Not the vertical shaft of the well behind the altar, but a steep zigzagging passage that cut through the structure, like a switchback mountain road. It connected to a spot in the altar room, a spot that appeared to lie across the gaping mouth of the well. Closer investigation revealed a fissure between two of the stones. Kaufman’s men forced the stone upward with a pair of crowbars, raising it an inch at a time, until it jammed against something and would budge no farther. Lang wedged a two-by-four into the exposed space to brace the stone and then supervised the building of a makeshift bridge above the maw of the pit. He crawled across and peered into the tunnel, using a flashlight. It was a narrow space, perhaps five feet high, but not much wider than a man’s shoulders. It fell away steeply, looking more like a slide than a walkway, and he saw evidence of a pulley and counterweight system for the stone, but whatever flaxen rope it might have once used had disintegrated long ago. Minutes later, Lang was back in the tunnel, this time leading Susan Briggs and four of Kaufman’s hired guns.
