Whack!
A sharp whip-cracking sound echoed across the roof as, without warning, one of the four canvas ratchet-straps attached to the chopper’s tail snapped abruptly.
Its tie-down stud had exploded in a short contained blast from a small explosive, just like with the gravity boots in the elevator earlier.
In response, the chopper shunted down a foot, dropping a fraction further over the rim, its landing struts squealing as they scraped against the edge.
Inside it, Yasmina King screamed.
As everyone on the helipad spun, I turned to Audrey.
‘He’s gonna drop the chopper,’ I said.
‘How do you know?’
‘Because he’s playing with us. He’s already shown he knows a hell of a lot. Maybe he knows the insurance policy maxes out at ninety million. We have to do something fast.’
‘But what can we do?’ Audrey said.
I grimaced, thinking.
‘I have an idea, but you won’t like it.’
‘Can I help?’
‘No. If I’m gonna do it, I’ll have to do it alone and I have to do it now,’ I said.
‘Go.’
I bolted off the helipad, heading for the fire stairs.
I bounded down the fire stairs three at a time.
Came to the first floor below the roof, the 98th.
It was another open-air, blow-through level: its broad square ‘windows’ opened onto the sky and a chill wind rushed through them.
As I’d seen on the blow-through level on the 75th floor, this one was a mix of machinery—air-conditioning units, vents, elevator engines—and shed-like rooms and cabinets for storing window-cleaning gear and the like. Several dozen grey concrete pillars supported the ceiling; they were unpainted since nobody but maintenance folk would ever come here.
I saw it instantly.
Over by the north side.
The nose of the chopper.
It was dipping into view outside one of the open-air windows there.
As I ran toward it, I pulled out my cell phone and speed-dialled Audrey.
‘How long to go?’ I asked.
‘One minute,’ she answered.
‘Still three straps holding up the chopper?’
‘Yeah. For now. Where are you?’
‘You don’t want to know.’
