"Those who say life is cheap never killed for a living. There's money to be made, getting rid of softer people's problems. If you've got the coin and a living problem, I've got the solution - I can do it clean or messy, however you like. Don't worry, I'm very discrete - no one will know it was you what bought a man's death. Do we have a deal?" Cutthroat is just a name. Sometimes they slit your throat, other times they stab you in the back. Still other times they don't use a blade at all. They might strangle you, suffocate you or poison you. The poison might just be in your drink, or it might be a lot more elaborate and subtle - a combination of separate ingredients: liquid in your drink, powder in your meal and smoke from a specially prepared candle as you drift to sleep afterwards. However they do it, it's clear they've done it before. Instinct: to profit from murder
