Chapter 3 - The Secret in the Green Valley

The morning sun rose, painting the sky in violent shades of orange and pink. But inside our house, the atmosphere remained dark and cold.
Caleb had left the house before dawn. He hadn't said where he was going, but his truck was gone from the driveway. Robert was in the kitchen, nursing a cup of black coffee, his face etched with deep lines of exhaustion.
"We need to get to the bottom of this, Grace," Robert said as I walked into the kitchen. "I’ve known our boy his whole life. He’s stubborn, but he’s not crazy. If he has a diary that says Katherine did those things, he believes it with his whole heart. But Katherine... she doesn't look like a killer to me. She looks like a rabbit caught in a snare."
"She says they were stepsisters, Robert," I said, leaning against the counter. "Why did Caleb never mention that? Why did Katherine never tell us she was related to Caleb's former fiancée?"
"Because Caleb didn't know," a quiet voice said from the doorway.
We turned to see Katherine standing there. She had washed her face and put on a pair of simple jeans and a sweater, but she still looked incredibly fragile. Her hands were clasped tightly in front of her.
"When I met Caleb at the engineering firm in Chicago," Katherine explained, walking into the kitchen, "I didn't know he had been engaged to Beatrice. Beatrice had cut off contact with our family a year before she died. She moved to a different part of the city, changed her number. She was... she was going through a very dark period, dealing with her art gallery and a lot of personal issues. I didn't even know she was dead until the police called me to identify her body."
She sat down at the table, staring at her hands.
"When Caleb and I started dating, he never talked about his ex. He just said he had a bad breakup in Chicago and wanted to start over in Oakhaven Springs. I didn't want to push him. By the time we got serious, I didn't think it mattered. I didn't want to bring up my own family’s tragedies. I wanted a clean slate. I had no idea... none... that his ex-fiancée was my stepsister."
"But what about the diary, Katherine?" I asked, sitting opposite her. "Caleb is a logical man. He wouldn't risk his marriage, his future, and his relationship with his family on a whim. If he has a diary with your handwriting, with details only a family member would know... how do you explain that?"
Katherine shook her head. "I can't. Unless... unless someone else wanted Caleb to hate me. Someone who knew about my relationship with Beatrice, and knew how much Caleb loved her."
"Who?" Robert asked, his eyes narrowing. "Who would want to destroy both of you like this?"
Katherine hesitated, a shadow of fear crossing her face. "There was a man. His name is Julian Vance. He is my biological cousin—my uncle's son. He’s always been... obsessed with our family’s inheritance. When my stepfather died, he left everything to me and Beatrice. If Beatrice died and I was... out of the picture... Julian would inherit the entire estate in Oakhaven Valley."
"Oakhaven Valley?" I asked, my blood turning cold. "That’s the development project Caleb’s firm is working on right now."
"Yes," Katherine said quietly. "Julian is the primary investor. He’s the one who recommended Caleb’s engineering firm for the job. He’s the one who introduced us."
The pieces of the puzzle were beginning to shift, revealing a picture far more sinister than a simple domestic dispute. This wasn't just about revenge. It was about money, manipulation, and a calculated plot to destroy two lives for a vast corporate inheritance.
Suddenly, the front door slammed open.
Caleb walked into the house. His hair was disheveled, his eyes wild. In his hand, he held a thick, leather-bound book with yellowed pages.
"You're still here," Caleb sneered, looking at Katherine. "I told you to leave."
"Caleb, stop," I said, standing up and placing myself between him and Katherine. "We know about Julian. We know about Beatrice being her stepsister. You need to listen to her, Caleb. You’re being played."
"Played?" Caleb laughed, a harsh, grating sound. He threw the leather book onto the kitchen table. It fell with a heavy thud, sliding across the wood. "Read it, Mom. Read what your perfect 'daughter' did. Read the dates. Read the threats. It’s all there. In her own handwriting."
I reached out and opened the book. The pages were filled with a tight, neat script, detailing months of torment, fear, and despair.
But as I stared at the handwriting, a strange feeling washed over me. I had received dozens of thank-you cards and recipes from Katherine over the past two years. I knew her handwriting. It was loose, flowing, with wide loops on the letters.
The writing in this diary was completely different. It was precise, mechanical, almost too perfect.
"Caleb," I said, my voice trembling as I looked up at my son. "This isn't Katherine’s handwriting."

"Of course it is!" Caleb shouted, his eyes flashing with anger. "She disguised it! Julian told me she—"
He stopped, his face freezing as he realized what he had just said.
