A nurse confesses that she saw a man enter the operating room- but that she could not see his face because he was wearing a surgical mask. She suspects it was Dr. Sahil because the man walked like Dr. Sahil, with a limp. It is also revealed the victim was in the process of changing his will to commit more money to his family instead of Dr. Sahil. As all the clues begin to point to the doctor, could CID be close to solving the case?
