Evil Villainy: The Porfect Moider

So our evil villain twirls his mustache and thinks aloud, "How will I do away with that cursed innocent lamb who stands in the way of my nefarious plot?" He dramatically raises a finger in the air as if to say, I've got it, "An ice bullet! It will melt away leaving no evidence of my crime. Oh, but curses, they're too fragile."

He subsides back into his chair, a black wrapped package of bubbling wickedness spitting out horrible thoughts, " Perhaps if I add something to it to make it harder. Sugar? No. Sawdust? Maybe, but suspicious. Ah hah! I have it now. I shall use a bullet, but a smaller caliber one. I will freeze it in the ice which then becomes an undetectable discarding sabot. Because of the difference in size it won't lead the police to my weapon, but to whatever one the smaller bullet came from. Oh, you are masterfully evil you wonderful evil genius you. I'd have your children if it were biologically possible."

And so our villain heads for the basement to prepare his plot against all that is good and right in the world, but will it succeed?
