As soon as they were back in the car, Vaslik took out his phone. Ruth waited to see who he was calling, but realised he was using Google.
‘Damn,’ he said finally. ‘This is hard core.’
‘What is it?’
‘The conference Chadwick attended; it was the Unmanned Aerial Systems Expo at the Allstate Arena near O’Hare International Airport. These things are commercial-level right up to military and law-enforcement grade. They’re used for anything from traffic surveillance through to land surveys, forestry and locating missing persons. Chadwick must really be into this stuff.’
‘He’d have to be good to be invited to take part, then.’
‘I guess. I’ve seen these things fly; it isn’t as simple as it looks and there are all sorts of rules and regulations about where you can use them. Still, it doesn’t tell us why this mystery man was trying to get Chadwick to show him how to use them.’
‘Maybe he was genuine and after some easy help.’
‘What, twenty-thousand bucks’ worth? That’s a lot of money for a startup to throw around. I’m pretty sure there are Xbox generation kids out there who could do it for next to nothing.’
‘How far are we from the Cruxys office?’
‘About fifteen miles or forty minutes if the traffic’s good, maybe longer. Why?’
‘I need to make a couple of calls, one on a secure line.’
Vaslik started driving while Ruth dialled up the Cruxys office to warn them that they were coming in. The local bureau chief – and thus far, the only employee in situ – was named Walter Reiks, an FBI veteran, and he promised to be there to help them. They were soon in moderate to heavy traffic heading towards New York City. Ruth closed her eyes and tried to make sense of things while she had the chance. Everything told her that James Chadwick was in trouble. He had a good relationship with his son, a not-so-good one with his wife, and a burgeoning closeness to Valerie DiPalma that looked from one side as if it might go the distance. So why would he simply disappear without explanation? Work stress might have contributed, but from what they knew so far, he hadn’t seemed on the edge of a breakdown.
Except there was the mystery man from Chicago and the watcher from Newark to account for. What the heck was that about?
They arrived at the office, which was in an unimposing twelve-story building on W 31st Street, and made their way up to the sixth floor. Vaslik was carrying a plastic bag containing the knife and the hardhat. A man with a buzzcut and the obvious look of a law-enforcement professional was there to greet them, standing by an empty reception desk.
‘Good to meet you both,’ he said briskly, shaking hands. ‘Walter Reiks. We’re still setting up here so please forgive the lack of decoration and formality. There’s an office and a secure line you can use down this way and I’ve arranged coffee in five minutes. Let me know if you need anything else.’
‘You’ve been briefed about the Chadwick Code Red?’ Ruth asked him.
‘I have. Any news so far?’
‘A little,’ said Ruth. ‘But so far it’s muddy and not looking great. We’ll circulate a report later for all eyes.’
‘I look forward to it. Come this way.’ He led them to an office with two chairs and a desk, and left them to it.
Ruth called London and got through to Aston, and gave him a brief summary of what they had discovered so far. It sounded disappointingly little in the telling, but Aston was quick to acknowledge that it was early days. His voice on the speaker unit sounded calm and encouraging.
‘What do you need?’ he said when she finished speaking.
‘The first thing is talk to Elizabeth Chadwick again, and if possible, her son Ben. There’s something that doesn’t quite gel about Chadwick’s expertise with UAVs or drones. So far it’s the only thing we’ve found that might offer an explanation about his disappearance. If he’d got an in-depth knowledge about drones, it might help to know where he got it.’
‘Is there anything that stands out?’
‘Two things. He’s always had an interest in flying model airplanes. But radio-controlled kits are a long way from drones.’
‘What else?’
‘He used to be with Air Force Intelligence.’
‘Really? That’s something we didn’t know about. I wonder why he didn’t disclose it. But I think that might be your answer. The US has a highly advanced drone development programme and they’re not all about warfare. There’s a constant spill-over into commercial use with smaller machines. Can you follow up his record locally?’
‘Andy Vaslik already tried. Chadwick’s service record was on restricted access… and it got pulled a month ago.’
‘It would be good to know why. He left the USAF what – four years ago?’
‘That’s right. But maybe they’ve got him on a string as a reservist.’
‘Or somebody thinks he’s gone rogue, in which case they’ll be on his trail, too. I’ll leave it to you to do some digging, but be careful. In the meantime I can patch you through to Elizabeth and Ben Chadwick; we’ve got them at a safe house. Hold one.’
Seconds later, she had Elizabeth on the line. She sounded stressed and irritable, rather than concerned. ‘How long are we going to be kept here?’ the woman demanded. ‘I have a life to lead and Ben needs to be back at school. Have you found him yet – and why are we being forced to hide like fugitives?’
Ruth bit her tongue and said, ‘Not yet. I’m sorry. We have some leads but I can assure you that James isn’t doing this on purpose.’ She was tempted to tell Elizabeth of their suspicions that her husband had been taken for unspecified reasons, but knew that would do more harm than good. Instead she said, ‘We only moved you because we found information that led us to believe your address and Ben’s school address had been taken during a break-in at James’s Newark apartment. It could be entirely unconnected, but I’m sure you can see why, with James’s disappearance, we didn’t want to take any chances. Keeping you and Ben safe is our main concern. It’s what James would have wanted.’
‘I see. I’m sorry, I didn’t mean—’
‘Please, don’t apologise. I’d be climbing the walls if it were me. The thing I have to ask is, you mentioned James had an interest in flying model airplanes. How involved was he and at what level?’
‘What? How does that help find him?’ Elizabeth replied. ‘He flew models, that’s all I know. He always had done since he was a boy, I think. Frankly, it never interested me and still doesn’t.’
‘In that case can I speak to Ben, please?’
‘Why?’
‘Because he might know more about James’s interest in models. I know it sounds odd, but the more we know about James, the greater chance we have of finding him.’
‘I see. Wait.’
There was a long silence than Ben Chadwick came on the line. He sounded very young and worried. ‘Hello? Have you found my dad?’
‘Not yet,’ said Ruth. ‘Ben, my name is Ruth Gonzales. You can call me Ruth. I’m in New York helping to search for him and it looks like we could do with your help.’
‘Me? But how? I mean, I don’t know anything.’
‘You know about flying models, like your dad does.’
‘Oh. Right. What kind of investigator are you?’
‘I look for missing people.’
‘Do you always find them?’
‘Always. Nobody can stay hidden for ever, Ben. Everybody leaves a trace, and it’s up to me and my partner, Andy Vaslik, to find those traces.’
‘Are you a cop?’
‘I was once. Andy, too. He’s American and was with Homeland Security. You’ve heard of them? Like the FBI.’
‘Of course. Man, that’s cool.’ There was a rumble of conversation and he said, ‘Sorry – what do you want from me?’
‘How good was your dad with flying machines?’
There was a short silence, then he said, ‘He was fantastic. He knew all about them. Gliders, kit planes, model helicopters – all of them. He was going to take me to an exhibition this week but he wasn’t able to make it.’ His voice faltered on the last few words.
‘Drones. Did he ever talk about drones?’
The boy’s voice perked up again. ‘Yes. He said drones had changed the nature of warfare. I saw some television programmes about them and I saw what he meant. Reapers and Predators, they’re called, and they carry weapons.’ He paused and his voice went low. ‘They kill people.’
‘What about small ones, Ben? Did he talk about small drones, like the kind they use to monitor traffic and take aerial surveys?’ She was aware of Elizabeth in the background probably on the verge of freaking out at all this talk of weapons and killing and in danger of closing down the conversation just when it was getting interesting.
‘Yes, a lot. He said they were as different from kit planes as Formula One cars are from family sedans. He called them sedans instead of saloons, but I knew what he meant. You know he’s American, right?’
‘I do, Ben.’ She put a smile in her voice and hoped it was apparent at the other end. ‘Your dad’s a bit of a geek about drones, then?’
‘Way more than a bit. I’m doing a science and tech project at school, and he’s given me loads of stuff to use. I’m hoping to have a drone of my own one day and he’ll teach me to fly it.’
It was her opening for the next question. ‘So he knows how to fly them, too?’
‘Of course. He’s an expert. He told me once that he gets calls from all over asking him to talk about them. It’s not his job but he does it for fun. He showed me a DVD once where he was racing other drones over a course using GPS coordinates. He won by a mile. You know what that is, GPS, don’t you?’
‘Yes, Ben, I know. Where was this race?’
‘I don’t know. Somewhere in the States on an air force base. He tells me this stuff all the time, but I don’t always remember the details, because some of them are complicated.’ He paused. ‘I don’t mean complicated.’
‘Confidential?’
‘Yes, that’s right. But he doesn’t tell me anything secret.’
There was more murmuring in the background and Ruth knew the conversation had run out of time.
‘I’ve got to go,’ said Ben hurriedly. ‘It’s been great talking to you, Miss Gonzales. Find my dad. Please.’ Then he was gone and his mother was talking.
‘Was all that really necessary?’ she muttered angrily. ‘You got him all excited talking about flying models. How does that help?’
Ruth counted to five, telling herself that beneath the anger and resentment, Elizabeth was worried, probably as much for her husband as her son’s future. She wondered how she herself would be feeling if she was being kept in a safe house without any information about when she might be able to go home.
‘I’m sorry, Elizabeth,’ she said calmly. ‘Ben’s been a great help and I appreciate you letting me talk to him. He’s being very brave.’
‘Braver than me, you mean? I’m sorry. Call me when you have anything.’
The phone clicked and she was gone.
Ruth looked at Vaslik, who shrugged. They both turned as the door opened and Walter Reiks appeared. He looked worried.
‘Sorry, folks,’ he said quietly. ‘I’ve got a couple of people out here waving badges. They say they’re on official business.’
‘What sort of business?’ said Ruth.
‘They want everything we’ve got on James Chadwick.’
