Chapter 1: 潮汐下的血迹

A gray-blue fog rolled over the morning of Tangier, stitching the earth walls of the Moorish old city to the Spanish new wall like damp, coarse cloth. The gas lamps had not yet been extinguished, their昏 yellow light dragging long shadows across the wet cobblestones. The air was thick with a pungent mixture of diesel and sea wind. Salma Tazi clutched her dark gray cloak tighter, her signature rattan first-aid kit in hand, her steps unceasing. As the only licensed female emergency medic in this port city, she had long since accustomed herself to being the calm, nearly cold anomaly in a society dominated by men. She did not rely on gentleness; her tools were tweezers, suture needles, and eyes that looked straight at the essence of death.

“Miss Salma, your expertise is not needed here.” A customs inspector blocked her path, his gaze condescending as if she were merely a grease-stained handkerchief.

“Death knows neither nationality nor gender, Inspector.” Salma stopped, her voice as steady as the harbor bells. “If that body had simply stumbled into the water after drinking too much, why is there no seawater in the lungs? My duty is to confirm the cause of death, not to speculate on motive.”

The inspector’s face darkened. He stepped aside with a cold smile: “Best it be so. The tides in Tangier are swift; don’t waste time on an anonymous sailor.”

Salma did not respond. She walked past the floating corpse being dragged onto the shore. The deceased was a young sailor, his clothes tattered, his skin wax-white from prolonged immersion. The onlookers kept a polite distance, whispering among themselves with a mix of curiosity and fear. In this city where East and West converged, death meant a complex story; Salma’s task was to isolate the forensic truth from the chaos. She crouched down and deftly opened her first-aid kit. She knew well that in this era of nascent telegraphy and delayed information, official records were muddier than the sea itself. The moment the chain of evidence broke, the truth would be buried deeply. This body was on the verge of being closed as a “drowning accident.” But when her fingers touched the victim’s cold指尖, her intuition rang an alarm—this was not a simple drowning.

“Move aside. I need to take a sample.” Salma’s tone was non-negotiable to the young officer who had drawn near.

The officer hesitated and retreated a step, muttering, “Are you out of your mind? The Merchant Guild found him. Rached Alaoui was just patrolling nearby.”

Salma’s hands did not pause. Using tweezers, she pried open the victim’s right fingernails. A vibrant indigo powder lingered in the gaps. In Tangier, such dye was rarely found on ordinary sailors; it was typically used for high-end textile coloring or marking specific chemical reagents. More critically, the inside of the victim’s forearm bore fresh scratch marks. The broken skin had coagulated into a dark red, distinct from the swelling caused by seawater immersion. The direction and force of the scratches indicated a violent struggle before death, likely against a rough wooden or metal surface, not the pounding of waves.

“What are you looking for, Tazi?” A low, raspy voice came from behind. Salma did not turn, knowing it was Hamid El-Derwi, the down-on-his-luck journalist. Lately, he had been hanging around the docks more often, his nose sharper than a hunting dog’s, always sniffing out the blood scent of a story.

“Blue dye, Mr. El-Derwi.” Salma kept her head down as she continued cleaning the fingernails. “And these scratches are fresh. Seawater washes away blood, but it does not change the pattern of subcutaneous tissue tearing. If he had committed suicide or slipped, he wouldn’t have defensive injuries like these.”

Hamid leaned in, his tobacco-scented breath mixed with the stench of cheap ink. He lowered his voice, his eyes complex and troubled: “You are challenging Rached Alaoui? He is the shadow behind the Merchant Guild. In Tangier, some truths are currency for exchange, not for exposure.”

“Truth belongs to no one, Hamid.” Salma stood up, her gaze sweeping the crowd with icy coldness. “It belongs to science, and to every person who dies unjustly because of ignorance. I will write my report, whether anyone is pleased with it or not.”

Hamid sighed, lit a cigarette, and took a deep drag. In the curling smoke, his face looked even more aged and weary. “You are too naive, Salma. Your father was, too, until he ‘accidentally’ disappeared after questioning the Harbor Bureau’s accounts. You think your skills as a medic can shake the foundations of this city? This is Tangier, a breeding ground for greed and fear. Your rationality carries no weight here.”

Salma did not refute him. She thought of her father’s last black-and-white photograph, blurred by age, and that water-damaged notebook with its smudged handwriting—her only memento, and the reason she kept going. She knew Hamid was not entirely wrong. In the dark corners where the gaslight could not reach, professional competence was often the most impotent force. But in this moment, her eyes held only the corpse before her and that inexplicable streak of blue.

“I need to have this sample tested.” Salma produced a small sealed glass bottle. “This is a preliminary assessment. If my hypothesis is correct, this blue dye is a variant of Prussian Blue, recently imported from Europe and available only in the Merchant Guild’s high-level laboratories. An ordinary sailor could not acquire it on deck, unless... he went there to work, or to steal.”

Hamid’s eyes sharpened. He crushed out his cigarette with an urgent tap. “You are saying he went to Rached Alaoui’s secret warehouse? They say it’s located on the border between the Spanish quarter and the new district, storing smuggled artifacts and contraband. If the deceased was someone who went there, this isn’t a drowning—it’s a silencing.”

“Speculation, that’s all.” Salma calmly closed the box and sealed the bottle. “Without written evidence, it remains a hypothesis. But that hypothesis is enough to make me refuse to sign a ‘drowning accident’ coroner’s report.”

A sharp, rhythmic clatter of boots cut through the din of the dock. Driss Cherif appeared, flanked by several henchmen in dark uniforms. He was stocky and imposing, his face thick with unrefined flesh. His dull eyes fixed on the glass bottle in Salma’s hand, a threatening arc curling at the corner of his mouth. As an enforcer for the Guild, his duty was to ensure dirty deeds remained unknown to outsiders.

"Miss Taqi." Dris’s voice rasped like sandpaper dragging across wood. "The Guild Master has ordered the body to be handed over to the morgue. Your work is done. Hand over the vial; it is company property."

Salma straightened her back, her fingers tightening subtly beneath her cloak. She looked at Dris with fearless eyes, a calmness that bordered on arrogance.

"This is not property, Mr. Dris." Salma's voice was quiet yet clear in the hushed dockyard. "It is evidence. Under my duty, no item connected to the deceased may be removed before the forensic examination is complete. If you force its removal, you are openly obstructing official duties. As a certified paramedic, I have the right to refuse, and the right to record your obstruction and file it with the gendarmerie."

Dris’s face flushed red. He stepped forward, his massive frame nearly blocking the flickering gas lamp above. "Don't frighten me. The gendarmerie is on the Guild's payroll anyway. Give me the vial, or else I’ll say you’re a thief who stole from the scene."

"You may say so." Salma offered a cold, ironic smile. "But you can ask the people around you. Ask Mr. Hamid. Let them see who is obstructing the paramedic’s duty, and who is trying to cover up a murder. In an age where telegraph lines have reached city hall, rumors spread faster than bullets. Are you sure you want to leave a news story here?"

Dris froze. He glanced at Hamid, who was taking notes nearby, then at the curious citizens gathering to watch. Public opinion was a slow tide, but once it crested, it was a wave the Guild could not stop. His expression fluctuated several times before he gritted his teeth and pulled out a black business card, slamming it hard against Salma’s chest.

"Rashid Alawi will come to see you personally." Dris snarled. "Remember, this is a final warning. In Tangier, the rules have never been made by women."

With that, he turned and left, his heavy steps feeling like each one was pressing down on Salma’s heart.

Salma picked up the card. The handwriting was wild and scrawled, reeking of unbridled arrogance. She watched Dris’s silhouette vanish into the mist, a chill creeping through her that was colder than the sea breeze. Rashid Alawi, the power broker controlling half of Tangier’s port trade, had finally decided to step into the fray himself.

"You've got yourself into real trouble, Salma." Hamid came to stand beside her, the usual frivolity drained from his tone, replaced by worry. "Rashid is no brute. He is a cold-blooded genius. The fact that he sent Dris means he doesn't care about the body, or even the rules. What he cares about is the evidence in your hands."

"I know." Salma tucked the card away and slung her first-aid kit back over her shoulder. "So I won't give my report to the gendarmerie. I will give it to someone who can change the game—Zuhra Amrani."

At the mention of the name, Hamid’s eyes flickered, quickly settling back into calm. "The Amrani family’s daughter? She’s been confined to her house these days; not even a fly can get in or out. Are you insane? She is Rashid’s niece and his puppet. You’re going to walk into a cage to die?"

"Precisely because she is a puppet, she is the most likely point of leverage." Salma turned her gaze toward the old city, where the shadows of the high-rises were deep and profound. "Rashid sees Zuhra as a sacrifice because he believes no one is worth risking her for. But if someone proves that her silence is not voluntary, or that she holds the key to toppling Rashid, the entire board shifts. I don’t have the evidence, but I have a lead. This corpse might be the first, or it might be the last."

Hamid was silent for a moment, then lit another cigarette, the smoke swirling around them. "What are you planning? Just barge into the Amrani residence? They have guards, they have watchers. You will be spotted."

"I don't need to barge in." Salma pulled out a folded piece of paper, a distress note she had prepared earlier, unsigned, containing only a simple herbal formula—their agreed-upon code. "I just need to make Dris believe that I am about to leak the formula to a 'key figure' who happens to be the weakness Rashid fears mentioning most. Fear makes people err. Dris is already shaken. He isn’t afraid of my report; he’s afraid of the 'witness' who might be standing behind me."

"You’re gambling?" Hamid let out a bitter laugh. "You always love swimming in the deepest waters."

"In this city, the land is just as dangerous." Salma adjusted her cloak and took a step forward. "Come, Mr. Dravi. Go to the newspaper office and point your lens here. I don’t want Rashid acting in the shadows. I want every eye focused on the light."

Hamid watched her retreating figure, thin but resilient in the mist, like a spear planted in the rocks. He shook his head and followed, clutching the draft of his report in his hand—the one not yet published. The headline consisted of only four characters: *Beneath the Tides*.

The mist at the dock began to clear, and the morning light pierced the clouds, spilling onto the wet stone slabs. It illuminated the undried blood, casting it in a ghostly golden hue. Salma knew that from this moment on, she was no longer just a paramedic. She was the eye at the center of the storm, staring fixedly into the shadows deep within Tangier. The vial of blue dye in her kit lay like a time bomb, waiting to detonate. Meanwhile, Rashid Alawi sat in his office listening to Dris’s report, tapping his fingernails against the desk, the rhythm slow and dangerous.

"An ant attempting to shake an elephant," Rashid’s voice was ice-cold, a chilling glacial stream. "Salma Taqi… the daughter of that dead journalist. Interesting. Since she wants to prove her worth, give her a chance. Let her see with her own eyes how truth is buried in this city."

He rose and walked to the window, looking down over the port. Steamships in the distance sounded their whistles, the tones heavy and long, like the tolling of an ancient funeral bell.

"Tell Zahra there will be extra rations today. And have Driss tighten surveillance. If she dares pass anything out again," Rashid turned, his smile so gentle it raised the hairs on the back of the neck, "make her the second sailor to drown by accident. Remember—use the cleanest method."

Salma walked the narrow streets leading to the old city, each step landing on centuries of sediment. She felt invisible eyes upon her—through Driss's shoulders, from Rashid's window—fixed hard on her every move. She knew she had stepped into a vortex with no way back. In this age of steam and gas, progress's light did not reach every corner; darkness always lurked behind the brightest surface, waiting for prey to draw near. She touched the vial of evidence in her pocket, the cold glass seeping through the fabric into her skin. This was not the end—not even the beginning. It was the first echo of Tangier's silent testimony, sounding softly between the rise and fall of the tide, while the blood was still wet, while everyone held their breath.
