[Bathtub Locked-Room Mystery + Espionage Murder + Explosive Twists]
A rainy night in London. A penthouse apartment.
A mathematician is found dead beside a red hiking backpack. The key is inside, the lock is outside: a perfect locked-room murder.
The victim was a cryptography genius at GCHQ, seconded to MI6 and privy to top-secret intelligence.
The intelligence agencies bury the case, destroy evidence, and smear the victim: a fetish-fueled suicide. Case closed!
But I insist on investigating!
After four hundred simulations, I have irrefutable proof of murder!
Digging deeper, I stumble upon a shocking conspiracy in the British and American intelligence circles.
He wasn't a pervert. He was silenced for knowing too much.
The red bag was a warning, and also a final testament to the truth he wrote with his life.
A locked room can be solved. The human heart is harder to read. The truth never dies!
This is a high-energy suspense novel that perfectly integrates secret room reasoning and intelligence espionage. It uses the mysterious case of the red bag in the bathtub as a guide to tear open the darkest fig leaf of the intelligence circle. At the beginning of the chapter, the absolutely secret room "locked outside and the key is under the corpse" firmly catches the eye. Four hundred simulation experiments cannot be reproduced. The suicide is realistic from the physical level, hard-core and rigorous. The protagonist Carlson and the forensic doctor Elena break through the layers of MI6 blockade, and press forward step by step in the suppression, frame-up, and pursuit. From scattered passwords, coordinates, and prime number clues, they dig out the shady story of the Red Bag Committee that shocked the world. The novel is not only about solving a murder case, but also about a confrontation between truth and power. It has a tight rhythm and constant reversals. Every foreshadowing is accurately recycled and the logic is closed and complete. The author vividly writes about the oppression of espionage, the brain-burning reasoning, and the complexity of human nature. The red bag went from a silence warning to a spiritual legacy of pursuing the truth, with a powerful ending. There is no watering or nonsense in the whole process, full of suspense and full of excitement. It is a hard-core suspense masterpiece that you can't put down once you open it.
