*Chapter 1: Invitation in the Blizzard**
The Yangtze's waves battered the hull of the *Hanjiang* cruise ship. Lu Ming stared at the gilded characters on the invitation signed by "All Parties Related to the Starlight Jewelry Case." After ten years, the clue he'd been waiting for had arrived - the envelope contained not just a ticket, but half a broken police badge engraved with "Chen Hai," his partner who died a decade ago.
As the ship entered Xiling Gorge, the PA system abruptly cut off. By the flickering flame of his vintage lighter, Lu Ming saw ship doctor Zhang Ping arguing with a man in a bowler hat waving yellowed architectural plans - the original blueprints of Starlight Jewelry Store.
At midnight, a splash echoed from the deck. Lu Ming found Zhang Ping's lab coat snagged on the railing, its pocket spilling blue gemstone fragments matching the stolen "North Star" sapphire. The corpse in the infirmary had a half-buried fountain pen in its chest, the nib engraved with "2013.12.24" - the date of the original crime.
Intern forensic pathologist Su Wan reported: "Cardiac rupture, but with burn marks suggesting electrocution before pen stabbing. His log entry at 23:59 reads 'What's coming will come' - with obvious tampering."
Lu Ming noticed rearranged heart medications and twelve passenger manifests on Zhang's desk, each tagged with crime scene photos: broken badges, lighters, jewelry designs... "Search all cabins," he ordered, clutching Chen Hai's badge until its jagged edge drew blood. "This pen matches the cap found where Chen Hai was stabbed ten years ago."
**Chapter 2: Twelve Mirrors**
In the storm-lit banquet hall, twelve passengers sat in a circle mirroring the jewelry store's security blind spots:
1. **Su Qing (38, gemologist)**: Chen Hai's fiancée who designed the North Star setting. Her left ring finger bore a faded band mark.
2. **Zhou Ming (45, contractor)**: Altered store ventilation ducts pre-heist. Carried a note: "23:45, pipe shaft."
3. **Wang Jianguo (55, retired cop)**: Original case commander who suppressed fabric evidence matching Su Qing's cheongsam from Chen Hai's nails.
Lu Ming's manifest entry showed a lighter matching his own. "Mr. Zhou," he tapped the duct plans, "Chen found sapphire shards there at your modified site. Dr. Zhang died exactly at your meeting time."
Zhou's Adam's apple bobbed: "Zhang said he knew about the renovation secrets! I only found half a badge there!" He pointed at Su Qing: "She could access the North Star case! Chen died covering for her!"
Su Qing's nails bit her palms: "Chen texted me 'North Star in pipes' before dying. I found his badge fragments and this pen..." She raised an evidence bag containing a pen cap etched "SHADOW" - the original killer's moniker.
Wang slammed his thermos: "You're all lying! Fiber evidence proves Chen struggled with two attackers that day. Lu Ming, even you're suspect - Chen's effects vanished after you quit!"
**Chapter 3: Fragments of Time**
Encrypted files revealed:
1. Su Qing bought life insurance naming Chen as beneficiary pre-heist.
2. Zhou's firm received anonymous payments matching North Star's black market value.
3. Wang's daughter abruptly emigrated post-case with mysterious $50k deposits.
A timeline synced their 2013 movements to current events: Su Qing visiting infirmary at 23:30, Zhou at pipe shaft at 23:45, Wang returning cabin at 00:15 - mirroring Zhang's death sequence.
"Su Wan," Lu Ming realized, "Zhang altered his log entry about Su Qing getting heart meds. Why would Chen have bulletproof fabric under his nails?"
The intern pointed at surveillance stills: "Before dying, Zhang was visited by a left-handed masked figure - only Zhou is left-handed."
Zhou's hat fell, revealing a burn matching Lu Ming's neck scar. "In those pipes..." he trembled, "I saw the killer wearing Chen's badge, stabbing Zhang - no, stabbing Chen..."
**Chapter 4: Lighter's Flame**
At 3 AM, Lu Ming found Su Qing clutching half a badge at the railing. "Chen argued with Zhang about the North Star that night," she wept. "Then the gloved killer came..."
Ship blueprints revealed Zhang's hidden infirmary DNA samples and twelve life insurance policies benefiting *Hanjiang Cruise Co.* - owned by Zhang himself.
Su Wan rushed in: "Zhang had sedatives matching Chen's old burns! Zhou's plans hid staff schedules - twelve positions matching twelve passengers!"
A blood-written message appeared: "Lu Ming, twelfth shadow, your turn." The twelve shadows merged into a "SHADOW" silhouette missing Chen's shape.
**Chapter 5: Twelve Shadows**
Lu Ming illuminated the truth: "The heist was a smuggling cover-up. Chen discovered the North Star replica. Zhang faked his death while smuggling the real gem through modified ducts. We've been reenacting the original timeline."
Wang revealed body armor under his uniform: "Zhang's suicide staged as murder for insurance?"
"No," Lu Ming displayed policies. "The pen wound's angle proves a right-handed killer. The true 'Shadow' hides among us - the twelfth player Chen protected."
Dawn revealed Zhang's final note: "North Star guides you. Twelve shadows become light." Lu Ming's badge glinted, its inner engraving reading: "2013.12.24 - The Twelfth Endures."
The truth: Chen and eleven accomplices orchestrated a justice scheme against a greater villain. Zhang's death exposed the decade-old conspiracy, leaving Lu Ming to guard the shadows' legacy as the Yangtze's mist cleared.
