One of the plaques caught Maura’s eye, and she paused among the flow of tourists to read it. As she struggled to translate the words using her shaky high school French, she heard the incongruous sound of children’s laughter echoing in the dim corridors, and the twang of a man’s Texas accent as he muttered to his wife. “Can you believe this place, Sherry? Gives me the goddamn creeps…”

The Texas couple moved on, their voices fading into silence. For a moment Maura was alone in the chamber, breathing in the dust of the centuries. Under the dim glow of the tunnel light, mold had flourished on a cluster of skulls, coating them in a greenish cast. A single bullet hole gaped in the forehead of one skull, like a third eye.

I know how you died.

The chill of the tunnel had seeped into her own bones. But she did not move, determined to translate that plaque, to quell her horror by engaging in a useless intellectual puzzle. Come on, Maura. Three years of high school French, and you can’t figure this out? It was a personal challenge now, all thoughts of mortality temporarily held at bay. Then the words took on meaning, and she felt her blood go cold…

Happy is he who is forever faced with the hour of his death

And prepares himself for the end every day.

Suddenly she noticed the silence. No voices, no echoing footsteps. She turned and left that gloomy chamber. How had she fallen so far behind the other tourists? She was alone in this tunnel, alone with the dead. She thought about unexpected power outages, about wandering the wrong way in pitch darkness. She’d heard of Parisian workmen a century ago who had lost their way in the catacombs and died of starvation. Her pace quickened as she sought to catch up with the others, to rejoin the company of the living. She felt Death pressing in too closely in these tunnels. The skulls seemed to stare back at her with resentment, a chorus of six million berating her for her ghoulish curiosity.
