Here is another excerpt from my book.
Molimo leaned forward to get a better look around the side of the building at the two Orcs talking quietly at the end of the alleyway. He was pretty sure they hadn't noticed him yet; he'd always been good at hiding from the big races. As he watched the big one on the left, who Molimo called "Tusks" because he was missing one, pulled his shirt up to his neck so the other one could see his chest. As he did that the other one, "Mr. Fancy", took out a short black rod with a clear glass part in the middle and pressed it to Tusks' chest. He held it there for almost a minute, little red crystals clinking into the glass part as Tusks shuddered.
Once he was done with that Mr. Fancy pulled the glass part out of the rod, revealing it to be a glass vial with a red cap, and held it up to his eye, nodding in satisfaction he put it into his pocket and pulled out a wad of cash bigger than anything Molimo had ever seen in his short life and handed it to Tusks, who was pulling his shirt back down. Tusks took the money and glanced around to make sure no-one was watching. He slid the money into his back pocket and started toward the mouth of the alley. Molimo ducked back and hid behind a bin.
Tusks walked out of the alley without a backward glance and headed down the street with a big smile on his face, straight into a busy bar at the corner from which a bard's playing drifted just barely above the volume of the rowdy patrons. After a few minutes had passed Mr. Fancy still hadn't come out of the alley so Molimo slunk out and slowly peered around the corner. As he did he saw Mr. Fancy, or more specifically Mr. Fancy's boots. He was standing right there, just a few feet away looking down at Molimo with a smile on his face.
"How'd you like to make the kind of money I just gave him?" Mr. Fancy asked with a small smile.
Molimo almost squeaked, his big floppy green ears twitching back and forth in his agitation. Mr. Fancy took a couple slow steps back and held out his arm to guide Molimo further into the Alley.
"It'll take just a minute" said Mr. Fancy in a low voice, "and if you don't like it, you never have to do it again. What do you have to lose?"
"Will it hurt?" Molimo asked softly as he stood and cautiously walked into the ally, never facing away from Mr. Fancy.
Mr. Fancy smiled a knowing smile, "Just a little" he said. Fully aware that he'd already got Molimo.
Molimo made it to where Tusks was standing just a few minutes ago and pulled at the edges of his ragged shirt a few times before adjusting it so that one of the many holes was position over the center of his chest, "Well" he started, then swallowed and started again, "Well, go ahead then." as he held his chin up and nodded curtly.
Mr. Fancy took out the rod and slid a new glass vial into it, Molimo noticed oddly that this one had a black cap rather than a red one but didn't have time to comment on it before Mr. Fancy pressed the rod to his chest. It started off with a tingling in his fingers and Molimo wondered how he was going to hold his shirt like this if he couldn't feel his fingers anymore. Then he didn't wonder anything anymore.
Daxton, "Mr. Fancy", held the rod to the little goblin's chest for another thirty seconds after its eyes had drifted closed and then pulled it away, watching the body crumple to the ground with a barely noticeable thud. He pulled the vial out of the rod and held it up to his eye. It was a quarter of the way full of little red crystals that glittered in the dim light, almost seeming to move of their own accord. Daxton sighed and put the vial away, the goblin hadn't gotten him very much Crystal Clarity but at least he hadn't had to work hard to get it. He turned and walked out of the alleyway and into the street, away from the bar that Nelton, his latest long term mark, had just gone into.
"Not much longer for you Nelton." Daxton said to himself with a wry smile, "That little goblin saved your life tonight."
It's always hard when you're trying to decide whether or not to kill someone off. If you're going to kill someone, why? What does there death add? Are the readers already familiar with the person or is he a nobody? How do you make people care you've killed someone off? I've tried to strike as close a balance as I can manage, let me know what you think.
