Here is a plot that might unfold in a thriller novel. Here are some ways that characters might be silently injured in dramatic scenes: 1. **Stunning or vertsどこsoda**: Sneaking up and using something like verts Miche-su or clamps, or makeshift objects like steel pipes to render someone unconscious. 2. **Asphyxiation**: Quietly strangling someone using a noose, lifting cord, or clothing like scarves, ties, or socks. 3. **Faulty injection**: Using medical expertise or pharmacy knowledge to create a seemingly harmless drug or treatment that actually has a harmful or fatal effect on someone. 4. **Rapid toxic contact**: Maintaining a potentially toxic substance to make it look like an accident or natural phenomenon, such as using a concealed needle or an infected needle through skin contact. 5. **Injured bent bones**: Secretly creating fractures or repeated joint dislocations with loose bones to make the victim more susceptible to accidental or "unintentional" injuries. 6. **Fake Medical Emergency**: Taking someone to the hospital to treat an emergency, but in reality the medical procedure injures them or provides the wrong treatment, delaying a proper diagnosis. 7. **Fake Experiment**: Setting up a fake experiment to prove harmless substances, only to have real harm "accidentally" occur. 8. **Toxic Cosmetics**: Making common objects like gloves, mittens, or candies contain toxic substances that quietly paralyze or injure someone. You can use these ideas in your story to heighten the thrill and suspense of the plot and make the reader question what they think happened.
