Political correctness was all very well, but at what cost to the nation's security? The men on the planes had been recruited from upper-middle-class Saudi families, well educated and for the most part well off. Therefore American security forces manning American borders ought to be looking hard at upper-middle-class, well-educated, well-off men of the Islamic faith of every nationality. Never mind that there were millions of Muslims who did not subscribe to the notion that killing was the way to revenge, redemption, and paradise. Nobody ever hijacked an El Al jet and that was because El Al knew all there was to know about profiling and then some.

We could take lessons, Chisum thought now, and we should. As he had told Khalid nearly two years before, Kallendorf wasn't all wrong.

But Isa's first real piece of bad luck had come in Istanbul. He had learned enough, probably from Bayzani, to know that he'd have to have a duty station on offer when asked. Alaska would have seemed sufficiently remote to be safe. What were the odds, he would think, that he'd find himself riding an elevator with a Coast Guard officer born in Alaska?

Turns out, pretty good odds if he'd had anything but a superficial knowledge of the U.S. Coast Guard, who maintained a very large presence in Alaska, a state with 36,000 miles of coastline if you included all the islands, peninsulas, and archipelagoes.

That was not the real question, however.

The real question was, what was Isa doing at an IMO conference on marine safety in the first place?

There were two possible answers to that question.

One, he was there to learn what measures the international maritime community was putting in place to ensure the safety of vessels and crews working the high seas, for the purpose of confounding those measures and launching an attack against pick a target.

Two, and the answer Chisum considered far more probable, Isa was there to meet someone. Someone already inside the maritime community. Someone with a solid working knowledge of the shipping industry.

Or, or perhaps including, a working knowledge of ports. Western ports. Busy ports. Vulnerable ports.

But then, they were all vulnerable. Less than three percent of containers coming into U.S. ports were examined for contraband. Anybody could tuck anything inside of a container, stick it on a Horizon Lines ship, and feel pretty secure that it would never be spotted.

On the other side of his door he could hear the phone still ringing, though less frequently than before, and Melanie's voice still desolate at her inability to oblige any of the callers. She was really very good. She came in with another sheaf of phone messages. He looked at the clock. "Hey, it's after five. Go on home, Melanie."

"I can stay, Mr. Chisum. You could use the help."

"You have to have something better to do than babysit me, Melanie."

She smiled. She had a dimple in her right cheek. Her skin was like ivory. He recognized the triteness of the observation at about the same time he realized he'd been staring. He could feel the color creep up over his face, and he said gruffly, "I appreciate it, Melanie, thank you."

And again he watched her walk out of his office. Rumor had it that she'd been seen outside the office in company with Kallendorf. He hoped it wasn't true, and not just because it would mean the director had a spy too close to Patrick for comfort. He liked Melanie. He liked her a lot. She had thus far proved not only decorative but capable and efficient as well. True, he also liked the thought of her naked and stretched out on a bed, but he tried not to dwell on that. It was always a mistake to dip your pen in the company ink. Particularly this company.

He swiveled back to his computer and got online. The IMO's web site displayed an impressively far-reaching organization, with at a rough count over 170 member nations, including ones like Bolivia, Switzerland, and Mongolia, which so far as he could recall without looking at an atlas were landlocked. The U.S. Coast Guard was the United States ' representative at the IMO. He wondered who other nations sent. Be worth finding out. He made a note.

Then there were the government and non-government organizations affiliated with the IMO, some of which might prove productive of investigation, like the Arab Federation of Shipping, the Organization of Arab Petroleum Exporting Countries, the International Association of Ports and Harbors. This last looked interesting so he pulled it up, and found links to countries with links to various of their ports. He clicked on Ireland in memory of Josie Ryan and on the Shannon page somewhat to his dismay found all the information he could wish for about the port, including maximum vessel dimensions and a scale map showing seven separate ship-berthing facilities.

He sampled some of the other port pages, and while some web sites were better than others they were all very informative.

He swiveled back to the window and reassumed the position.

On ports at least there was all the information Isa could wish for on the Internet if he were planning an attack against one. He would have no need to attend a conference on maritime safety to learn more.

No, he would attend a conference on marine safety to meet someone there. Patrick was now certain of it. Someone who had either information he needed, or expertise. Or both.

But Patrick wasn't going to catch him to ask him, at least not today. Maybe tomorrow, or the day after that, but that was then. He'd put everyone on the alert. All he could do now, maddening as it was, was sit back and wait for Isa to be spotted.

Maybe, he thought, just maybe he was looking at this from the wrong direction. Isa was in the wind. Someone might stumble across his path again, but the odds weren't in their favor. They'd been incredibly lucky in the two contacts they'd had, both by conscientious, practicing professionals, but it was fatal to depend on lightning striking that way a third time.

And besides, Patrick was tired of being a step and a half behind this guy. It was time to do a little backtracking, find out what made the guy tick so they'd have some idea of what he might do next, and where.

Chisum turned back to his desk and picked up the phone. This time he got the nation code right and Hugh Rincon's voice mail came on. He realized that it was after ten o'clock in London. "This is Patrick Chisum again. Who else attended that conference in Istanbul? I want a breakdown by names, professional organizations, and nationalities."

He hung up and frowned at the clock on his desk. The minute hand swept inexorably around, counting down the seconds, the minutes, the hours.

Like he needed reminding.

HAITI, DECEMBER 2007

It took him a pitifully short time to find what he was looking for in Haiti, which cost him in U.S. dollars the equivalent of a used car, which he found even more pitiful. While he was conducting his business he stayed in a modest room at a resort hotel, renting a girl for the weekend so as to maintain his cover as a car salesman on holiday. She was a straightforward businesswoman, with a refreshing lack of curiosity even that first night when he gently refused her sexual services and insisted she sleep in the second bed. "Arm candy only, then," she said, as if it wasn't an unusual request, and didn't offer a discount. Time paid for was time paid for. On a professional basis, he had to respect that. She insisted on half up front. He respected that, too.

After he concluded his business, he maintained his cover by spending the weekend at the hotel lounging poolside with his paid companion, taking an hour off to find a cybercafé and check in. Yussuf and Yaqub were in Canada, one in Toronto and the other in Vancouver. They reported all cell members accounted for and settling in to their various temporary lives.
