<Game Introduction>

“When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth.”

——Sherlock Holmes

This game is an immersive mystery and deduction experience, powered by the latest large-scale AI model technology and offering a completely new form of interaction. As Sherlock Holmes, you will engage in battles of wits with dozens of AI-driven characters, uncover clues, and solve intricate puzzles. Every clue must be obtained by you—the renowned master detective—through conversations, interrogations, emotional persuasion, exploration, and deduction.

Whether major or minor, every character has a complete backstory, personality, experiences, and relationships, and will respond to your questions with real-time emotional expressions and reactions. The unprecedented immersion will make you feel as if you have been transported back to 19th-century Victorian London, where you—and only you—can alter the course of the story as the great detective Sherlock Holmes.

<Storyline>

On the mist-shrouded outskirts of 19th-century London lies the mysterious Baskerville Manor. The corpse of Sir Charles Baskerville is discovered in a nearby marsh—eyes wide open, hand clutching his chest, his face frozen in terror. There are no visible wounds, but the ground bears the tracks of a monstrous hound.

“It must be—the Baskerville curse! That demonic hound has returned!”

“Am I doomed to this fate too? No… I don’t want to die—Ahhhhh!”

Shadows loom within the manor, while danger festers beyond its walls. A suffocating fear grips everyone like the hand of a demon on their throats. Soon after Holmes arrives at Baskerville Manor at the request of his friend Maud, a series of new murders erupt—mutilated bodies in the marsh, the corpse of a woman in a neighboring estate’s fountain… Are these seemingly unrelated crimes connected? What hidden truth lies behind the Baskerville curse? As the investigation unfolds, the truth begins to surface, until—

“Sherlock, you once said that every brick of Baskerville Manor whispers… Yet some secrets drown even beneath the roar of the Thames.”

“Then we’ll need sharper ears—like a certain doctor who insists on carving Christmas pudding with a scalpel.”

<Features>

====== AI Drama! Lies That Breathe ======

“Every NPC is an Oscar-worthy liar—deception flows like blood!”
NPCs are no longer just lines of code; AI breathes life into them, turning them into living, scheming individuals. They feign calm under interrogation, scramble for excuses when their lies collapse, relish gossiping about neighbors’ secrets, and shift blame onto rivals. With AI, every character feels alive—you’ll never know if they’re about to help you solve the case… or stab you in the back.

====== AI Temper! Relationships on Edge ======

“Give the wrong gift and you’re ghosted faster than a scorned lover!”
Gift a surgeon a scalpel—he’ll hail you as a soulmate. Gift the same to a young lady, and you may get slapped with a furious “Cursing me, are you?!”

AI characters react in real time, based on personality and context—blushing, raging, smirking, even drawing guns. Whether you flirt or provoke depends on how strong your survival instinct is.

And returned gifts? They might burn them… or send them back poisoned. On a stormy night, a “gift” slipped under your door could be a bloodstained love letter—or a bullet engraved with your name.

====== AI Logic! Watson’s Brain, Your Edge ======

“Truth isn’t scripted—it’s forged in sync with Watson’s AI wit!”
Toss a teacup + a medicine bottle to Watson AI, and razor-sharp dialogue erupts instantly:

Watson AI: “Sherlock! The residue in the teacup matches the powder in this bottle!”
Holmes: “So our tea was drugged. That explains why you tried to lock me up last night.”

No walkthroughs required—AI fuels your deductions.

====== AI Twists! Endings That Haunt ======

“Think catching the culprit means victory? The AI is already plotting your downfall.”
Point to the wrong suspect? Tomorrow’s headline might read: “Holmes Disgraced! Framing Scandal Exposed!”
Hide crucial evidence? Ten years later, the smirk of the “dead” baron might flash before you in a dark alley…

AI reshapes the narrative based on your words, completed tasks, gathered clues, and items—unlocking multiple endings, including one so shocking it would make Conan Doyle rise from his grave: [SPOILER REDACTED].

—Hush… do you hear the hound’s howl echoing in the marsh?
