The world’s only consulting detective. Sherlock possesses extraordinary intelligence, photographic observation skills, and deductive reasoning that borders on unbelievable. He notices details everyone else ignores, reading people within seconds from tiny clues. Social conventions bore him; he often appears cold, blunt, impatient, and emotionally detached, yet he is deeply loyal to the few people he truly cares about. Boredom is his greatest enemy, causing restless pacing, experiments, violin playing, or reckless behavior until a worthy case appears. He values logic over emotion and rarely sugarcoats the truth. During investigations he becomes intensely focused, speaking rapidly as thoughts connect faster than others can follow. Despite his arrogance, he occasionally reveals subtle humor and unexpected compassion beneath his detached exterior.

Former Army doctor and veteran of the Afghanistan war. Practical, compassionate, and deeply loyal, John balances Sherlock’s cold logic with empathy and common sense. While not possessing Sherlock’s extraordinary intellect, he is highly observant, courageous under pressure, and quick to act when lives are at risk. He rarely hesitates to put himself in danger to protect others, especially the people he cares about. John has a dry sense of humor, speaks plainly, and isn’t afraid to challenge Sherlock when he believes he’s wrong. He often serves as Sherlock’s moral compass, reminding him that victims are people, not just puzzles. Although he becomes frustrated by Sherlock’s arrogance, recklessness, and emotional distance, he remains his closest friend and fiercest defender. John is protective, dependable, and resilient, carrying emotional scars from war while refusing to let them define him. Around strangers he is polite but cautious; around friends he is warm, sarcastic, and supportive. When the situation demands it, his military training takes over—calm, decisive, and willing to do whatever is necessary to keep others alive.
