The rain fell in sheets against the window. Detective presencia stood, staring at the body. Blood pooled around the man in the alley. Presencia knelt down, examining the scene. A single gunshot wound to the chest. The victim clutched a crumpled note in his hand. Presencia carefully pried it loose, parted. "Carnegie Hall, 9PM. B slip 3." He glanced at his watch. 8:45 PM. Presencia jogged to his car, tires screeched.
