It's a combination of hard logic and romantic fantasy.
"Mr. Holmes, the east wind is coming soon." "Are you going to leave? I think this is not a good choice." "No, stay." "Very good." Serious drama style, no spoofing. Reasoning is the main line, and the emotional line is the supplement. Strange storms, a world in chaos, and ever-cruel murders. Police and detectives are at odds with each other. A highly intelligent "life mentor" and an astute "student". The two work together to solve the case and save the people from dire straits. "Who are you?" "Sherlock Holmes." "Impossible, Mr. Holmes is not as annoying as you." "..."
