Both knew they should have made some kind of plan, but they hadn’t. After all, if their surmise was correct, they were about to confront a young man who might well be a murderer. Having guarded his privacy so fiercely for three weeks, how was he likely to react to the discovery of his hideaway? If he had already killed Kyra Bartos, would he be worried about the killing of two inquisitive middle-aged women, so long as it kept him safe from the attentions of the police?
The opening of the door at the back of the fireplace, though quiet, had not been entirely silent. It was a sound their quarry would know well. Mopsa had quite possibly told him that she was going out, so he would know they were intruders. The welcome he was preparing for them could be ugly.
And yet still neither of them said anything. Instinctively, Jude drew back and let Carole lead the way. They didn’t even look around for a torch. From whatever was at the bottom of the steps a thin light flowed.
They had not defined in their minds what they were expecting to see, but neither had anticipated the bright airy space they stepped into. The light was natural, sunlight streaming in individual, focused beams through narrow fissures in the natural rock of the walls. These openings, created by the erosion of the exterior cliff face, were too high up the walls to offer any hope of escape. But the chamber their light illuminated was not the primitive cave Carole and Jude’s imaginations had suggested. It appeared to be a section of a circular vertical mineshaft, some twenty feet across, which would have reached the surface right next door to the Lockes’ cottage. But, many years before, the space had been separated off by a wooden floor and ceiling to form the hidden room. The carpentry had not been professional, there was a rough-hewn quality to everything. But it looked sturdy and secure. The smugglers of Treboddick had known what they were doing when they constructed the Wheal Chamber.
These were the peripheral impressions of a nanosecond, because what arrested the attention of both women was the figure sitting at a table facing the sea. They had seen the family photographs and had no doubt that it was Nathan Locke.
The shock they both felt, though, arose from their assumption that he had hidden away of his own accord. They hadn’t expected the chain from an iron ring on the wall which was attached to the boy’s ankle.
