I can still remember exactly how it felt for my lungs to fill with water and how I was breaths away from death. How could she just stand by and watch? Cecilia needs to feel the same way or worse. Except this time, it will end in her death. However, I must make the story seem believable to outsiders. All they will see is an innocent and worried little sister. My dear and faithful cat can help me too! I'm sure she'll be excited for revenge after the daisy poisoning accident a few months ago. I will begin my plan on a cold winter evening.
Ugh! It's impossible to see anything in this fog. Why would Kathy want me to follow her stupid cat out in the cold?
Beware of your surroundings in foggy weather.
Kathy can remember that dreadful day as clear as ever. Her sister, Cecilia, has always been distant and indifferent towards her. The feelings of distrust and revulsion between them were mutual. However, 4 months ago, Kathy had fallen into their backyard pool on a rainy day. She couldn't swim and was helplessly drowning. When she pleaded Cecilia for help, her sister continued to laugh and stand there. Cecilia even tossed her daisies (which she did special experiments on) in the pool as Kathy suffered. If not for Kathy's faithful cat who ran to a neighbor for help, Kathy would have died that day.
Hello? Is this 911? I found my sister unconscious with a head wound out in an empty park with my cat. I don't know what to do! It looks like she slipped and fell backwards because she couldn't see.
From that day forward, Kathy began to plot revenge. She had always hated her sister, but she never expected Cecilia to just stand and laugh as she was dying. She planned to make Cecilia feel the same betrayal and helplessness as she faced her death. However, she had to exact her plan in a specific way so she wouldn't get caught. The story had to be perfectly fabricated. She could even use her cat who also had a strong distaste of her sister after a peculiar case of "accidental" daisy poisoning.
Doctor, I'm awfully worried about my sister! She is the only family member I have. Could I stay with her and keep watch over her?
Exactly at the planned time, Kathy used her cat to lure her sister out into an abandoned park. She had said that if Cecilia followed the cat, there would be a pleasant surprise for her at the end. As expected, Cecilia had foolishly went out of curiosity. It was extremely foggy that evening so it was impossible to see anything clearly. As her sister stumbled and complained, Kathy came up behind her and knocked her hard in the head with a baseball bat. Cecilia fell down onto the ground unconscious.
Finally, we're alone. This is what she deserves since she betrayed me first!
With Cecilia successfully knocked unconscious, Kathy began to call emergency services to come and bring her to a hospital. Because of the weather, dangerous slips and falls were common. Furthermore, the officials would see Kathy as only being worried and caring. Kathy would carry out the rest of the plan in the hospital when they were left alone.
As the ambulance delivered Cecilia to the hospital, Kathy put on a perfect act to convince the doctor so she can stay with Cecilia overnight. The doctor, oblivious to her ill intentions, agreed to let her monitor over her sister's condition. As far as he knew, Cecilia probably fell in the icy and foggy weather and now has a dangerous concussion.
Don't worry too much. It seems that she has a concussion, so she needs to stay in the hospital at least for a night. Since there won't be a lot of staff on schedule, of course, you can stay with her!
Finally alone in the dark hospital room, Kathy let out a breath of relief as her first part of her plot went smoothly. In her hands, she ironically held a bouquet of daisies which was used as a part of her disguise. As she stared at her sister's stony face, she didn't feel any regret as the terrible memories played in her head. If Cecilia didn't treat her so horribly, perhaps, it wouldn't have had to end like this. Carefully, she fished out a bottle of poison from her backpack and walked over to Cecilia's bedside.
