"You been out at the station?"
"I was the man who found them. Rather, I was the first man on the scene after the attack. Along with my section chief, Tim Houston."
"You fly your own plane?"
"Yes. Not this time, though. That section of the Brooks Range is like the mountains on the moon. Helicopter. We've been making a continuous check on the pump stations and the remote gate valves since this damned threat came through, and we'd stayed at Station Five last night. We were just approaching Four, a mile away, I'd reckon, when we saw this damned great explosion."
"Saw it?"
"You know, oil smoke and flames. You mean, did we hear anything? You never do in a helicopter. You don't have to ― not when you see the roof take off into the air. So we put down and got out, me with a rifle, Tim with two pistols. Wasting our time. The bastards had gone. Being oilmen yourselves, you'll know it requires quite a group of men and a complex of buildings to provide the care and maintenance for a couple of thirteen-thousand-five-hundred-horse-power aircraft-type turbines, not to mention all the monitoring and communications they have to handle.
"It was the pump room itself that was on fire, not too badly but badly enough for Tim and me not to go inside without fire extinguishers. We'd just started looking when we heard shouting come from a store room. It was locked, naturally, but the key had been left in the lock. Poulson ― he's the boss ― came running out with his men. They had the extinguishers located and the fire out in three minutes. But it was too late for the two engineers inside ― they'd come down the previous day from Prudhoe Bay to do a routine maintenance job on one of the turbines."
"They were dead?"
"Very." Bronowski's face registered no emotion. "They were brothers. Fine boys. Friends of mine… and Tim's."
"No possibility of accidental death? From the effects of the explosion?"
"Explosions don't shoot you. They were pretty badly charred, but charring doesn't hide a bullet wound between the eyes."
"You searched the area?"
"Certainly. Conditions weren't ideal ― it was dark, with a little snow falling. I thought I saw helicopter ski marks on a wind-blown stretch of rock. The others weren't so sure. On the remote off-chance, I contacted Anchorage and asked them to alert every public and private airport and strip in the state. Also to have radio and TV stations ask the public to report hearing or sighting a helicopter in an unusual place. I haven't but one hope in ten thousand that the request will bring any results."
He grimaced. "Most people never realize how huge this state is. It's bigger than half of Western Europe, but it's got a population of just over three hundred thousand, which is to say it's virtually uninhabited. Again, helicopters are an accepted fact of life in Alaska, and people pay no more attention to them than you would to a car in Texas. Third, we've still only got about three good hours of light, and the idea of carrying out an air search is laughable ― anyway, we'd require fifty times the number of planes we have, and even then it would be sheer luck to find them.
"But, for the record, we did find out something unpleasant. In case anything should happen to the pump station, there's an emergency pipeline that can be switched in to bypass it. Our friends took care of that also. They blew up the control valve."
"So there's going to be a massive oil spillage?"
"No chance. The line is loaded with thousands of sensors all the way from Prudhoe Bay to Valdez, and any section of it can be closed down and isolated immediately. Even the repairs would normally present no problem. But neither metal nor men work too well in these abnormally low temperatures."
"Apparently that doesn't apply to saboteurs," Dermott said. "How many were there?"
"Poulson said two. Two others said three. The remainder weren't sure."
"Not a very observant lot, are they?"
"I wonder if that's fair, Mr. Dermott. Poulson's a good man and he doesn't miss much."
"Did he see their faces?"
"No. That much is for certain."
"Masked?"
"No. Their fur collars were pulled high up and their hats low down so that only their eyes were visible. You can't tell the color of a man's eyes in the darkness. Besides, our people had just been dragged from bed."
"But not the two engineers. They were working on the engines. How come at that very early hour?"
Bronowski spoke with restraint. "Because they had been up all night. Because they were going home to their families in Fairbanks for their week's leave. And because I had arranged to pick them up there shortly after that time."
"Did Poulson or any of his friends recognize the voices?"
"If they had, I'd have the owners behind bars by this time. Their collars were up to their eyes. Of course their voices would have been muffled. You ask a lot of questions, Mr. Dermott."
"Mr. Dermott is a trained interrogator," Brady said cheerfully. "Trained him myself, as a matter of fact. What happened after that?"
"Poulson and his men were marched across to the food store and locked in there. We keep it locked because of bears. Unless bears are near starving, they aren't very partial to human beings, but they're partial indeed to all human goodies."
"Thank you, Mr. Bronowski. One last question. Did Poulson or his men hear the fatal shots?"
"No. Both the men Poulson saw were carrying silenced guns. That's the great advantage of those modern educational pictures, Mr. Dermott."
There was a pause in the questioning. Brady said, "Because I am an acute observer of character, George, I can tell something's eating you. What's on your mind?"
"It's only a thought. I'm wondering if the murderers are employees of the trans-Alaska pipeline."
The silence was brief but marked. Then Bronowski said, "This beats everything. I speak as Dr. Watson, you understand. I know that Sherlock Holmes could solve a crime without leaving his armchair, but I never knew of any cop or security man who could come up with the answer without at least visiting the scene of the crime."
Dermott said mildly, "I'm not claiming to have solved anything. I'm just putting forward a possibility."
Brady said, "What makes you even think that?"
"In the first place, you pipeline people aren't just the biggest employer of labor around here… you're the only one. Where the hell else could the killers have come from? What else could they have been? Lonely trappers or prospectors on the North Slope or the Brooks Range in the depth of winter? They!d freeze to death the first day out. They wouldn't be prospectors, because the tundra is frozen solid, and beneath that there's two thousand feet of solid permafrost. As for trappers, they'd be not only cold and lonely, but very hungry, indeed, because they wouldn't find any form of food north of Brooks Range until the late spring comes."
Brady grunted. "What you're saying in effect is that the pipeline is the sole means of life-support in those parts."
"It's a fact. Had this happened at Pump Station Seven or Eight, circumstances would have been quite different ― those stations are only a hop, skip and jump from Fairbanks by car. But you don't take a car over the Brooks Range in the heart of winter. And you don't backpack over the Range at this time of year, unless you're bent on quick suicide. So the question remains, how did they get there and away again?"
"Helicopter," Bronowski said. "Remember I said I thought I saw ski marks? Tim ― Tim Houston ― saw the marks too, although he was less sure. The others were frankly skeptical, but admitted the possibility. But I've been flying helicopters for as long as I can remember." Bronowski shook his head in exasperation. "God's sake, how else could they have got in and out?"
"I thought," Mackenzie said, "that those pump stations had limited-range radarscopes."
"They do." Bronowski shrugged. "But snow plays funny tricks on radar. Also, they may not have been looking, or maybe they had the set switched off, not expecting company in such bad weather."
