quickly undid the straps and locked the frame’s joints into position.
After loading the bolt gun Stratton positioned the two holes at the top of the frame over the boulder, checking to ensure that the rock was solid and that the bottom corners, where his feet would go, rested on the adjacent slab. Satisfied that it was well positioned, he pressed the bolt that protruded from the end of the gun firmly into one of the top holes, pushing down on it to release the automatic safety lock. He pulled the trigger. A powerful jolt slammed the steel bolt through the eyehole and into the rock. When he removed the gun he gave the frame a tug. The bolt was firmly home.
He reloaded the gun and slammed the next bolt into the opposite corner. In a couple of minutes he had planted all five bolts and the frame appeared to be rigidly in place. But another firm tug revealed a loose bolt at one of the bottom corners. Unperturbed, he loaded a fresh bolt into the gun and tugged at the loose one in an effort to remove it. It twisted around inside the rock but would not come out. A fierce tug on the frame didn’t budge it.
Stratton felt reluctant to spend any more time on the faulty bolt. It would require far more force than he could exert to remove it. Typical of what he disliked about technology, and this was the simple kind, according to Binning. There was no tangible reason, that he could see at least, why any of the bolts should remain in position. It was clear how a screw worked, and even how a nail hammered into wood could hold strong. A bolt punched into rock, and not a very long bolt either, failed to inspire him with confidence.
A check of his watch revealed time quickly moving on and Stratton suddenly feared he might not have enough. He pushed aside any doubts about the frame, untied the gun from his belt and let it sink to the bottom. If the Inessa came at that moment he would fail. He sat on the frame, strapped both his legs to it as tightly as possible, and lay back to secure the waist and chest straps. Before fitting the head harness he found the recorder on the end of its line, opened the container, removed the device and activated it. He set the arming switch and checked the series of LED indicators. The system appeared to be functioning. He removed his face mask, letting it hang from the back of his hood, and placed the cumbersome device over his face, pulling the head straps tight. Exhaling through his nose into the optical compartment displaced the water inside it and he blinked quickly to clear his eyes. A brief adjustment of the lenses brought his immediate surroundings into focus. The device could penetrate low light as well as some of the murkiness, improving overall visibility. So far so good, he decided. He was still not quite ready.
The Inessa would make all haste to get out of the harbour once it had slipped its moorings. It had a speed limit of ten knots in the main channel but the captain was committed to turning on the disrupter and accelerating to a cruising speed of thirty-five knots as soon as he could. He would get out of the harbour as quickly as possible.
Stratton passed the strap that secured the device to his head over the top of the recorder housing, clipped it into place and tightened it. He could only move his arms now. He was firmly secured to the boulders.
As he stared into the hollow grey glow around him, he picked up a faint noise - the water was a more effective medium than air for relaying sound waves. The sound became a distant hum that grew louder by the second. It could have been another ship passing through the harbour entrance but Stratton felt somehow sure it was the Inessa.
The operational briefing had covered all possible contingencies including another vessel passing overhead, or close by, around the time when the Inessa was expected. Stratton’s orders were to remain in position and record everything, no matter what it was. But it would be a pointless risk for another vessel, even one close to the Inessa’s size, to pass that close to the mole. The Inessa’s captain knew the precise depth of the boulders where he intended to pass above them.
