‘But what you weren’t expecting was Lucy’s reaction, for her to recognise the victim as the policeman who’d given her a speeding ticket on the way up. When she stormed out, I thought she said, “You’re the boss”. But she actually said, “It’s your boss.” She hadn’t thought to accuse you yet – she was thinking aloud – but she knew something was off. She didn’t put it together until she got up to the roof and googled the Jindabyne police department. But by then we’d filtered off to bed and you’d followed her up there, and she didn’t want to die like Michael, so she jumped.

‘You lied about how you got here so fast too. You said you’d been on the speed radar all night catching tourists, but that can’t have been true because Lucy, at some point, would have surely spat on you over the ticket she got. More police were never arriving – you told us they were caught dealing with the roads, but how do two passenger coaches get up here and one police car can’t find its way when there have been two murders? Of course, none of this twigged at first. You seemed reliable. There were three sets of footprints to the body and only one back: enough for one victim, one arriving policeman and one killer who’d left. I thought this meant the killer had called in the body themselves, before’—I used air quotes here— ‘Officer Crawford had arrived, being the third set. I was right that the killer did call it in, or at least pretended to. Because no one else discovered the body, you discovered it yourself – it was part of your act. You went up there twice. First, with the sergeant, when you tied the bag around his head, walked him up there to die, and then took his coat, and then again in the morning.’

‘He’s on camera arriving much later.’ Juliette sounded unsure of my conclusions. ‘We both saw that.’

‘I think you’d been checking out the resort when you were planning to follow us up here. And the snow cam is on their homepage, so you knew the driveway was, in a way, monitored. I assume you attacked the sergeant on the road, where he’d have parked his patrol car to set up the speed gun. At the top of the hill you would have had mobile reception to check the website. I’d thought myself that if you really floored it, a car could skip the three-minute window where the camera refreshed. Then you just needed to go back later and make sure you were captured arriving at the correct time. It looks like you’re travelling towards the car park in the photo, sure, but your arm is over the back of the headrest. You’re reversing.’
