I focused on Vicar, then on the sights. Vicar disappeared into a gray blur. I switched off the safety. There had to be three shots. It's not just pull the trigger and you're done. Got to do it right. Hammer pair to the body. A final well-aimed shot to the head.

The first two have to be fired quick, that's important. Your body is mostly water, so a bullet striking through is like a stone thrown in a pond. It creates ripples. Throw in a second stone soon after the first, and in between where they hit, the water gets choppy. That happens in your body, especially when it's two 5.56 rounds traveling at supersonic speeds. Those ripples can tear organs apart.

If I were to shoot you on either side of your heart, one shot . . . and then another, you'd have two punctured lungs, two sucking chest wounds. Now you're good and fucked. But you'll still be alive long enough to feel your lungs fill up with blood.

If I shoot you there with the shots coming fast, it's no problem. The ripples tear up your heart and lungs and you don't do the death rattle, you just die. There's shock, but no pain.

I pulled the trigger, felt the recoil, and focused on the sights, not on Vicar, three times. Two bullets tore through his chest, one through his skull, and the bullets came fast, too fast to feel. That's how it should be done, each shot coming quick after the last so you can't even try to recover, which is when it hurts.

I stayed there staring at the sights for a while. Vicar was a blur of gray and black. The light was dimming. I couldn't remember what I was going to do with the body.
