The maid was stunned by the situation.
She looked at Susan in shock, lowering her voice as she spoke. "Miss Simpson, if you don't let go soon, she's going to die!"
A hint of murderous intent flashed in Susan's eyes. "So what if she dies? She has confessed already!"
The maid was taken aback by these words. "When did she..."
"Just now. Didn't you hear it?" Susan looked at the maid with a smile that was not quite a smile. "You and I both heard her confession. We were both so shocked that we couldn't keep an eye on her, and she committed suicide out of guilt!"
The maid was completely bewildered upon hearing this.
She had followed Susan simply because she was usually annoyed by Jenkins. Why were the butler and Peter so nice to her and not the other maids?
So, she was jealous of Jenkins.
That's why when Susan said they were going to interrogate Jenkins, she impulsively decided to follow along.
