I start pulling crates away from the wall; they're heavy with books, mechanical parts, and old glass containers. I get further in, trying to stay silent as I move them. A dry rattle freezes me in place. I hold my candle lower just in time to see a rattlesnake strike my leg and inject its poison. The cave's residents find me, but it's hours later. Too late. I'm never making it out of this cave alive.
