When My Mate Marked His Mistress Before Me

Julissa arrived at ten the next morning with a leather portfolio and a smile that looked like it had been practiced in a mirror. I met her in the kitchen where the light was good and the marble counters were cold enough to keep the cake samples from melting too fast.

"Adrianna, thank you so much for trusting me with this." She set the portfolio down and pulled out fabric swatches, seating charts, sketches of centerpiece arrangements. "I want this to be perfect for you. Ten years — that's such a milestone."

"It is," I said, and poured her tea. Earl Grey, the way she liked it. Two sugars. I'd made it for her a hundred times before, but today I watched the way her fingers wrapped around the cup, the way her pulse jumped at her wrist. Nervous. Or excited. Hard to tell the difference anymore.

We tasted three kinds of cake. Vanilla bean with champagne buttercream. Dark chocolate with raspberry preserve. Lemon elderflower with honey cream. Julissa made all the right sounds, laughing at the sweetness, debating whether the lemon was too tart for a formal event. I nodded and smiled and let her talk, but I wasn't listening to her words. I was listening to the space between them, the places where her voice caught, the way she angled her body just slightly away from me when she leaned over the table.

And I was smelling her.

The suppressants were good — professional-grade, the kind you couldn't buy at a rogue market stall. But they weren't perfect. Nothing was. Under the jasmine perfume she always wore, under the floral tea and the sugar on her breath, there was something else. Chemical. Bitter. And underneath that, faint but unmistakable, the musk of an Alpha who wasn't hers to carry.

Dominick's scent clung to the hollow of her collarbone, the place where a mate's mark would sit if she had one. It pooled there, warm and possessive, in a spot no platonic friend's scent should ever reach.

I refilled her tea and made a note on the seating chart she'd drawn up. "This looks beautiful," I said. "You always know exactly what I need."

Her whole face softened. "I just want you to be happy."

"I am," I said, and meant it in a way she would never understand.

Barnaby padded into the kitchen halfway through the second hour, his nails clicking soft on the tile. He stopped in the doorway, ears forward, and stared at Julissa with that same flat, unblinking focus he'd given her for ten years. Then he growled. Low. Sustained. A sound that came from somewhere deep in his chest and didn't stop.

Julissa laughed, but it came out too high, too quick. "Oh, Barnaby. Still not a fan, huh?"

"Barnaby, enough." I kept my voice gentle, easy. I crouched down and ran my hand over his head, scratching behind his ears the way he liked. He leaned into my palm but didn't stop watching her. "It's okay, boy. Go on."

He left, but slowly, looking back over his shoulder twice before he disappeared down the hall.

Julissa shook her head, still smiling. "I don't know what I ever did to him."

"He's protective," I said. "Always has been."

She nodded and went back to the fabric swatches, but her hands were shaking just a little now, enough that the silk slipped between her fingers when she tried to smooth it flat.

I watched her for another hour. I memorized the way she touched the doorknob when she left, the faint residue her palm left behind, the same bitter chemical trace I'd been smelling all morning. I walked her to the door and hugged her goodbye, and when she drove away I stood in the foyer and counted to sixty before I moved.

Then I went upstairs to my study and pulled out the private journal I kept locked in the bottom drawer of my desk. I wrote the date at the top of a blank page. Under it, I wrote one line in careful, even script: *He has been right every time.*

I photographed the doorknob residue with my phone. Then the chair back where she'd leaned. Then the teacup rim. I labeled each photo with the time, the location, the scent profile I'd catalogued in my head. I wasn't grieving. I was building a case. Piece by piece. Scent by scent. Every trace she left behind was another nail, and I was going to use every single one.

That night at breakfast, Nala pushed her eggs around her plate and looked up at me with those serious dark eyes that were too old for her face. "Mama, why does Auntie Julissa smell wrong?"

I set my coffee down slowly. Dominick, reading something on his phone at the other end of the table, didn't even look up. "Wrong how, sweetheart?"

Nala frowned, trying to find the words. "Like… like she's wearing a mask. And Barnaby always growls at her. He never growls at anyone else."

"Barnaby's just picky," I said lightly. "And Auntie Julissa wears a lot of perfume. Sometimes that confuses noses."

Nala nodded, but she didn't look convinced. She went back to her eggs, but I could see her wolf moving behind her eyes, restless and suspicious, the way a dominant bloodline's wolf moved when something in its territory didn't belong.

She was eight years old and already sensing what every adult around her had been too blind or too arrogant to notice.

That evening, I invited her to sit beside me while I reviewed correspondence from the Lycan Council's regional trade office. I framed it as education, the kind of thing a future Alpha heir should understand. She sat very still and listened while I explained territorial jurisdiction, bloodline inheritance clauses, the legal architecture that held a pack's land together even when its leadership failed.

She absorbed it all with quiet, startling focus. She asked smart questions. She didn't ask why I was teaching her this now, three days before an anniversary that should have been a celebration, and I didn't tell her. But I was preparing her. For the world that was about to shatter. For the inheritance I was going to make sure she kept, no matter what else burned.

Later that night, after Nala was asleep and Dominick was in his study with the door closed, I went to the guest bathroom on the second floor. The one Julissa always used when she stayed late for planning sessions or girls' nights or any of the hundred innocent reasons she'd had for being in my home, in my space, for ten years.

I opened the cabinet under the sink.

The suppressants were there. Six vials, each one small and dark, compounded herbal formula with a supplier's cipher stamped into the glass. I photographed every vial. Every label. Every trace of the mark that would lead back to the black-market channel she'd been using to hide from me for a decade.

I sealed the photographs in a document envelope. I addressed it to Lycan Council Envoy Caspian Hale's office in careful, formal script, with the instruction that it was to be opened only upon my formal invocation of Sovereign bloodline grievance rights.

I couriered it through my family's private diplomatic channel before noon the next day.

I didn't cry. I didn't rage. I just built the trap, piece by piece, and waited for the perfect moment to spring it.
