Q: Paragraph- Sent 1: The old vaulted church was stripped down: there was no cloth on the altar, just a DJ's toolkit and his beer.
Sent 2: Through the dark, I could see three bolts left in the wall from where they'd taken down the crucifix.
Sent 3: A confessional too beaten-up to have been sold was shaking in a way that suggested activity inside, and where the pews had been taken out, a couple hundred people were testifying to the DJ's moving sermon.
Sent 4: Rachel stepped forward into the crowd while I took a moment to drink in the ceiling's blue-lit, shadowed vault and the light-catching haze from who-knows-what rising between the DJ and the crowd.
Sent 5: There was a terrific echo, each beat reverberating inside of the next, and the old stained-glass windows rattled in their frames.
Sent 6: On the dance floor, people moved with their eyes closed and their hands in the air.
Sent 7: I danced with Rachel for a while, but then something by the bar seemed to be pulling her eyes.
Sent 8: She told me that she was heading for a drink and slipped out of the crowd.
Sent 9: When she hadn't come back halfway through the next song, I glanced over at the bar.
Sent 10: It was just a little set-up where someone had stacked a few crates and brought something alcoholic to share, mostly beer.
Sent 11: Rachel was standing with a plastic cup, looking like she was having a conversation, but I couldn't see anyone else there.
Sent 12: The next time the crowd split, I saw him.
Sent 13: He stood in front of a blue light, so I couldn't see him clearly, but what I saw was memorable.
Sent 14: He wore a jacket of what might have been blue velvet, and his hair gleamed black against his white skin.
Sent 15: The blue haze seemed to stop just shy of his pallor, setting off his striking face without illuminating its details, and his wrists flashed white in the darkness.
Sent 16: He didn't move, just stared and held his drink.
Sent 17: The next time I saw them, his mouth was moving.
Sent 18: She nodded and he took her arm.
Sent 19: I watched them through the crush of dancers as they squeezed along the wall, and the feeling came to me that something was very wrong.
Sent 20: Saturday morning, I woke up and saw that she still hadn't come home.
