, it's too dangerous."

"We can take precautions," Frost tried to convince Jane, "she can wear a wire, so we'll know what's going on at all times. We'll be right there."

Korsak, who would have the final say, directed his attention to Maura. "What do you think, Dr. Isles?"

"He's already tried to kill me once, I'd rather do something, than wait for him to try again when we least expect it." The doctor was actually oddly thrilled she might have the opportunity to do this, however she thought it best to hide her enthusiasm for the moment, knowing it would not go over well with Jane at all.

The older detective put his hand on Jane's shoulder, who instantly shrugged it off, "I'm sorry, Jane. But I think flushing this guy out, instead of waiting for him to strike again, is our best bet."

Jane was grinding her teeth, her lips pulled in a firm line. She glared first at Korsak, then Frost, and finally at Maura. With the decision now made, and knowing there was nothing more she could do; she briskly left the room without saying another word.

About thirty minutes later, Frost found her downstairs in the gym, pounding on a dummy, like her life depended on it. Her body soaked in sweat from the vigorous work out.

He stepped into his partner's eyesight, which made her stop. She was bent over, breathing hard, trying to catch her breath.

"Everything is going to be fine, Jane." Frost finally said, trying to reassure her. "We'll keep Maura safe."

The brunette gave the dummy another hard punch, "I have a bad feeling about this, Frost. Something is off."

"If you have any other ideas, to catch this guy. I'll go with you to Korsak, and we'll do it your way."

Jane glanced at him, he knew as well as she did, that she didn't have any other plans, not yet anyway; yet she appreciated the intent of the gesture. She could always count on Barry to have her back, and she had his; they made a good team.

"I got nothing," she finally admitted.

"It's going to be okay," he said, trying again to reassure her.

"We'll see," was all she said. Maybe Frost was right, and she was just worrying too much. How could she not; the attempt on Maura's life and her subsequent meeting with Paddy Doyle, did have an impact on her thinking. "Fine, what time are we doing this?"

"Two hours," Frost replied.

"Okay, I'll meet you guys upstairs in thirty minutes."

"Going to take a few more minutes with your 'friend' here?" Frost joked.

She briefly laughed, then turned serious again, directing her attention back to the dummy. Giving it a hard kick for good measure.

As agreed upon, two hours later, they were setting up at the burned down warehouse. Frost, Korsak and Frankie were going over some final details outside, while Jane was helping Maura put on the wire under her clothes.

The doctor was way too excited to be doing this, and Jane was worried. She was only listening with half an ear, while Maura was going on about how this was her first undercover assignment.

"This microphone doesn't make me look like I have three breasts, does it?" Maura said, pulling Jane into the conversation.

They bantered back and forth for a few moments, Maura getting more and more animated.

When Korsak told them, it was time to go, the doctor actually clapped her hands, and jumped up and down for a few seconds. Jane realized it was time to instill the severity of the situation once again to her fiancee.

"Maur, listen to me. This is serious. Someone is trying to kill you." Jane's hands took a firm hold of Maura's biceps.

The doctor actually looked a little offended, "you don't have to tell me that, I was there when he nearly drove me over."

"We're only letting you do this, because we're hoping that whoever this guy is, he's desperate enough to follow you into that warehouse, and try again." Jane took a deep breath, "But we're going to be ready this time, okay?"

Maura still looked way too excited, "I'm ready," she said, with a big smile. "Oh wait, what do you guys say to each other, right before you pull the string."

Jane briefly closed her eyes, "it's called a sting, Maura. And we say, don't get made."

"Oh, I like that. Don't get made." The doctor said, moving her head from side to side, trying to sound all tough, but when Jane didn't smile back at her, she grabbed onto her arms as well.

For a moment, Jane ignored the fact, that both Korsak and Frankie would be able to hear every word she said. "I love you. I'm going to keep you safe, okay," she whispered, then leaned in to capture Maura's lips in a short but sweet kiss.

Maura, a little surprised by the public display of affection, but not complaining, looked intently into Jane's eyes. "Don't look so worried, what could go wrong," she said, trying to relief the woman's anxiety.

The detective didn't even want to respond to that. She knew all too well the things that could go wrong during an undercover operation.

A/N2: This was the last of the build up chapters before the warehouse events.

I am a little worried about what the reactions will be once I post the next chapter, but...I can't change what I have planned. You'll either like it or you won't. All I can do is write to the best of my ability, and promise you I know what I am doing. That, and remind you that my stories will always have a happy ending.

With that out of the way. What did you think of this one?
