I spent most of the drive out from Denver talking about that night at the Pints Of. Not that anything important had happened. It was just drinks with my brother at the cop bar.

And it was the last good time between us, before Theresa Lofton came up. That memory put me back in the aquarium.

But during the moments that reality was able to punch through the glass and into my heart, I was seized by a feeling of failure and grief. It was the first real tearing of the soul I had experienced in my thirty-four years. That included the death of my sister. I was too young then to properly grieve for Sarah or even to understand the pain of a life unfulfilled. I grieved now because I had not even known Sean was so close to the edge. He was Lite beer while all the other cops I knew were whiskey on the rocks.

Of course, I also recognized how self-pitying this kind of grief was. The truth was that for a long time we hadn't listened much to each other. We had taken different paths.

And each time I acknowledged this truth the cycle of my grief would begin again.

My brother once told me the theory of the limit. He said every homicide cop had a limit but the limit was unknown until it was reached. He was talking about dead bodies.

Sean believed that there were just so many that a cop could look at. It was a different number for every person. Some hit it early. Some put in twenty in homicide and never got close. But there was a number. And when it came up, that was it. You transferred to records, you turned in your badge, you did something. Because you just couldn't look at another one. And if you did, if you exceeded your limit, well, then you were in trouble. You might end up sucking down a bullet. That's what Sean said.

I realized that the other one, Ray St. Louis, had said something to me.

He turned around in his seat to look back at me. He was much larger than Wexler. Even in the dim light of the car I could make out the rough texture of his pockmarked face. I didn't know him but I'd heard him referred to by other cops and I knew they called him Big Dog. I had thought that he and Wexler made the perfect Mutt and Jeff team when I first saw them waiting for me in the lobby at the Rocky. it was like they had stepped out of a late-night movie. Long, dark overcoats, hats. The whole scene should have been in black and white.

"You hear me, Jack. We'll break it to her. That's our job, but we'd just like you to be there to sort of help us out, maybe stay with her if it gets rough. You know, if she needs to be with somebody. Okay?"
