Mysterious Cases 2

My name is Zhao Yiming, I am twenty-five years old, and I am the exclusive assistant to the owner of a private detective agency, Jerry Yan. No one in the circle dared to call him by his name. Evil people would wake up in the middle of the night when hearing his name, and gave him the nickname Guijianchou. All the clients who came to ask for help in solving the case were respectful and called him Yan Detective. Only I, who stayed with him day and night, called him Brother Yan.
