He thought about trying to pin down which version of her story was the real one, but this just didn't seem like the time or place to get into an irresolvable yes-you-said-it, no-I-didn't discussion.

"Well," he said, "whatever the reason for why you were there, thanks again for saving my life."

"The alternative would have made a hell of a mess of the interior in that snazzy Buick of yours."

Earlier in the evening, as she was working on his tie, Gabe would have offered his ranch for them to be sitting together at four in the morning on a bench behind the Watergate, overlooking the silent, ebony Potomac. Yet here he was in just that situation, distracted, edgy, and totally ill at ease.

"Tell your boss that your secret is safe with me."

"I'm not sure that will do the trick, but I'll try."

"I always wondered why they called it the Secret Service when those agents in their dark suits and shades made no effort whatsoever to be secret."

"They're meant to be seen and recognized. A lot of us aren't."

"And there are Secret Service offices outside of D.C.?"

"There are field offices all over. We do investigational stuff and also prepare for any presidential or major diplomatic visit."

"And our good friend the admiral doesn't know he's got a Secret Service agent working for him?" Gabe asked.

"Almost no one knows."

"Treat Griswold?"

"Nope. I report only to one man-the head of internal affairs."

"Internal affairs?"

"Gabe, I really can't tell you any more right now. First thing in the morning I'm going to have to report to my boss that I've blown my cover."

The hour caught up with Gabe, and he tried unsuccessfully to stifle a yawn.

"Listen," Alison said. "Why don't you go on in. I can do all my explaining sometime later. I'll get this bullet to the lab and arrange for your car to be fixed. Just leave it on the street where you parked it. It'll be taken away within the hour, and it won't take more than a day to be good as new."

"Better be. It's on loan from the First Father."

"I know."

"Of course. Everybody here knows everything, or at least tries to. So, what are you going to tell your boss?"

"The truth," she answered matter-of-factly.

"Ach, truth. Such a word. I would have never thought it was one of them words that meant different things in different parts of the country, like soda and pop or pancakes and flapjacks. Is that what you told me back in the office about how you came to be at the White House? The truth?"

"I'm sorry. You have every right to be irritated, but I was just doing what I had been ordered to do."

"And what should I tell my boss?" he asked.

"That's up to you, but I'm not sure what's to be gained."

"Secret Service protection?"

"Depends on how badly cramped you want to be."

Gabe again pawed at his eyes. He felt worn down by the events surrounding the president and utterly bewildered by this woman and by the attempt on his life, but he was also strangely unwilling to head up to his apartment. Below them, the surface of the river had begun subtly reflecting the first changes of the new day. Gabe found himself absurdly wondering which dignitary had gotten the bull's head on President Calvyn Berriman's Botswana flag cake. Maybe it was Lily Sexton.

"So tell me," he asked finally, "how did a nurse end up with a badge and a gun and a desk job in San Antonio?"

"You sure you don't want to do this later in the-"

"No, no. I'm really interested. Besides, I feel a second wind coming on."

"I can't tell if you're being facetious or not."

"Defensive might be a better word. Or maybe I'm just testy. I was busy taking care of the president's gastroenteritis and migraine, and missed out on dessert."

Gastroenteritis and migraine. The untruth rolled out effortlessly. Perhaps he had a future in D.C. after all.

"Well, okay," she said with a shrug. "The story I told you is pretty close to what is. I was born in Louisiana and raised in New York-Queens. My dad, I think I told you about him, is… was, I mean, part Creole, part southern cracker-very handsome, very charming, rarely employed for long. My mom is part Japanese, part other things. She's a nurse. Still works in a nursing home. I became a nurse because of her, and got my master's."

"When we first met, I tried to piece together your background from your looks."

"I doubt you would have come close."

"I didn't. But it's a combination that works pretty well."

"Thanks. More?"

"If you want?"

"Let's see, then. A brief fling at marriage took me to L.A., where I worked in a surgical ICU. Like many hospitals, it was more or less ruled by the surgeons-one group in particular, busy beyond imagination, wealthy, and arrogant, all male, all well connected. The Cognac and Cuban Cigar Club, we used to call them-the Four Cs. The problem was that while most of them were top-notch and maybe deserving of the big bucks, a few of them weren't that good."

"Go on."

"Well, I won't go into the details, but there was a death in the unit. An order that should never have been given, written by a surgeon who was well aware of the patient's history and should have known better. He was one of the founding partners of the group, and drank too much. He also had neglected to inform the nurses about past events with their patient. Then there was a ridiculous delay in his getting in touch with the unit after he was paged, followed by a botched attempt to open the poor woman up right there in the ICU."

"Sounds gruesome."

"Even more gruesome was the way the group railroaded blame for everything onto one of the nurses. It was done with the ruthlessness and efficiency of a commando unit. Sheets disappeared from the patient's chart; doctors came forth with blatant lies. Unfortunately for her, they picked on a nurse who was going through a bitter divorce and was on a bunch of meds for depression, and who wasn't really that clinically strong anyhow. Janie got suspended from work, and then she overdosed. She didn't die, but I think sometimes she wished she had. Eventually, her ex got their kids and she moved away."

"Were you two close?"

"Not that close, but we considered one another friends. I couldn't stand to see what they had done to her, and I was on duty when all this happened, so I decided to blow the whistle on the surgeon and those who covered up for him."

"Uh-oh."

"Uh-oh is right. They went after me the same way they went after her. It was a total mismatch. Evidence began to surface that suggested I had assisted Janie in diverting drugs and was just trying to defend my partner in crime. I began getting weird phone calls. A year before, I had broken off a three-year relationship with a man who decided that, despite what he and I had agreed upon all along, he didn't want kids. A new guy I had just started dating, who seemed very promising, without any real explanation suddenly wanted nothing to do with me. My record at work had been spotless, but out of the blue several groundless incident reports were filed against me by supervisors who had connections to the surgical group. It seemed as if the doctors were actually enjoying the challenge of systematically dismantling my life."

Gabe studied her face. Even through the gloom, he could see the tension and hurt. They seemed real. Then he reminded himself that he had already bought her story once tonight. These people were good at manipulating the truth-very good. He turned back to the river. She was so attractive to him that it was hard to hang on to the notion that she might not be someone he could trust. At the same time, it was odd to think that while he was sitting there, listening to her this way, he was managing to avoid the issue of whether or not he should be instituting measures to remove the President of the United States from office.
