As close to heaven as they could get.

The echo of Angeli’s voice roused him from his meditation. He forced his eyes back to Photinus and spotted the second set of steps just on the other side of the buildings. His body low, he traversed the top of the wall, then made his way down.

A courtyard opened up at the base of the steps. Scampering across it, he came to a bridge no more than ten feet across, a tiny rill below-more rocks than water-its trickle heard, not seen. He checked the notes; there was no bridge mentioned. Evidently, this was a “recent” addition. Instructed to follow the water upstream, he placed his hand on the bridge’s stanchion and leapt down the five or so feet before making his way along the sod and mud, careful to keep his lamp high. The footing grew more and more tricky, slick rock causing him to keep one hand almost in the water so as to maintain his balance. Forty yards along, he pulled himself back up the bank.

What had appeared as a collision of trees and stonework from his cell window now opened up as the onetime heart of the monastery, the buildings retreating further and further into the past. And yet, the deeper in he moved, the more he sensed a loneliness from those he passed, too many of them abandoned, remnants from a time when Photinus had boasted five hundred monks within its walls. Now it held barely eighty, the rate of apostasy increasing with each year, the malady of “teddy-boyismos,” as Nikotheos had called it-the lure of Salonika-having grown to epidemic proportions. The old monks were dying off, the novices fleeing, leaving the buildings to stand empty and alone.

Pearse felt only token sympathy. The fewer monks around, the less likely he might run into one.

All such concerns quickly faded when, at the top of a steep rise, he came face-to-face with a double row of columns, the facade for a cloister peeking out through the gaps.

This time round, he needed no cats to set his heart racing.

“Twin rows of eight will guard the Vault.”

Somewhere within those walls waited the parchment.

Staring up at the building as a whole, he quickly understood why the Manichaeans had chosen it for their hiding place. He reckoned it stood almost at the center point of the three outer walls. More than that, it had been designed in such a way that, as far as he could tell, access to it was possible only from the route he had taken. The back and side walls seemed to grow out of the mountain, a half-chiseled sculpture tearing itself from the rock. Only the front colonnade was fully realized, the “twin rows” revealing an archway at the center. Pearse removed the last few sheets from his sleeve and started in.

Four portico walkways flanked a narrow quadrangle to form the interior, a courtyard of dusted earth and wild grass at its center. Unlike anything he had seen up to this point, the cloister clung to a late Roman past, a building that might very well have predated even the Manichaean presence at Photinus. Bringing his lantern to eye level-and relying on a suddenly lustrous moon-he followed the line of archways that extended to his left. The stone had softened over the centuries, but the rigid lines of each column could still be seen even in the half-light, the pedestals beneath linked in a continuous low wall. The arcade itself had not faired so well, the flagstones chipped and cracked, clumps of vegetation pushing their way through, odd mounds of dirt scattered throughout, the mark of animal scavenging. Every so often, a window or door would appear along the walled side of the arcade, the rooms within showing equal disrepair, some, though, with hints of long-faded mosaics-a partial crucifix here, the hand of the Virgin there-all shining back at him in the lantern light. From the varying sizes and shapes of the cells, it was clear that the place had once housed a virtually independent community within Photinus, far more than just the simple cloister it purported to be.

Further confirmation awaited him at the third corner of the quadrangle-access to a subterranean level, highly unusual for a cloister of its age. Nestled within a miniature rotunda, he found a set of circular steps leading down. Eighteen of them. The notes were, once again, right on the mark.

Trouble was, it was the last of the detailed entries. The final two “clues” were far more cryptic, abstract phrases, with no directions of any kind. Even on the bus, they had struck him as out of place. “Those who enter may see the light,” followed by the equally vague “The one unmoved takes wing.” He had recognized the first as a biblical passage, somewhere in Luke his best guess, but pinpointing the source had done little to explain its meaning. The second had baffled him altogether. He had hoped that by now something would have appeared to clarify at least one of them; otherwise, why make the map so specific, only to leave the most crucial bits indecipherable? He was faced with two possibilities: Either the Manichaeans had thought the phrases obvious enough on their own or they had decided to throw in one last bit of “hidden knowledge” to keep things interesting. A touch of the gnosis at the bitter end. Had he been a betting man, Pearse would have opted for the latter, which meant that if he was going to find the parchment, he had to start thinking like a Manichaean.

Reaching the bottom of the steps, he could make out little more than ten feet in either direction, the lantern light only sharpening the vacancy beyond. It was enough, though, to see that the lower level was a virtual carbon copy of the cloister above, save, of course, for the central courtyard, which here had become a mass of solid stone. A pair of corridors branched out from the corner stairwell, the first legs of the quadrangle disappearing into a dusted emptiness. Gone were the sounds of the night that had accompanied him thus far, the absolute quiet matched only by the unrelenting darkness.

Lamp at arm’s length, he started down the corridor to his left, his focus on the side walls, uneven rock chiseled from the mountain. From time to time, a rusted torch holder would appear, centuries beyond use, bits of stray iron hanging precariously from eroded pins. As to the cells, they came at regular intervals, six to eight paces between each, tiny hovels drawn of all air, dirt floors beneath. Surprisingly, several of them retained the faint aroma of burned leaves-why, he couldn’t explain-instant memories of long-ago bonfires quickly erased by the immediacy of the place. More difficult was determining what most of the rooms had been used for-storage, prayer, perhaps even ritual-bits of mosaics once again scattered throughout. He spent several minutes studying the tiles, hoping to find something that would invite him to “enter” and “see the light,” but there was nothing. Only a neat pattern of cells to bring him back to the stairwell, no farther along than when he had set off.

Undaunted, he retraced his steps. When he reached the stairs for a second time, he planted himself against the rock and closed his eyes. The need for a little guidance. Where would they have hidden it? The silence brought him back to the notes. It’s a game for them, he thought as he stared down at the pages. So how would they hide the “knowledge”? For want of anything better to do, he counted out the Syriac letters. Thirty-five. No luck there; the cells had stopped at twenty-two. Evidently, the Manichaeans hadn’t placed much stock in numerology. Look at the words. It has to be in the words. He continued to stare at the phrase. “Those who enter may see the light.” The light. He knew it was no metaphor for them, no spiritual allusion, but something tangible, real. Up to this point, he’d assumed “the light” had referred to the parchment. That was real. Enter and find it. Clearly, that wasn’t the case. So what down here contains the light? He began to wonder if he’d somehow missed a tray of melons along the way.
