The dead man is lying prostrate on the asphalt!
The assailant stands over him, gun in hand!
And lingering in the air around them is...
The Sweet Smell Of Gunpowder!
THE SWEET SMELL OF GUNPOWDER
Cradle your handgun in both hands, extend your arms, fire off a round and... swoon from the gunsmoke!
Suck the smoke into your nostrils... feel the chemicals coat your cilia to assault your nose neurons.
You are not insulted by your perceptions, in fact... you love the danger of the sweet smell of gunpowder.
And you don't give a shit about the man you just killed because the thrill of the smell of the kill is all you ever wanted!
