The detail now on show was of a stretch of open country, with a large expanse of water representing an inland lake at bottom right. It was fed by a small river and, coming from the north, a run of high ground and further small streams and other lakes in the foothills of what Brill knew was the Caucasus Mountains. Details of roads were sketchy, mostly because there were none.
Brill glanced at the other technicians. They were intent on the map, and he could feel the tension in the room.
Something was wrong.
He checked the bottom of the screen, where a constant loop display gave map coordinates and current local time, with temperature and weather data on the ground, and a group of six-figure numbers with alpha suffixes. Alongside was a small US flag.
Brill knew that the lights and alphanumeric references represented locator markers on the ground, and showed current strength of signals and position. What he wasn’t privy to was why they were there. All he and his staff had to do was watch them. He scanned the map and data, but nothing sprang out at him.
‘OK, Tully, what’s the probl-’ He stopped, a worm of apprehension taking hold in his gut.
One of the lights was blinking.
‘Is that a malfunction?’
‘No, sir.’ Tully’s voice was tight but controlled, professional. ‘We checked it already.’ He tapped at a keyboard and the map changed, along with the time and data read-out at the bottom. ‘This was thirty minutes ago. Same place, same details.’ The light clusters were the same, but firm and unblinking. ‘The monitors pulled this up as usual, and we ran a check of the last fifteen hours. We noticed that the signal strength had changed overnight.’
‘Changed how?’
‘The lights are ground markers, sir, placed by an insert team.’ He looked nervous.
‘I know. So?’
‘They’re markers, all right, sir… but not ground-based. When we increased the magnification of the area around the lights, we noticed movement. Not great, but definitely movement — in one case by about three hundred metres. A single light. Then it returned to its original position.’
Brill didn’t bother asking Tully if he was certain. The men and women in this room were a highly-trained team, their combined skills probably unrivalled anywhere in the world of electronic mapping and monitoring. And they all had experience of monitoring Special Operations.
‘Maybe they were changing position… or one of them was carrying a marker.’ Even as he said it, he knew that wasn’t the reason. Ground markers or transponders of the type used in this situation were only switched on when in position. The moment they were planted, the man on the ground hit a button to activate the signal. Doing it while on the move was pointless… and could be fatally misleading for back-up forces. ‘Go on.’ He sensed there was more.
The technician brought up another screen, this one enhanced, and pointed to a light close to the lake. We got this read-out earlier… the mover. We think he went down to the lake — possibly for water. He could have been checking his perimeter. Impossible to tell.’
Brill suppressed a shiver. The use of the word ‘he’ suddenly made this much more personal. No longer were they merely lights on a screen, but people; living, breathing people.
‘We think,’ continued Tully, gathering confidence, ‘that these markers are body locators. We thought they were sewn into the clothing. But I’m not so sure.’ He tapped his keyboard and the screen changed again, this time displaying a read-out tag of numbers against each light.
‘I don’t see your point. What’s the difference?’
Tully glanced at his colleagues, then said, ‘I believe these numbers are body-activated. Thirty minutes ago, an alarm sounded. We weren’t sure where it had come from — it wasn’t part of the technical brief. Then we realized it must have come from the locator frequency. Watch this.’ He changed the screen, and an electronic note echoed round the room. It lasted five seconds, then stopped. At the same time, one of the lights began blinking, then went out.
‘What happened?’ Brill felt panic blossom in his chest. Whatever the hell was going on, this didn’t look good.
‘It’s possible these locators are matched to body temperature,’ Tully replied softly. ‘Life-sign readings. When we did a check after the first one down by the lake, we noticed that the numbers against some of the tags changed during the night. They were lower than the others, even those close by.’ Before Brill could ask, he added, ‘When the body is at rest, the pulse and heartbeat slow down and there are no spikes in body activity or life signs.’ The screen changed. ‘This is the first one.’
The light by the lake began blinking, and the electronic alarm pinged.
The light went out.
Brill’s throat went dry. ‘What…?’
‘The locator has lost all life signs. Sir.’ Tully’s voice was a whisper.
Brill reached for a phone. He felt sick. As a naval officer he knew all about transponders. Some were water-activated, for lifeboats and downed aircraft. But a whole new generation of electronics had ushered in innovations for tracking and locating which had less to do with boats or planes and more to do with humans. ‘You’re sure? No chance of malfunction or loss — a failed power source?’
‘I’m sure, sir.’ Tully coughed. ‘Sir, the Yan- Americans have started using small body trackers than can’t be lost or mislaid. They’re powered by body heat and last for approximately twenty-eight days before degrading. Some of our Special Forces are trying them out, too… so I hear.’
‘Go on.’
‘There’s only one reason for them to go offline before then.’
Brill didn’t have to ask what that reason was. ‘How do they work?’ He knew he was playing for time; he hadn’t got the slightest interest in how the tracking devices functioned, or what stopped them working. But neither did he want to make this particular phone call until he was absolutely certain of his facts.
‘They’re inserted beneath the skin, sir.’ Tully pointed to his upper arm. ‘Here.’ He held up a hand before Brill could use the phone. ‘There’s more.’ He turned back to his screen and pointed. ‘This came next.’
Brill waited, holding his breath.
One of the three remaining lights began blinking, followed by the electronic alarm. Then another, this one of a pair slightly separate from the first two. No sooner had it gone out than the fourth light in the cluster went the same way.
The last alarm seemed to go on for ever, echoing with haunting finality in the room. One of the operators swore softly and turned down the volume.
Brill began to dial the number, his hand shaking, and wondered about the men on the ground.
‘Why the fuck didn’t someone tell us?’ he said harshly, staring at the screen. But nobody answered.
THIRTY-TWO
Marcella Rudmann received the news and stared at the telephone before replacing it softly on its cradle. The call from Northwood had been routed through the MOD to all desks, and had already been confirmed by GCHQ and the National Security Agency watchers in Fort Meade, Maryland.
The Delta Force team had gone offline.
Across the desk from her, Lieutenant-Colonel Spake, the Deputy Director Special Forces, looked grim.
‘Four undercover personnel disposed of in quick succession,’ she said. ‘How could that happen?’
Spake raised an eyebrow at the casual terminology, and she blushed, wishing she could retract it, but it was too late. ‘Sorry.’
‘It might have been a bomb-burst,’ he said carefully. ‘Although that’s unlikely. Anything too powerful would show up on the monitors. It might have been a small piece of ordnance — an anti-personnel mine.’
‘What do you think happened?’ Rudmann asked. She knew nothing of battlefield tactics, but if anyone had a workable theory free of over-exaggeration, this man would.
