Calamity Sepulcher
The victim was bound and gagged. Calamity could have easily killed him from a distance with a gun, but he preferred for his business to be up close and personal. Since his victim was a high-threat one - relatively skilled with hand-to-hand combat as well as proficient with knives, the assassin had checked and double-checked the bindings.
"Do you know why I'm here?" Calamity asked slowly. Of course the victim couldn't answer, although he seemed to be trying to say something through the gag - probably a plead for help. "I'm here, because you stuck your nose where it didn't belong. You meddled, Mr. Baldwin. And not only did you meddle, but you took information that wasn't yours to know, and you threatened to make it public knowledge if you weren't paid." The assassin's expression was blank, although the right side of his mouth seemed to twitch, the closest to a smile he probably ever got. "I suppose you could have gotten away with the payments, were I not willing to take care of you for quite a bit less."
Now the man was struggling as hard as he could to escape. The chair in which he was sitting rocked onto two legs, and Calamity gave it a nudge with his foot so that it fell over sideways. He made a tsk noise with his tongue as he circled the chair. "Now, now, Mr. Baldwin. You must know that this is the end for you." He knelt down so that he was closer to eye level with the man, who now had tears streaming down his face. "Any last requests?" The man screamed against the gag, but Calamity didn't care. "No? Alright then, let's get this job done."
Calamity was preparing his weapon for the death blow, when he heard a voice behind him, causing him to spin around in surprise, weapon drawn.
