delivering twin boys, she was gone.

The doctors called it a postpartum complication.

The phrase had the neatness of administration and none of the weight of truth.

After her death, Damian brought the boys home to the fifty-million-dollar glass mansion overlooking the water and discovered that no amount of architecture could make a house feel less haunted.

Samuel slept well, fed well, and stared at the world with steady eyes.

Mateo was different from the beginning.

He cried in sharp patterns, arched his back, stiffened his limbs, then went strangely limp afterward.

Sometimes his skin went cool enough that Lina later said it felt like he was pulling inward.

Dr.

Vela, the family physician Clara trusted, dismissed each episode with increasing impatience.

Colic.

Reflux.

Anxious first-time father syndrome.

Damian wanted to believe him because belief was less terrifying than the alternative.

Clara made belief even easier.

Aurelia’s older sister arrived three days after the funeral with expensive luggage, a low voice, and perfect timing.

She said she came to help.

She took over schedules, household staff, and calls Damian was too numb to return.

She also began dropping small, polished sentences into his day like seeds.

The babies need stability.

You cannot run a company and a nursery.

The trust has contingencies for a reason.

She never pushed hard enough to expose the shape of her ambition, but Damian felt it.

She wanted authority over the boys.

She wanted a formal role inside the Blackwood Trust while he was too shattered to object.

Then Lina came through a referral from a maternity nurse at the hospital.

She was twenty-four, working her way through nursing school, and so quiet that Clara dismissed her as furniture within an hour.

Lina did not flatter Damian.

She did not ask personal questions.

She did not drift through the house like she belonged there.

She learned the feeding schedule, washed her own mug, and watched Mateo with a concentration Damian had not seen in anyone else.

On her second day, she made one request.

She wanted to sleep in the twins’ room.

Clara pounced on it.

Creepy.

Manipulative.

Unprofessional.

Damian, exhausted and hollowed out, let suspicion dress itself up as prudence.

He installed twenty-six hidden cameras.

Now he stood from his bed so quickly the tablet nearly slipped from his hands.

He forced himself not to storm the nursery immediately.

If Clara realized he had seen her, she would destroy whatever evidence existed before dawn.

So Damian kept watching until she retreated down the hall and her bedroom door clicked shut.

Lina remained in the rocking chair with Mateo under her cardigan, one hand spread over his back as if she could feel something fragile there that nobody else had been willing to notice.

When Mateo finally settled, she placed him in the crib and sat motionless between both boys, not relaxing, simply waiting.

Damian copied the footage to three encrypted drives, sent one automatically to an off-site server his company used for litigation holds, then went downstairs barefoot through a house that suddenly felt hostile.

The nursery door was open by the time he reached it.

Lina was standing beside the changing table with a spiral notebook in one hand.

She looked up, saw his face, and went pale.

For a second Damian thought
