‘Tell me exactly where she is, you crazy bitch, or I’ll throw you in front of the next train myself.’

‘Oh, Marcus,’ she trilled. ‘How manly you are!’

‘Marcus?’ Bloom placed a hand on his back.

‘Don’t think I won’t do it,’ Jameson said. ‘Jane and the world would be better off without you. Now where the hell is she?’ When Lana failed to respond, he dragged her into the middle of the bridge, his knuckles white on her shoulders. He pushed her to the edge and checked his watch. ‘You’ve got two minutes.’

Bloom watched her partner. She was ninety-nine per cent sure he wouldn’t do it. He was a good man, a law-abiding man. But he’d just told her about the first death he was responsible for. There were more.

‘Marcus?’ she said again. If he was bluffing, he wouldn’t thank her for ruining it. But if she showed just enough fear … ‘Don’t do anything stupid, Marcus.’

‘Where is she?’ Jameson’s voice was low and menacing. She’d never heard him like this before.

‘How do you expect to find her if you throw me over?’ Lana’s voice was still completely calm.

‘She’s right, Marcus,’ said Bloom. ‘Don’t let your hatred cloud your judgement. I know you’ve struggled with those who’ve died at your hand before.’ Lana responded with a hint of panic and Bloom felt a small surge of satisfaction. The woman strained against Jameson’s arm for the first time. She didn’t want to die. ‘If Lana is killed by this train, what will we have gained? She won’t be here any more, breathing, thinking, talking. She’ll be nothing.’

Jameson tightened his grip against Lana’s attempts to wriggle free. ‘Tell me where she is and I’ll let you go. It’s that simple.’

He was playing along. He was still thinking clearly.

Lana stopped squirming. In the distance Bloom heard the low murmur of the next train approaching.

‘Decision time, Lana,’ said Jameson, pushing her further over the edge.

‘You know, I never did like you.’ Lana craned her neck to see his face. ‘And neither does Jane.’

Bloom could see the train’s headlights. ‘Why would you wind him up right now, Lana?’

Lana looked at her and smiled.

And then Bloom saw it. The reason they’d been lured to this spot. The reason Lana had waited all afternoon and into the night for them. This was a demonstration of power. They had somehow discovered Bloom’s biggest weakness and this elaborate theatre was designed to exploit it. They had manipulated technology to lure her here. They had sent Lana alone. They had made it seem like Bloom and Jameson might actually have the upper hand. But it was all an illusion.

The train bore down on them, fast and loud, pushing gusts of air on to the bridge where they stood.
