Whiteout!

'Sure they were.'

I said, 'But that's crazy! The moment Foster died his account would be frozen. By killing Foster, he made the cheques worthless!'

'That's right.' Barney's hands gestured his own incomprehension. 'Still, here's some more. Supposition: and this one's not all that good. But remember they were stuck in the hut, just the two of them. So maybe Sergeant Vernon was getting round to chiselling even more dough out of Foster. Foster only inherited if he got his discharge with the word exemplary plastered all over it. One charge - indiscipline, insubordination, even failure to maintain personal cleanliness, goddammit - and that conduct sheet would have been wrecked. Vernon really had Foster by the shorts. So you could put together some kind of a scenario in which Foster attacked Vernon first, right? Vernon defends himself, knocks the kid unconscious, panics, and just leaves him out there to freeze. Well, it's possible! Then, when he's back inside Hundred . . , well, that's when he has to work out a story real quick, and he says Foster blundered away from the rope and got lost in the white-out.'

I nodded. 'Then later he realized that Foster's body must still have the line attached. And when it was found .., but would it have been found?'

'Sure it would,' Barney said. 'Come the spring and a little daylight, the whole surface area's gone over. Markers and lines are lifted and repositioned, general tidying-up.'

'And the body tied to the line was positive evidence Vernon had lied.'

'Right. He had to get out and cut that line. But the weather stayed closed. Heavy snow, too, remember that. Soon the whole thing would have been buried deep and there'd be almost no chance for one man alone to find Foster. When he realized that, the shrinks reckon, that's when he started the attack on Hundred itself. It's kind of a classic pattern: the structure's a threat, so he sets out to attack the structure. With Hundred abandoned, Foster's body never would have been found. He'd have lost the money, okay, but he'd have been in the clear.'

We sat and looked at each other. I said, 'There's another thing I've never understood. Why on earth did he muck about with the bodies? Why take Harrer's body out of the trench and put it where the bulldozer would crush it? I mean, dammit, if he hadn't done that, we'd never have rumbled him.'

Barney shrugged. 'Who knows ? He was crazy anyway, but a supposition was slung together. You told us in your evidence that Vernon probably saw Doc Kirton with the food wrappings after that business with the bear. Likely he heard you talking. He knew Kirton wasn't going to find any saliva to analyse, because it was Vernon himself who'd scratched open the oil tanks and the emergency rations. No saliva, no bacteria, so no bear. Therefore proof of sabotage. So Kirton had to go.'

'It's a hell of a supposition!'

'Less than you'd think. Vernon kept a paper he stole from Kirton's office.'

'What paper?'

'Kirton's report. He'd done the microscopic analysis, and written up the results. The report said no bacteria, no evidence of animal saliva or animal hair or animal mucus. Vernon took it, which may have made sense to him. But he didn't destroy it, which just shows how crazy he was.'

I said, 'It still doesn't explain - '

'I know it. Listen: he killed Kirton. Probably did it right there in the hospital. So he had a body to get rid of, right? He puts Kirton on a sled-stretcher and hides him under something, a few boxes, anything, then he hauls off to the well trench, which is off limits, anyway, and not far away, and he knows he won't be disturbed in there as he drops Kirton down the well.'

'I realize all that. But why bring out Harrer's body?'

'Because having dumped Kirton, he realizes Kirton's going to be missed. There'll be a big-scale search. Maybe he's left some clues somewhere, something that leads to him. He hasn't but he can't be sure. Then he remembers there are other bodies, and one of them is Harrer's. Now Harrer doesn't look like Kirton, except they're both big men, and dark. Nobody's going to mistake one for the other, not unless - '

'Now I understand.'

'Yeah. The body's unrecognizable, there's a man missing, two and two make four. Nobody wants to look too close.'

'And the nuclear engineer, Captain Carson?'

' Carson 's body was outside the escape hatch of the trench where he lived. Head beaten in. Vernon must have carried him up the ladder and dumped him outside. He'd fixed Kelleher with drugs and killed Carson . The reactor was going to be out of action a long, long time.'

I said, 'He only missed by a whisker, didn't he? He almost did force Hundred to shut down.'

'He came closer than you think,' Barney said.

'What do you mean?'

'Hundred's closing in the spring.' As I looked athim he seemed infinitely sad.

'Why?'

'That's the Army for you. Research project completed. Shy away from a can of worms.' He shrugged, then gave an apologetic little grin. 'So you see, we won't be needing too many hovercraft.'

'Many! You mean any.1"

'That's right, Harry. There'll be compensation, naturally, but-'

'But no sale,' I said.
