Azazel and the White Queen

Before long, Richard arrived at the entrance of a casino. Just as he was about to enter the casino and win himself another round of "living expenses," he suddenly stopped and looked up at a building two or three kilometers away from the casino. More precisely, he was looking at the rooftop of that building. Someone was using Telepathy on him! Though he did not know who was using Telepathy on him, when the other party used it to lock onto him, he sensed their exact location in return.
