"Frankly, no. But as far as I can tell from the topographical chart, this track will take us into the area directly below the castle, and that's about as close as we can get to the caves that are marked on the map."

"I don't want to rain on your parade, but surely if the caves are marked on the map, people will have explored them already. The people who did the survey for the topographical chart, for example."

"Not necessarily. Mapmakers make maps: they don't normally also explore the landscape. It's quite possible that they will simply have noted the entrance to a cave and its approximate internal dimensions, and left it at that. I doubt very much if they would also have explored or surveyed the caves, because that really isn't their job."

Mallory grunted as the front wheels of the car dropped down into a deep rut and the whole vehicle bounced and shuddered. "But you're right about other people wandering around the hillside and having a poke about inside any caves they noticed. If we're reading the clues correctly and Tibauld did store the treasure here, that does make sense because he would have needed to choose somewhere with fairly easy access, but at the same time it would have to be a place that offered some kind of security, so that no opportunist just wandering into a cave would be able to find the chests or whatever the treasure was stored in."

Mallory glanced through the windshield at the shape of the castle on the mountaintop above and to their left, then turned his attention back to the track in front of them. "According to the map, there's a turning area at the end of this path. We'll park the car there and then start walking."

"And you still think that's the right place to search?"

"I hope so. But now that we know the shape of the castle, it does make sense of that strange mark, the kind of stylized double capital letter L, the small L on top of a large L, that was scratched underneath the carving of the Beauseant we discovered at the Sidon Sea Castle. The layout of the main walls of the castle is exactly that shape, the lower walls forming the larger letter and the upper ward the smaller. And the mark that was carved on the right-hand end of the larger letter L could easily be interpreted as an arrow, pointing us in more or less the direction we're going now. In fact, the turning area or whatever it is at the end of this track is more or less directly in line with the lower wall of the castle, so I think that's probably a pretty good place to start looking."

A minute or so later he pulled the car to a stop in a roughly circular area of rough ground. Then he started moving forward again and turned the car around so that it was facing back in the direction from which they had come. He parked it on one side, so that any other vehicle following them would also be able to turn around easily.

Before he did anything else, Mallory stared back along the track they'd just driven along, then looked back up the slope towards the old castle.

"What is it?" Robin asked.

"Just checking that nobody's followed us," he said. "I haven't seen anyone taking any interest in what we're doing, but by now those Italians probably know we're on the island, even if they don't know exactly where we are."

But he saw nobody. No car had followed them down the track, and he couldn't see anyone near the castle looking in their direction.

"I think we're okay," he said.

"I hope so," Robin replied. "I'd hate to have the bad guys turn up now, not when I think we're so close to the end of the trail."

They got out of the car, and while Mallory opened the trunk to remove a rucksack containing a couple of large bottles of water, a heavy flashlight, and a packet of spare batteries, plus a few tools that he had thought might be helpful, Robin looked up toward the peak of the mountain.

"I see what you mean," she said. "This spot is almost directly in line with that lower wall. But where do we go now?"

Mallory looked back the way they'd come, then stared at the steep slope that lay beyond them, in the opposite direction.

"If that symbol was an arrow," he replied, "then what we're looking for must be somewhere over there. And if the inverted V shapes on the carving represented caves, which seems to me to be the obvious explanation, then we're looking for three of them, probably situated fairly close together, and almost certainly the important one is in the middle."

Because they had expected to do a fair amount of walking, both were wearing stout lace-up leather shoes with heavy-duty soles and trousers and had lightweight anoraks, because they knew the temperature would fall the higher they climbed. In fact, it was quite a bit warmer than either of them had expected, and so the anoraks stayed in the trunk of the car, along with Mallory's computer bag.

"Are you sure about that?" Robin asked. "I thought you normally slept with it."

Mallory smiled at her.

"I do, almost," he said. "But I think in the circumstances, bearing in mind that we're going to be scrambling around inside caves-or at least I hope we are-it's probably actually safer left locked up in the car. The last thing I want to do is drop it." He tapped one of the zipped pockets on his trousers. "And I've downloaded everything that's really vital onto this external hard drive, so I do have a backup as a last resort."

Mallory picked up the rucksack and hoisted it onto his shoulder, and after a final check to make sure that the car was locked, they set off, picking their way horizontally across the slope in front of them, trying to maintain a more or less straight path. The air was warm, thick, and muggy, and within just a few paces both of them had started to perspire.

"I know we've only just started," Robin said, "but how far do you think we'll have to go? I mean, are we there yet?"

"Probably not all that far," Mallory replied with a chuckle. "If we get a long way from the peak, then I think we can be fairly certain that we've missed it, because then it wouldn't be 'under the castle,' which I still think is what Tibauld meant. My guess is that the hiding place was probably within visual range of the castle, simply so that the garrison, or perhaps a few trusted and selected members of it, could see if anybody approached it. And practically speaking he wouldn't have wanted the treasure to be too far away in case he needed to access it. So the short answer is that we shouldn't have that far to go."

Within about eighty yards, the slope they were walking across terminated in a rock face that barred any further progress. A short distance over to their left was a cleft in the rock that presumably was one end of what looked like a fairly narrow and constricted ravine. Mallory ignored that, and instead turned to his right and began making his way along the cliff face, looking for any indication of a cave or an opening.

And almost immediately they found one.

The cliff face was rugged and uneven, and had a considerable amount of vegetation growing along its base. Behind two large bushes growing quite close together, Mallory spotted an opening. It was roughly square in shape, perhaps six feet wide and five feet high, but even without entering the space he could tell that it was small.

"It's a cave," he said, "but not a big one, and unless the others are really well hidden, it seems to be the only one along this stretch of cliff."

"But we are going to check it out," Robin insisted.

"Definitely," Mallory agreed, reaching into his rucksack and taking out the flashlight.

They stepped forward, moving through the entrance to the cave and into the gloom that lay beyond. The contrast between the brilliant sunshine outside and the darkness within was startling, and for a few seconds they just stood there side by side as they waited for their eyes to become accustomed to the lower levels of light inside. Then Mallory switched on the flashlight and moved the beam slowly around the interior of the cave.

Like the entrance, the interior of the cave was roughly square, but it was small, perhaps only eight or ten feet in length and about the same in width, while the roof height varied between about five and seven feet. Close to the entrance, one of the walls was somewhat blackened, presumably evidence of fires that had been lit there in the past, a deduction that was supported by a rough circle of stones that had clearly been used as a rudimentary hearth.

"Somebody's obviously been in here," Mallory said. "Maybe a shepherd or a goatherd has used this cave as a temporary shelter in the winter, if they bring their animals this high up. Otherwise I suppose a wandering hiker or two might have used it. But I don't see any evidence of a medieval presence here. Do you?"

"None at all," Robin agreed. "But at least this proves that you were right and that there are caves in this area. It just means we haven't found the right one yet."

They stepped out again into the bright sunlight and made their way slowly along the cliff face, looking out for any other openings in the rock. But the outcropping was not particularly big, and in a few minutes they had reached the end without finding any other caves or openings apart from a couple of narrow cracks barely wide enough to accommodate a human hand.

"The carving back at the Sidon Sea Castle indicated that there should be three caves here-assuming that our interpretation of those inverted V shapes is correct, of course-and so far we've only found one," Robin said. "There was nothing over to the right of it, so maybe the other two are over there, on the far side of the entrance to that ravine."

They walked back the way they'd come, retracing their steps along the base of the cliff. But although they followed the cliff face as it curved around to the west, beyond the entrance to the ravine, and looked carefully behind every single patch of vegetation, they saw no sign of any openings or gaps in the rock that would accommodate anything much bigger than a rabbit.

"I suppose that kind of proves a negative," Mallory said. "We now know that wherever the three caves are, they aren't anywhere along this cliff face."

"I have a feeling that we might have more luck in that ravine," Robin replied. "Just thinking back to that carving at Sidon, the representations of the caves were lined up horizontally on the stone. If the purpose of that stylized letter L was for us to walk away from the castle, then the implication is that we would pass the caves as we did so, while we were heading more or less northeast. But if the caves had been located along this rock face, then I think the carver-Tibauld de Gaudin or whoever was acting on his instructions-would have placed the symbols one above the other, in a vertical line, because that would have been a more accurate representation of the geography."

A few moments later, they turned left and stepped into the entrance to the narrow ravine. The shape struck them immediately. It was as if some mythical giant in the days of the ancients had swung a massive ax, smashing the head down and driving a narrow gully through the stone. And that wasn't the only impression that they both immediately had.

"Sidon again," Robin said, and Mallory could hear the excitement in her voice. "That other shape carved into the stone, the letter V lying on its side and pointing back toward the carving of the Beauseant. That's exactly the shape of this ravine. This could be it. It really could."

"Right. Let's hope so," Mallory agreed, realizing immediately that she was right. The ravine was shaped like an elongated V, the apex pointing back toward the old castle, and it was aligned roughly southwest to northeast, more or less along the extended line of the lower wall of the castle of Saint Hilarion. It did all seem to fit with the image they had found carved on the old stone back in the Sidon Sea Castle.

"This ravine is pretty narrow," he said, "so why don't we split up? You cover the left side and I'll take the right."

The left-hand wall of the ravine was almost sheer and largely featureless, just a few small shrubs and bushes hanging on to life and clinging to what soil there was in the few cracks and ledges on the stone. The vegetation growing at the base of the cliff was comparatively sparse, and Robin was quickly able to confirm that there were no obvious caves or openings visible.

Mallory, on the other hand, was faced with thick undergrowth that necessitated him pulling branches aside in order to see what, if anything, lay behind them. Nevertheless, within a couple of minutes he had discovered an opening. Another fairly small cave, which he looked inside briefly before calling Robin over and pointing it out to her.

"If you're right," he said, "this could be the first of the three caves indicated on that stone, so rather than waste time looking inside this one, let's see if we can find the other two."

Because it was clear that there was nothing to find on the left side of the ravine, Robin joined forces with Mallory and the two of them began working their way along the right-hand side, taking it slowly and ensuring that they didn't miss anything. But it wasn't until they were almost at the end of the ravine that they found a second cave. Before they went into it, Mallory and Robin walked out of the northeastern end of the ravine, but there was no sign of any other opening in the rocks as far as they could see.

"Two down and one to go," Mallory said, striding back into the ravine. "In fact," he added, "if this is the second cave, the middle one, then this is what we've been looking for."

"That seems too easy," Robin objected. "This cave is right down here at ground level. Anybody could walk in and stroll away with anything they found. I was expecting Tibauld's cave to be either pretty inaccessible or really well hidden."

"Sometimes the easy option is actually the right one."

"What's that? 'Philosophy for a Really Lazy Man, Chapter One'?"

"Not really," Mallory said with a smile. "Just a random thought, I suppose."

They stepped inside the gloom of the second cave, but apart from a handful of discarded beer and soft drink cans in one corner, there was no evidence that anybody, and especially not a group of medieval knights, had ever been in there.

"I hate to say it," Mallory said, "but this looks like a busted flush. Either that or we haven't found the right cave yet."

They stepped outside again and for a few moments both stood in silence, looking up and down the ravine. Then Mallory shifted his gaze upward, to look at the upper levels of the rock walls on either side of them. The rock on the western side was almost sheer and clearly possessed no openings of any sort, and because of its orientation it would have been in sun for most of the day. The eastern side, in contrast, was comparatively broken up, had at least twice as much vegetation growing on it, and it was possible that some parts of it would normally be in shadow. There was also what looked like a ridge running along most of that side, perhaps twenty feet above the floor of the ravine, and whatever was on it was invisible from where they were standing.

To Mallory, that looked like a much more interesting-and a far more likely-prospect.

"I think we should go and have a look up there," he said, pointing toward the edge of the ridge.

"Suits me. I think we're just wasting our time down here."

There were no paths leading up from the floor of the ravine, but the broken surface on that side meant that it was a comparatively easy climb. A couple of times they each lost their footing, but without mishap, and within about five minutes they were standing on a long and narrow ledge, a mixture of rock and grass underfoot. Presumably because of the fractured nature of the stone on that side, the area possessed thick undergrowth, which would clearly conceal any cave that might be there. There were no signs that the ledge had been visited by anyone at any time, and all Mallory could see on the ground were a few droppings probably from either goats or rabbits: he wasn't a competent enough biologist to know the difference.

They made their way slowly forward, pulling back branches on bushes to check behind each one as they made steady progress along the ledge. But every spot they looked at displayed only the featureless surface of the rock, and both began to feel increasingly despondent.

"I don't think it's here," Robin muttered.

But at that moment, Mallory pulled back a hefty branch from a large and bushy shrub, and behind it both of them immediately found themselves looking into the darkness of a small cavity in the rock.

"Bingo," Mallory said.

The undergrowth largely obstructed the entrance to the cave, and for a fleeting moment Mallory wished he'd brought a machete. But within a couple of minutes they had made their way inside the cave and were able to look around.

"You do realize that this is roughly halfway between those other two caves we found in the ravine?" Robin asked.

"I do now," Mallory replied, and switched on the flashlight to flood the cave with light.

It wasn't a particularly impressive sight. The entrance was probably only about four feet wide at the base and perhaps five feet high, the sides narrowing markedly higher up, while the cave itself was bigger than the entrance suggested, perhaps fifteen feet wide at the maximum, at about the halfway point, and roughly twenty feet deep, the far end tapering almost to a point.

But there was not the slightest sign that it had ever been used for any purpose at all by human beings.

"I'm beginning to get a bad feeling about this," Mallory said. "Apart from the fact that it's a bit bigger, this cave looks exactly like the others."

"You're right, but that doesn't mean we're not in the right place. This cave is inaccessible, and it's also hidden from view, which is what I would have expected if Tibauld had chosen this as the place where he was going to hide the treasure." She paused for a moment and walked back to the entrance, glanced around outside, and then strode back. "Part of the castle wall is visible from here," she added, "and that's another point in its favor."

"It can have as many points in its favor as it likes," Mallory retorted, "but that doesn't alter the fact that there's nothing in here now. This is just an empty shell. If this cave ever was used to store the Templar treasure of Outremer, either Tibauld himself or some other member of the order must have come along at a later date and removed it. Maybe they did decide to take it back to France or just to another location in Cyprus or somewhere else in the eastern Mediterranean, and for some reason that fact was never recorded in the Templar archives."

"That's not necessarily true. I wasn't expecting to walk into the cave and find half a dozen ironbound chests just sitting there. Tibauld wasn't stupid, and even with the entrance to the cave being virtually invisible and very probably being watched from the castle above, he would still have wanted the treasure to be concealed. There might well be some kind of hidden partition or something of that sort in here."

Mallory laughed shortly. "You mean that sometime in the fourteenth century, in a moderately inaccessible cave in the middle of Cyprus, some medieval engineer turned up and built a false wall? Like a Bob the Builder of the Middle Ages?"

"Don't knock it. Medieval engineers were a lot cleverer than most people think. Don't forget the book safe."

Mallory nodded.

"Point taken," he said, bent down, and picked up a fist-sized lump of rock from the floor of the cave. "If there's a false wall in here, I promise you that I'll find it."

He stepped over to the left-hand side of the cave and rapped the stone sharply against the wall. The unmistakable sound of stone on stone rang out. "Solid as a rock. In this case, literally."

He moved on, working his way down the side wall of the cave and using the stone as a hammer, listening out for any indication of a cavity. At the far end, he had to work his way around a pile of fallen rocks to reach the right-hand wall and return toward the entrance, where Robin was waiting.

"I'm sorry," Mallory said, "but unless I'm missing something the walls are absolutely solid." He tossed the stone onto the ground in disgust. "If the Templar treasure ever was here, it's long gone now. I'm afraid we've been wasting our time, chasing shadows and following ghosts. Let's get out of here."

But Robin didn't move, staying right where she was and staring toward the back of the cave.

"What is it?" Mallory asked.

For a few seconds, Robin didn't respond, just continued looking in the same direction.

"What is it?" Mallory repeated.

"It's the rocks," Robin said. "They're wrong."

Mallory switched the flashlight on again and shone it at the pile of tumbled boulders at the far end of the cave.

"What do you mean 'wrong'?" he asked. "It's just a pile of old rocks."

Robin shook her head. "No, it isn't. When I came in here and looked around for the first time, I saw the rocks just as you did, and like you, I guess, I assumed that that was a result of a rock fall centuries ago. But I was wrong, and so are you."

Mallory lifted the flashlight beam so that it illuminated a part of the cave roof, then dropped it down again, back to the rock pile. "You're obviously seeing something that I'm not. What I see is a pile of old rocks. What do you see?"

"I see a pile of old weathered rocks," Robin replied.

For the first time, Mallory actually focused his attention on the rocks themselves, rather than on the shape of the pile. And he realized that Robin was right. Unlike the walls of the cave itself, which were largely clean, untouched by wind or rain, the rocks at the far end of the cave had clearly spent many years exposed to the elements. They were, without a doubt, weathered rocks. What he didn't see was why that should be important. "So?"

"So why would anyone bother to climb up to this moderately inaccessible cave in the middle of Cyprus-I think that was how you described it-and then carry about half a ton of rocks into it from the outside? That just doesn't make sense. Or rather it only makes sense in one context. This was the cave in which Tibauld de Gaudin concealed the Templar treasure of Outremer, exactly as we thought, and he hid it in a hole at the far end of the cave. Then he covered it over, probably with heavy wooden planking, and piled rocks on top of it to hide it from prying eyes. The only mistake he made was to have his men collect rocks that had been outside for years, but he probably had no option because there weren't enough inside the cave to hide what he'd done."

She pointed at the rock pile. "And unless somebody thought it was a good idea to remove the treasure and then replace the wooden planking and all the rocks again, to hide the hiding place, as it were, it looks to me as if the treasure is still buried over there, in the place where Tibauld de Gaudin's men originally put it."

61.

Cyprus Shifting the rocks was hard work. Obviously there was no moving air in the cave, and although it was much cooler inside than out, within a few minutes of starting work both Robin and Mallory were sweating profusely. But at least the cave was big enough to allow them to just roll the rocks out of the way, to move them to one side. They didn't have to carry them anywhere, which was a bonus.

Just before they started, they'd taken a moment to look at the area covered by the boulders, which was roughly circular, and Mallory was surprised that he hadn't spotted this apparent anomaly himself. A rock fall would not have been anything like as neat.
