It was a case from Booth's past, one that haunted him. A previously unknown suspect had left a trail of a half dozen decapitated bodies between Nevada and North Dakota, but clues had been hard to come by and eventually the case went cold. Now, it was happening again, in Booth's backyard; two decapitated bodies in two days found in isolated wilderness areas. The victims had only one thing in common; they were mutually acquainted with the man now sitting in his interrogation room.
Booth had been face to face with numerous cold blooded killers, and had questioned each of them unflinchingly, but this man was different. He couldn't put his finger on it but something about Warren Kane scared the hell out of him.
The suspect had come along willingly, allowing himself to be handcuffed with nothing more than an amused smirk, but the sword found hidden inside of his long coat was a chilling reminder of what this man really was.
He took a deep breath and finally entered the small interrogation room. "Mr. Kane, is there anything I can get for you? Something to drink?"
The powerfully built man turned his icy, blue-grey eyes on Booth, and he involuntarily shuddered, his own eyes drawn to the long, straight scar that bisected the man's right eye. "No, I don't think I want anything just yet."
He took a seat on the opposite side of the table and opened a file, laying the photos of the two headless bodies on the table for the suspect to see. "Do you recognize these men, Mr. Kane?"
"Hmmm, no, see I identify people by their faces, headless bodies are ambiguous."
"Funny guy," Booth added two additional photos, close ups of the heads, "do these help?"
A smile lit the suspect's face, and if anything, only added to his menace. "Yes, that helps tremendously, I do know these two, I did, after all, remove their heads."
The admission stunned him, had it really been so easy? "Why did you kill them?"
He seemed to contemplate how to answer the question before shrugging. "It's the game, no hard feelings."
"The game, Mr. Kane?"
"Tell me, Agent Booth, have you ever killed anyone?"
"This isn't about me, Mr. Kane, it's about you, and why you would cut someone's head off."
The cold eyed suspect leaned back in his chair completely ignoring Booth's response. "You have. I can see it in your eyes. You want to pretend that you are the good guy, that you only do what is necessary, but that isn't the case. Is it?"
"Tell me about the game, Mr. Kane." Another statement ignored.
"When you killed those men, you felt satisfaction, and now you punish yourself for your feelings. Even in law enforcement, you believe that the world is black in white, even with everything you have done." He laughed, low, and grating. "How does it feel to see yourself as a villain, Agent Booth?"
That was enough to send Booth over the edge, his anger getting the better of him. "You know nothing about me, Mr. Kane."
"I beg to differ, I know more about you than you can imagine. I know your kind."
Booth shook his head; this interview was getting weirder and weirder. "The game, explain the game to me."
"All in good time, and right now is not a good time."
In irritation, Booth made a fatal mistake; he turned his back on Warren Kane, the man that he suspected of killing at least eight people by decapitation. The man that Booth had erroneously assumed was still handcuffed to his chair.
It was a matter of an instant before Booth felt a sharp object jabbing his back. Where had the knife come from?
Warren Kane thrust the knife between Agent Booth's ribs, puncturing his left lung and nicking his heart.
The last thing he heard before losing consciousness was a whispered statement. "Next time we meet, you will call me Kronos."
