For the right woman? I'd like to think I'd do just about anything.

I actually do have a motto,” said Heat. “It’s ‘Never forget who you work for.'" And as she voiced the words, Nikki felt a creeping unease. It wasn’t exactly shame, but it was close. For the first time it sounded hollow. Fake. Why? She examined herself, trying to see what was different. The stress, that was new. And when she looked at that, she recognized that the hardest part of her day lately was working to avoid confrontation with Captain Montrose. That’s when it came to her. At that moment, sitting nearly naked in Rook’s living room, playing some silly nineteenth-century parlor game, she came to an unexpected insight. At that moment Nikki woke up and saw with great clarity who she had become - and who she had stopped being. Without noticing it, Heat had begun seeing herself as working for her captain and had lost sight of her guiding principle, that she worked for the victim.

It pained her that a few hundred words in an also-ran newspaper could get her kicked out. That damned article. And Rook. Her sharpest agony. She had invested in this guy. Waited for this guy. Felt something for this guy that went beyond the bedroom ... or wherever else they took each other. Nikki did not give herself easily to a man, and this betrayal by Rook was why. Heat reflected on her answer at the oral boards about her greatest flaw and admitted her reply was a mask. Yes, her identification with her job was total. But her greatest flaw wasn’t overinvestment in her career. It was her reticence to be vulnerable. Unarmed as she was-literally-she had been emotionally so with Rook. That was the gut shot that had blown clean through her soul.

It's so funny castle, you know, at first I loved that he was so busy. It just, it just gave me the opportunity to keep one foot out the door just on case. But with one foot out the door, it's hard to know where you stand. And even if I did what does it mean?

It was always the same for her when she arrived to meet the body. After she unbuckled her seat belt, after she pulled a stick pen from the rubber band on the sun visor, after her long fingers brushed her hip to feel the comfort of her service piece, what she always did was pause. Not long. Just the length of a slow deep breath. That's all it took for her to remember the one thing she will never forget. Another body waited. She drew the breath. And when she could feel the raw edges of the hole that had been blown in her life, Detective Nikki Heat was ready. She opened the car door and went to work. . . Heat could have made it easier on herself by parking closer, but this was another of her rituals: the walk-up. Every crime scene was a flavor of chaos, and these two hundred feet afforded the detective her only chance to fill the clean slate with her own impressions.

I want to know how the hell you managed to locate that hideout using the damn public library.
