Chapter 4 – The Eighth Door

The iron dagger lay heavy and silent on the mahogany desk, catching the flickering orange light of the hearth.

Adrien stood a few feet away, his broad, scarred chest rising and falling in shallow, ragged breaths. He had just confessed to orchestrating the ruin of seven women, to baiting my sister into his cursed labyrinth solely to drag me into his bed. He was the monster the kingdom whispered about. He had handed me the blade to end it.

I stared at the weapon. My mind reached instinctively for the tactical calculations I had spent ten years mastering at the capital’s academy—the best angle to strike a man of his mass, the precise gap between the clavicle and the carotid artery.

The void in my skull echoed back. The second door had scooped those memories out of me. I was no longer an investigator. I did not know how to hold the iron.

But I knew how to hold him.

I looked up from the dagger, meeting his pale, dilated eyes. The blue ink of the castle’s magic—what was left of it—pulsed faintly on his lower abdomen and forearms, a dark, liquid fire waiting for a conduit. I had sacrificed my pride and my past to map this curse onto my own flesh. I was not going to stop at the third door.

I turned my back on the dagger.

"I don’t want your blood, Adrien," I said, my voice hoarse but completely steady. I reached behind me, my fingers grazing the raised, burning ridges of the map now permanently etched into my spine. "I want the rest of the map."

A muscle feathered in his jaw. The vulnerability of his confession hardened instantly back into the glacial, terrifying pragmatism of the Duke of Bleu. He stepped away from the hearth, scooping his discarded linen shirt off the floor, though he did not put it on.

"Then follow," he commanded, his voice a low vibration that shook the floorboards.

We walked back into the freezing, vaulted spine of Château Barbe-Bleue. The temperature drop was violent. The cold stone bit into my bare feet. My ruined wedding gown hung in torn halves, barely covering my breasts and thighs, leaving the fresh, swirling blue ink on my skin exposed to the freezing drafts. Adrien walked ahead of me, a massive, predatory silhouette in the gloom, seemingly immune to the cold.

We bypassed the first and second doors. Their heavy bronze locks were disengaged, the terrible tolls already paid.

Adrien stopped in front of the third door. "The map is on your spine," he said, not looking at me. "Press it to the wood."

I stepped past him, ignoring the magnetic, suffocating heat radiating from his bare skin. I turned around and pressed my bare back flat against the freezing oak. The connection sparked instantly. The blue ink on my spine flared, searing through my nerve endings. A line of magic bridged the gap between my flesh and the wood.

CLACK.

The third door groaned inward.

I turned and looked into the gloom. The third room was a mirror of the castle’s grand treasury, overflowing with mountains of gold, jewels, and ancient crowns. But sitting atop the highest pile of coins was a woman with my face, starved to bone, her fingers bleeding from frantically counting coins she could not eat. She did not look up. Her eyes were hollow, entirely consumed by a manic, endless greed.

The toll struck me—a sudden, sickening wave of nausea, followed by the complete, absolute evaporation of my desire for wealth. The ambition that had driven me to seek a Duchess’s title vanished, leaving a cold, empty crater in my chest. I had lost the capacity to care about my family’s estate.

I gripped the doorframe, gasping as the vertigo passed.

"She traded her freedom for the vault," Adrien said softly from the shadows. "And the castle gave her exactly what she asked for."

I slammed the third door shut. The lock ground back into place.

I turned my attention to the fourth door, mere feet away. Elise had made it to the fourth door. Adrien had said she was the closest match, that she had pushed deep into the curse before her mind broke. If she was anywhere in this nightmare, her truth was behind that lock.

I looked at my arms, my thighs, my chest. I had the handle and the map, but I did not have the fourth key.

"Where is it?" I demanded, turning to face him.

Adrien stood utterly still. His gaze dropped slowly from my flushed face to the torn opening of my gown, tracking the rapid, frantic beat of my pulse at my throat. "I told you, Sabine. You have nothing left to trade. Your mind is hollowing out. If you take the fourth key, the castle will shatter whatever is left of your sanity."

"I am not asking for your permission," I snarled.

I closed the distance between us in three long strides. The cold of the hallway was instantly obliterated by the blistering heat of his body. I didn’t wait for him to brace himself. I shoved my hands hard against his bare shoulders, pushing him backward until his spine hit the solid oak of the fourth door.

He grunted, his hands instinctively coming up to grip my waist. "Sabine—"

"Give it to me," I ordered, weaponizing the absolute disparity in our strength. I knew he could throw me across the hall with a flick of his wrist. I also knew he was starving for the exact destruction I was offering.

I dropped to my knees on the freezing stone floor.

Adrien let out a harsh, fractured sound, his hands tangling in my hair, meaning to pull me up. But the moment my fingers went to the heavy buckle of his trousers, his resistance shattered. His head fell back against the wood of the door, a ragged groan tearing from his throat.

I ripped the buttons open and freed him. He was completely rigid, thick and heavy, the veins standing out starkly against his skin. Along the very base of his length, a thick, dormant ring of blue ink waited.

I didn’t hesitate. I leaned forward and took him into my mouth.

The reaction was explosive. Adrien roared, his massive hands gripping my head, his hips bucking forward involuntarily. The heat of him was staggering, tasting of salt and copper. The moment my lips closed around the ink, the magic flared to life. It felt like swallowing liquid lightning. The blue fire surged upward from his skin, crossing the boundary of my mouth, searing a burning, intricate path down my throat and blooming across my chest.

I swallowed his groans, setting a punishing, relentless rhythm. I used my tongue, my lips, the suction of my cheeks, dragging every ounce of the magic out of his flesh. The friction was a physical negotiation of power. He was the monster who had orchestrated my ruin, and I was on my knees, completely at his mercy, yet I was the one dismantling him piece by piece.

"Enough," he gasped, his control snapping entirely.

He hauled me to my feet by my arms, spinning us around in one violent, fluid motion. He slammed my back against the heavy oak of the fourth door. The impact knocked the breath from my lungs.

He didn’t give me a chance to recover. He gripped the torn silk of my gown, ripping it completely away, leaving me entirely bare against the freezing wood. He stepped into the space between my legs, lifting me by the thighs. I wrapped my legs instinctively around his waist, crying out as the cold stone of the door bit into my flushed skin.

He aligned us and drove upward, burying himself deep inside me with a brutal, singular thrust.

I screamed, my nails digging frantically into the heavily muscled expanse of his shoulders. The intrusion was massive, stretching me to the point of agony before the pain dissolved into a blinding, white-hot rush of pleasure.

He held me pinned to the door, supporting my entire weight, his chest heaving as he stared down into my face. The ink on his lower abdomen was bleeding rapidly onto my stomach and collarbones. But as the magic peeled away from his skin, it revealed the truth he had kept hidden beneath it.

Where the blue ink vanished, grotesque, ancient scars emerged.

They were not the faint, silvery lines of sword strikes. They were deep, jagged brands—burn marks, magical necrosis, the horrific remnants of a mass slaughter. The skin across his ribs and abdomen was a twisted map of atrocities.

"What did you do?" I gasped, the physical pleasure warring with the horrific realization of what I was looking at.

"I told you," he snarled, thrusting into me with a relentless, driving tempo that made my head crack against the door. "I am a butcher, Sabine. I burned a kingdom to ash before I ever took a wife."

Every thrust was a confession. The friction forced the remaining ink to tear away from his scars, bleeding onto my chest. I sobbed, my body betraying my horror, clenching around him, milking the magic and the pleasure from him in equal measure. The raw, violent intensity of his body was obliterating my mind. He wasn’t just hiding wives; he was hiding a genocide, and the curse was feeding on his guilt.

"Take it," he commanded, his teeth grazing my jaw, his hips grinding punishingly against mine. "Take the toll."

The heat reached a critical mass. The ink pooling across my collarbones flared with a blinding intensity, solidifying into the sharp, geometric lines of the fourth key.

I climaxed with a violent, shattering force, my vision whiting out as my body clamped down on him. Adrien shouted my name, his control completely breaking as he poured into me, his orgasm triggering the final, massive surge of the transfer.

We collapsed against the door, my legs trembling so violently they slipped from his waist. He caught me, lowering me slowly to the freezing stone floor, his chest heaving against mine.

The magic cooled. The fourth key sat perfectly rendered across my collarbones.

I didn’t wait for him to help me. I pushed him back, my breath coming in ragged gasps. I scrambled to my feet, my body aching, slick with sweat and the heavy evidence of our coupling. I turned to the fourth door.

I pressed my bare chest against the bronze lock.

The blue light flashed. The heavy metal ground open.

CLACK.

I pushed the door wide and stumbled inside, ready to face whatever twisted, broken future the castle had prepared for me.

But the room was small. It was not a grand treasury or a blood-soaked courtyard. It was a stone cell, entirely empty save for a simple wooden cot.

I walked slowly into the center of the room. The air smelled of dust and stale lavender. My heart hammered against my ribs. There was no future Sabine here.

Then, I saw it.

Gleaming faintly in the sliver of light from the hallway, half-buried in the dust near the leg of the cot, was a small object.

I dropped to my knees. My trembling fingers brushed the dust away.

It was a silver hair comb. Intricately carved with the crest of the Vale family. The comb I had given Elise on her eighteenth birthday.

I picked it up, my thumb tracing the familiar metal. Beside it, etched deeply into the stone floor, were four crude scratches. A long vertical line, crossed by three short horizontal ones.

The cipher. The secret language Elise and I had invented as children when we wanted to hide messages from our tutors.

I am alive. Look deeper.

The breath caught in my throat. I stared at the scratches, the silver comb burning against my palm. Elise wasn’t a trapped future. She wasn’t an illusion built by the castle to punish me. She was real. She had survived this room, and she was still somewhere in this fortress.

"She is alive," I whispered, the words tearing out of me.

I spun around. Adrien was standing in the doorway, his silhouette blocking the light from the hall. He had pulled his trousers up, but his chest remained bare, the horrific scars of his past fully exposed now that the ink was gone.

"You didn’t kill her," I said, clutching the silver comb to my chest. "You couldn’t break her. She’s still here."

Adrien looked at the scratches on the floor, then up at my face. His pale eyes were completely unreadable. "I never said I killed her, Sabine. I said she failed to break the curse."

"Where is she?" I stepped toward him, the cold, hard fury finally piercing through the haze of the magic. "You used her to bait me. You manipulated my entire life, you stripped my memory, you branded me with your sins. Where is my sister?"

"She is beyond the doors," he replied flatly.

"Then let me through."

"There are no more doors for you," he said, stepping into the cell, his sheer density crowding the small space. "You have four keys. The remaining three are locked behind conditions you cannot meet without dying."

"I am not leaving without her."

I stopped inches from him, tilting my head back to meet his gaze. The air between us grew impossibly thick, crackling with an electrical charge that made the hairs on my arms stand up. The magic of Château Barbe-Bleue was listening. It fed on friction. It fed on the space between us.

"You want me to find her," I realized, the truth hitting me with a sudden, sharp clarity. "You orchestrated all of this, you dragged me into your bed, not to break you out, but to let me in. You want me to find her so she can kill you for what you did."

Adrien’s jaw tightened. "Do not flatter yourself, little investigator."

"I am not an investigator anymore!" I shouted, slamming my hands against his scarred chest. "You took that from me! All I have left is the truth. And the truth is, you hate yourself more than the kingdom hates you. You want me to end you."

He grabbed my wrists, his grip bruising, pulling me flush against his body. The fury in his eyes was absolute, terrifying, and completely stripped of all defense.

"I want you to map this curse so you can walk out of this castle alive," he snarled, his voice a violent, tearing sound that echoed off the stone. "I want you to take your sister and leave me to the rot I built."

Silence slammed down on the room.

Two truths. Two completely opposing, entirely honest, raw confessions bleeding into the air at the exact same moment. I wanted his destruction. He wanted my survival.

The castle groaned.

It was a deep, structural sound, as if the very foundations of the mountain were shifting. The stone beneath our feet vibrated violently. Adrien released my wrists, spinning around to look at the hallway.

I stepped out of the cell behind him, clutching the silver comb.

In the center of the Hall of Doors, in the empty, freezing space between the fourth and fifth chambers, the air was tearing open.

A line of brilliant, blinding blue light sliced vertically from the ceiling to the floor. The light widened, shifting, solidifying until it formed the shape of a massive archway.

It was a door.

But it was not made of dark, polished oak. It was made of shimmering, distorted air, glowing with the raw, unfiltered magic of the curse. It had no handle. It had no heavy bronze lock plate.

The Eighth Door.

The legend whispered that Bluebeard’s castle had seven doors. But the magic reacted to the absolute, stripped-down honesty of our opposing wills.

I took a step toward it. My heart was hammering a frantic rhythm in my throat. The Eighth Door had no lock. It didn’t require ink. It didn’t demand a toll of my past or my future.

"Elise," I breathed, reaching my hand out toward the shimmering barrier. If she was beyond the doors, this was the path.

I pressed my palm against the light, fully expecting the door to swing open, to grant me passage into the heart of the curse to find my sister.

The door did not yield to my touch.

Instead, with a concussive boom that shattered the silence of the hall, the Eighth Door swung violently open—inward.

It did not open away from us. It opened toward Adrien.

From the blinding white void beyond the threshold, massive, ethereal chains made of the same glowing blue magic lashed out like vipers. They didn’t target me. They shot past me, slamming into Adrien’s broad chest.

He roared, a sound of absolute, helpless agony, as the chains wrapped brutally around his throat and his wrists.

The force of the magic yanked him backward, tearing him off his feet and slamming him to his knees on the stone floor. He fought it, his massive muscles straining against the ethereal iron, but the chains were rooted to the very core of the castle, pulling him relentlessly toward the open void.

I stumbled back in shock, staring at the man on his knees.

The realization hit me with the force of a physical blow, rearranging every assumption, every piece of evidence I had gathered.

He carried no physical keys. He couldn’t leave the castle. He was physically tethered to the magic of the doors.

Adrien Bleu wasn’t the monster keeping the missing wives locked in the dark.

He was the prisoner.
