Having knocked on the door of the Liemar Detective Agency, Charles saw a girl about Silvie's age in a small room by the door, who greeted him with a smile, "May I ask what business you have here, sir?"
Charles glanced at the nameplate on the desk: Miss Melmi, Trainee Detective, graduated from the National Academy.
He smiled faintly and said, "I'd like to consult with Miss Vinnie Yarsaenu. I don't have an appointment, but we know each other, my name is Charles Meklen."
Melmi pulled a rope inside the room. In the Fars Empire, where telephones and telegraphs didn't exist, indoor communication was a bit quirky, like this rope-pulling method which could transmit different messages through various signals.
However, in the powerful countries of the Old Continent, magic alchemy communication devices were used, and though they weren't as convenient as telegraphs and telephones for long distances, the reach was sufficiently long.
