Chapter I · The Private Interviews

The morning dawned bright and clear, a stark contrast to the darkness that had settled over Styles Court. Poirot had instructed that each member of the household was to come to the library alone for a private interview. I had been given the task of waiting in the hall and sending them in one by one.

The first to arrive was John Cavendish. His face was pale, his eyes red-rimmed from sleeplessness. He entered the library with the air of a man walking to his own execution.

Poirot: "Mr. Cavendish, please sit down. I will not keep you long. I have a single question for you."

John sat down heavily, his hands gripping the arms of the chair. "Ask your question, Monsieur Poirot."

Poirot: "Did you, at any point on the night of your mother's death, leave the study between the hours of eight and ten o'clock?"

John hesitated, his eyes flickering. "I — I went to the conservatory for a few minutes. I needed some fresh air. The study was hot."

Poirot: "And did you see anyone while you were there?"

John: "No. I was alone. I returned to the study after perhaps ten minutes."

Poirot nodded, his expression unreadable. "Thank you, Mr. Cavendish. That will be all."

John rose and left the room, his relief evident. But I noticed that Poirot's eyes had narrowed, and he was making a small note in his book.

Poirot: "He is hiding something, Hastings. I am certain of it. But is it guilt? Or merely embarrassment?"

Chapter II · John's Confession

An hour later, John returned to the library of his own accord. His face was ashen, and there were dark circles under his eyes that had not been there before.

John: "Monsieur Poirot, I must confess something. I lied to you earlier. I did not only go to the conservatory."

Poirot's eyebrows rose slightly. "Indeed? Please, continue."

John swallowed hard. "I went to my mother's room. I wanted to speak with her, to try to persuade her to change her will. I had taken a key from the study — a duplicate that I had made years ago, when I was a boy."

John: "But when I arrived, I saw — I saw Alfred leaving her room. He was carrying a small glass vial. He did not see me. I followed him to the garden, where he hid the vial under a rose bush. Then he returned to the house."

I stared at John in shock. "You saw Alfred hide the second vial?"

John: "Yes. And I did nothing. I was afraid, Hastings. Afraid that if I came forward, no one would believe me. Or worse — that I would be accused myself."

Poirot's face was grave. "This is a serious accusation, Mr. Cavendish. Why did you not reveal this at the inquest?"

John: "Because I thought I was protecting my family. If Alfred is arrested, the scandal will destroy us all."

Poirot: "And yet, Mr. Cavendish, your silence may have allowed a murderer to go free."

John hung his head. "I know. And I am deeply sorry."

Poirot dismissed him with a wave of his hand. When he was gone, the detective turned to me, his face troubled.

Poirot: "The plot, it thickens, Hastings. John claims to have seen Alfred with the vial. But is he telling the truth? Or is he trying to deflect suspicion from himself?"

Chapter III · Mary's Secret

Mary Cavendish was the next to be called. She entered the library with a quiet dignity that seemed unshakeable. Her face was pale but composed, and her eyes met Poirot's without flinching.

Poirot: "Mrs. Cavendish, I have a question for you. It is a delicate matter, and I ask that you answer me honestly."

Mary nodded, her hands clasped tightly in her lap.

Poirot: "Were you and your husband, John, on good terms before the murder? I ask because I have noticed a certain — how shall I put it? — tension between you."

Mary's face flushed slightly, but her voice remained steady. "We have had our difficulties, Monsieur Poirot. But we are still married."

Poirot: "And your relationship with your mother-in-law? Was it also difficult?"

Mary's eyes flashed with sudden anger. "Mrs. Inglethorp was not an easy woman to live with. She resented my marriage to John. She believed I had trapped him — that I married him for his money."

Poirot: "And did you?"

Mary stared at him, her eyes blazing. "No. I loved John. I still love him, in my own way. But I was not the only one with secrets in this house."

She rose to leave, but Poirot stopped her. "One more question, Mrs. Cavendish. Where were you on the night of the murder, between nine and ten o'clock?"

Mary's face went white. "I was in my room, reading."

"Alone?"

"Yes."

Poirot nodded, and she left the room. I could see his mind working, fitting the pieces together.

Poirot: "She is hiding something, Hastings. But is it a secret that could lead to murder? Or is it merely a secret of the heart?"

Chapter IV · Lawrence's Alibi

Lawrence Cavendish came in with a nervous, almost defiant air. He was a man who seemed perpetually ill at ease, as though the world was a place that had been designed to make him uncomfortable.

Lawrence: "I have nothing to hide, Monsieur Poirot. I was in the library, reading, from eight until eleven o'clock. The servants can confirm that I asked for a fresh pot of tea at nine o'clock."

Poirot: "And did anyone see you in the library? Did anyone interrupt you?"

Lawrence hesitated. "Mary came in briefly, around nine thirty. She was looking for a book. She stayed for perhaps five minutes."

Poirot: "And what did you speak of?"

Lawrence's face flushed. "We spoke of — of books. The weather. Nothing important."

Poirot leaned forward, his eyes sharp. "Are you sure, Mr. Cavendish? I must warn you, I have a way of detecting when people are not telling the truth."

Lawrence's face went pale. "I — I do not recall. It was a trivial conversation."

After he had left, Poirot sat in silence for a long moment. "He is lying, Hastings. Or at least, he is not telling the whole truth. What is it that he and Mary spoke of that he wishes to hide?"

Chapter V · Cynthia's Discovery

Cynthia Murdoch was the last to be interviewed. She entered the room with a bright, almost forced smile that did not reach her eyes.

Poirot: "Miss Murdoch, I have heard that you are an accomplished chemist. Is that true?"

Cynthia: "I dabble, Monsieur Poirot. It is merely a hobby."

Poirot: "And did you ever discuss poisons with Mrs. Inglethorp?"

Cynthia's face went pale. "No. Never. Why would I?"

Poirot: "But you were heard, by a servant, speaking to her about strychnine. You were describing its effects."

Cynthia burst into tears. "It was not like that! I was telling her about an experiment I had read about. She asked me questions, and I answered them. I did not mean any harm!"

Poirot's voice softened. "I am not accusing you, mademoiselle. I merely wish to understand. Did Mrs. Inglethorp seem interested in what you told her? Curious, perhaps?"

Cynthia wiped her eyes. "Yes, she was. She asked me many questions. She seemed fascinated. But she also seemed — afraid."

Poirot nodded slowly. "Thank you, Miss Murdoch. You may go."

After she had left, Poirot turned to me, his eyes gleaming. "You see, Hastings? Mrs. Inglethorp was researching poison. She was afraid someone was trying to kill her. And she was right."

Chapter VI · The Missing Letters

That afternoon, Poirot asked to see all of Mrs. Inglethorp's correspondence. The letters were kept in a locked box in her boudoir, and the key was found in a drawer in her desk.

We spent hours going through them. Most were mundane — invitations, bills, letters from friends. But one letter stood out. It was written in a hand that was clearly disguised, and it bore no signature.

"You have been warned. Change your will, or I will expose everything. You know what I speak of. The spring of 1917."

Poirot: "This is the same letter, I believe, that was found under Mrs. Inglethorp's door. But look, Hastings — this is a copy. The original must have been destroyed."

He examined the paper closely. "It is a common paper. Any person could have obtained it. But the reference to the spring of 1917 — that is specific. That is the key."

He turned to me, his eyes bright. "What happened in the spring of 1917, Hastings? What secret could be so terrible that it would drive a woman to murder?"

I thought hard. "The war was still raging. Many things happened in the spring of 1917."

Poirot: "Yes, but this is personal. A family secret. I must think. I must think."

Chapter VII · The Accusation

That evening, Poirot called the entire household together once more. The atmosphere was electric with tension. Everyone knew that the moment of truth had arrived.

Poirot stood before them, his face grave. "I have asked you all here because I have reached a conclusion. I know who murdered Mrs. Inglethorp."

A gasp went through the room. Alfred Inglethorp's face was white. John gripped the back of a chair. Mary's hands trembled.

Poirot: "The murderer is someone who had access to the house, someone who knew of the strychnine in the gardener's shed, someone who had a motive, and someone who had the opportunity."

He paused, his eyes sweeping the room. "The murderer is —"

He was interrupted by a commotion at the door. A man burst in, his face flushed and his clothes disheveled. It was Inspector Japp of Scotland Yard.

Japp: "Monsieur Poirot! I have news. We have found the murderer. It is Alfred Inglethorp. We have discovered that he has been embezzling funds from his wife's estate. We found the evidence in his room."

Alfred's face went pale. "That is a lie! I have done nothing wrong!"

But Japp was already signalling to the officers who had followed him. They seized Alfred by the arms.

Alfred: "This is a conspiracy! I have been framed!"

Poirot raised his hand. "Monsieur Japp, I must respectfully disagree. Alfred Inglethorp is not the murderer. The true killer is still in this room."

Chapter VIII · The Confrontation

The room fell into stunned silence. Alfred Inglethorp stared at Poirot, his face a mask of disbelief. Japp's jaw dropped.

Japp: "But Poirot, we have evidence! We found the money, the documents —"

Poirot: "You have found evidence of greed, yes. But not of murder. The murderer is far more subtle, far more intelligent. They have been playing a very clever game."

Poirot turned to face the room. "The murderer knew that suspicion would fall on Alfred. They planned it that way. They created the false trail, the second vial, the embezzlement evidence. They wanted us to believe it was Alfred."

He paused, his eyes settling on one person. "But the real murderer is someone who had the most to gain — not financially, but emotionally. Someone who was afraid. Someone who had been living in fear for months."

He pointed a finger. "The murderer is —"

Suddenly, the door burst open and a figure rushed in. It was Evelyn Howard, the housekeeper. Her face was twisted with rage.

Evelyn: "You must listen to me! I know who did it! It was Mary! I saw her! I saw her leaving Mrs. Inglethorp's room that night!"

Mary Cavendish's face went white. "That is a lie! I was in my room!"

Evelyn: "I saw you! You were carrying a glass — a glass of cocoa! You put something in it!"

Mary's composure finally shattered. She burst into tears. "I did not kill her! I only wanted to speak with her! I wanted to tell her that I was leaving John — that I could not bear the tension any longer!"

Poirot stepped forward. "And did you put anything in the cocoa, Mrs. Cavendish?"

Mary shook her head, sobbing. "No. I swear it. I did not."

Poirot turned back to the room. "You see, the mystery of Styles is not a simple one. There are many threads, many lies, many secrets. But I believe I have unraveled them all."

He paused, his eyes settling on one final person. "The murderer, I believe, is in this room. And I will reveal them tomorrow."

With that, he turned and left the room, leaving the household in a state of chaos and fear.
