No celestial light penetrated the smothering black storm clouds, beneath which a damp mist rolled across the muddy ground. Somewhere in the darkness a parrot cawed from an enclave in a mahogany tree and the hooting of howler monkeys echoed from nowhere and everywhere at once. Until abruptly the world fell silent. Four shadows peeled from the night at a crouch and emerged from the undergrowth into a small clearing at the base of the steep hillside that had grown over the ancient Maya temple La Danta, converging upon a rickety aluminum shack surrounded by drilling and earthmoving equipment sinking into the detritus. One of the shadows reached the door of the flimsy building, and after a few seconds, a padlock dropped into the mud. Another shadow drew the door wide and all four disappeared inside. Wooden crates and packing material lined the wall to the left, while middle Preclassic Era artifacts from narrow-mouthed tecomate jars to jade and obsidian figurines were displayed in a staged jumble on a table to the right as though someone had merely stepped away from their task of boxing and shipping.
