Curtain rings, that's what he recalled most clearly, the rings on the shower curtain spinning on the rod when the curtain is torn loose, a moment lost at normal speed, four rings spinning slowly over the fallen figure of Janet Leigh, a stray poem above the hellish death, and then the bloody water curling and cresting at the shower drain, minute by minute, and then eventually swirling down.
