Murder is a full-body experience. Your pulse rate will spike, your skin flushes with heat, your palms dampen with sweat. Beforehand, it is not uncommon to have second thoughts, pre-party jitters so to speak. Once the process has started, however, crossing the street, sneaking into the backyard, prying open that never completely secured window . . .
A calm will descend. A predatory Zen state, where the air tastes crisper, the smell of her shampoo registers sharper, while the sound of her first muffled scream, caught in the latex-covered palm of your hand . . .
Sound and scent will become snapshots, frozen forever in your mind. A slide show of sensory indulgence, her panting breath, matching the equal racing of your heart, her kicking struggles, the corresponding flex of muscle and power in your own limbs. Her sheer, desperate need to escape. Your own equally compulsive, biological imperative to kill.
You will feel stronger, hear better, smell sharper, taste finer, and see crisper than ever before. As long as you stay in control. No panic, no frenzy, no mistakes. Ride the ride to her last, gasping, gurgling breath. Killing is about power, but it is also about self-control.
Mentally prepare for the physiological overload. This is step four.
