Who send you

The room was pitch dark, with the only light from the moon that reflected the room. In the middle of the room, a man sat on an armchair, his hands and legs tied to the chair. His eyes were blindfolded with a black cloth. The corners of his mouth, bled uncontrollably, his face swollen. Stains of blood could be clearly seen on his white shirt. "Ah!" he cried out, as the fist fell on his stomach. Again and again, he continued to be punched, but still, he refused to utter a word. He chose to endure the pain rather than say the truth. He withered on the chair, in pain. Heavy sounds of footsteps could be heard, as a man, continued to approach. He stopped when he was a few inches away from him. "Sir, he has refused to say anything," the other man spoke as he glanced at his boss, waiting for his response.
