Poisonous Snake in the Mansion: The Heir’s Counterattack

My father’s sudden death after a severe illness left a massive void — both in the cold mansion and on the Chairman’s seat of Royal Enterprises. According to his will, I — Harper, his only biological daughter — became the legal heir to 65% of the shares. My stepmother, Margaret, only received a small portion of the assets and the right to live in the mansion.

When the will was announced, Margaret didn’t show a hint of anger. On the contrary, she hugged me tightly, tears streaming down her face: “My sweet girl, from now on, I will take care of you in your father’s place. We only have each other now.” The facade of a devoted stepmother, a pitiful widow, was built flawlessly.

But that was also when my “illness” began.

A few weeks after the funeral, I frequently fell into a strange, sluggish state — not exactly fatigue, but a heaviness from within, as if my brain were wading through mud. The numbers on the financial reports started dancing before my eyes. My short-term memory became terrifyingly bad — I would stand in the middle of the boardroom, forgetting what I was saying after just two sentences. Slow reflexes. Slight hand tremors in the morning.

Margaret was always by my side. She invited Dr. Lewis — the family doctor who had served our family for over a decade — to examine me. He diagnosed me with “Severe Post-Traumatic Stress Disorder and Nervous Breakdown.” Every day, Margaret personally prepared warm water, thoughtfully bringing to my bed a handful of “vitamins and brain supplements” prescribed by Dr. Lewis.

In front of the shareholders and the staff, she sighed heavily: “She’s too young to shoulder this empire, and her health is so weak… My heart aches for her.” Just like that, she slowly seized temporary executive power under the guise of “helping her sickly stepdaughter.” As for me, I gradually sank into a fog of chemicals.

Things were pushed to the brink when I discovered I was pregnant with my first child; my fiancé was working abroad at the time. I thought this little life would be my reason to pull myself together. But that hope was ruthlessly extinguished.

In my tenth week of pregnancy, contractions hit me like they were tearing my insides apart. Blood stained the bedsheets red. I miscarried.

Dr. Lewis stood by my hospital bed, his face terrifyingly calm, explaining that my body was too weak and my mental state too unstable to keep the baby. Margaret held me and sobbed, perfectly playing the role of a mother devastated by the loss of her grandchild.

I believed them, until that fateful night three days later.

That evening, Margaret brought my medicine and a glass of warm water into my room as usual. The physical pain and emotional emptiness left me paralyzed — I nodded and closed my eyes without taking them immediately. When she left, I sat up to grab the glass.

But when I looked down, I froze. The pill had accidentally slipped into the water at some point. At the bottom of the glass, it was dissolving — not evenly like a regular effervescent vitamin, but leaving a layer of cloudy white powder suspended in the water, emitting a sickly smell of medical solvent.

I sat perfectly still, staring at the glass for a long time. Even when the pill completely dissolved, the smell lingered.

A puzzle piece suddenly clicked into a void I hadn’t even known existed. The unusual sluggishness. The cognitive decline. The violent uterine contractions in my tenth week. It all started when I began taking the pills handed to me by Margaret and prescribed by Dr. Lewis.

I didn’t scream. I didn’t run to find her and confront her. Because I knew — without evidence, someone deemed “mentally unstable” like me would only be digging my own grave.

From that night on, I officially became an actress in my own home.

Every day, when Margaret brought the pills in, I pretended to obediently swallow them — but I was actually hiding them under my tongue, then spitting them out and wrapping them in a tissue when she turned her back. I slowly accumulated them in a small plastic bag hidden inside the sole of a shoebox.

Stopping the medication caused physical reactions as my body withdrew from the chemicals. My hands trembled in the mornings, I broke into cold sweats at night, and my eyes remained glazed for a few days before gradually recovering. Ironically, those genuine symptoms helped me maintain the facade of the sickly heir. Margaret and Dr. Lewis suspected absolutely nothing.

I knew I couldn’t handle this alone. Dr. Lewis was her complicit shield — there wasn’t a major hospital in the city center I could trust. I remembered Lauren — a nurse working at a small suburban private clinic who had cared for my father in the early days of his illness, before Margaret brought Dr. Lewis in. Lauren was straightforward, despised deceit, and took medical ethics incredibly seriously.

Taking advantage of an afternoon when Margaret was out for a meeting, I used a burner phone hidden in a shoe sole to call Lauren and make an appointment. That evening, I used the excuse of craving porridge in the suburbs — a habit I had before my “illness” — and insisted the driver take me. In a secluded alley, I met her.

Trembling, I handed her the plastic bag of strange pills, along with a small vial of blood I had drawn myself by sticking a needle into my wrist vein. “Lauren, help me run an independent test on these two samples. Don’t let Dr. Lewis or any major downtown hospital find out.”

She looked at me for a long time, then nodded, without asking a single question.

A few days later, I asked her to help me order a micro-voice recorder and deliver it to me next time under the guise of food delivery — along with the test results. No strange packages were sent to the house, and my name wasn’t on any invoices.

At three in the morning, while the whole house was asleep, I tiptoed into my father’s study — which Margaret now used as her main office. I carefully taped the tiny recorder under the thick oak desk, tucked right against the inner edge.

The trap was set. All that was left was patience.

A week passed. Lauren secretly sent the test results to my burner phone. The paper confirmed: those “vitamins” were actually a mixture of a high-dose benzodiazepine sedative — which depresses the central nervous system, impairs short-term memory, and causes prolonged lethargy — combined with a uterine-contracting agent strictly prohibited for pregnant women. My blood sample confirmed that the concentration of these two substances exceeded normal therapeutic levels multiple times over.

She had intentionally taken my child’s life.

That same day, when I sneaked in to retrieve the recorder, I captured an invaluable conversation between Margaret and Dr. Lewis.

Dr. Lewis’s voice: “The paperwork is done. I’ve signed the certificate of civil incapacitation. Tomorrow at the extraordinary shareholders’ meeting, you just need to present it to rightfully take over the guardianship of her assets.”

Margaret’s voice: “Well done. I was worried her pregnancy would complicate the inheritance. Who knew the drug you chose would be so… versatile. When this is over, you’ll get the 5% shares as promised.”

I sat perfectly still in the dark, listening to that recording three times. Then I put the burner phone in my pocket, walked out, and called the family lawyer — the only person with no ties to Margaret — to arrange an emergency meeting with the Criminal Investigation Bureau early the next morning.

Monday morning, the boardroom was packed. Margaret stood at the podium, wearing an elegant black suit, holding a stack of medical records.

“Ladies and gentlemen,” her voice choked up as she dabbed her dry eyes with a handkerchief. “As you all know, the shock of losing her father and her child has completely devastated Harper. According to Dr. Lewis’s medical evaluation, she has lost her civil capacity. Although it breaks my heart, for the survival of Royal Enterprises, I am forced to submit a petition to take over executive control…”

“You don’t have to act anymore.”

The heavy wooden doors swung open. The entire boardroom gasped.

I walked in. Not in the disheveled pajamas or with the lifeless eyes of the past few months. I wore a perfectly tailored white suit, my hair pinned up neatly, the heels of my shoes clicking a steady rhythm on the floor. Behind me were two officers from the Criminal Investigation Bureau and the family lawyer.

“Harper?” Margaret stammered, the smile freezing on her lips. “What are you doing here? Your health is—”

“My health is perfectly fine, ma’am.” I smiled, a smile that didn’t reach my eyes. “I just decided to stop taking your ‘vitamins’ three weeks ago.”

Before she could react, my lawyer plugged a USB drive into the projector. The recording echoed through the dead-silent room. Every word about dropping the pills into my water, about the intentional abortion, about the plot to seize the assets — laid bare before the dozens of eyes of the shareholders.

Margaret’s face turned deathly pale. Dr. Lewis backed toward the door but was immediately blocked by the two police officers.

I threw the stack of documents stamped by the National Institute of Forensic Medicine and Lauren’s clinic onto the table. “These are the independent forensic results of my blood sample and the pills Dr. Lewis prescribed. The levels of sedatives and uterine-contracting agents in my blood exceeded safe therapeutic limits multiple times. Officers, I am officially filing charges against Margaret and Mr. Lewis for intentional assault and forced abortion.”

She had used dirty tricks to harm me, so I would use objective evidence and the law to end her.

Backed into a corner, the elegant lady’s facade collapsed completely. Margaret lunged forward, falling to her knees at my feet, grabbing the hem of my pants and sobbing: “Harper, I’m sorry! The devil made me do it! I took care of your father in his final years, after all, we are family… Please forgive me!”

Dr. Lewis clasped his hands together, begging for mercy, blaming everything on Margaret for bribing and coercing him.

I bent down and pried her clinging fingers off, slowly, one by one. I looked straight into the eyes of the person who had intentionally murdered my child.

“I do not forgive.”

The handcuffs clicked onto both their wrists. Police sirens wailed below the Royal Enterprises building as the cars rolled away, disappearing behind the gates.

That very afternoon, I convened a board of directors meeting and officially signed the dismissal of all personnel who had covertly served Margaret’s interests over the past few months — a list I had prepared in advance, based on internal documents I had quietly gathered in those final weeks. By evening, locksmiths arrived to change the entire lock and security camera system of the mansion.

I stood at the window of my father’s study, looking down at the silent, sprawling courtyard. For the first time in months, the air in the house didn’t carry the scent of medicine.

I had reclaimed my kingdom — not with bitterness or screaming, but with cold patience and undeniable evidence. The hypocritical curtain had shattered. And those hiding behind it would pay the price behind prison bars.
