Zoe, though seemingly carefree and bold, possessed surprisingly sharp intuition.

"Why do you think that?" Tiffany asked.

"Because you're not the type to meddle," Zoe whispered. "Besides, I've seen that vintage clothing ad before. I couldn't shake the feeling that the eyes behind the mask looked exactly like yours."

Zoe had hit the nail on the head. Tiffany, usually secretive, admitted frankly, "Yes, but keep it a secret."

"What the hell?" Zoe exclaimed, quickly covering her mouth.

Her guess, based purely on intuition, had been wildly accurate. The masked woman was Tiffany. Tiffany, keeping this hidden, had confided in Zoe, showing her trust and acceptance.

Zoe was touched. "Tiffany, you're so good to me!"

"There, there," Tiffany said, patting her head.

Exams loomed that week, creating tension in the class. Despite their wealthy backgrounds, these students' families highly valued education and ability. Without skills, how could they manage their future family businesses? To prepare, the students had no weekend break.

Tiffany had promised Frank a weekly visit to Treasure Tower and on-call availability for special events. However, the school's no-break policy forced her to request leave. Due to her significant contribution to Treasure Tower's profits at the last appraisal event, Frank readily granted it. While other students were disallowed leave, Sandra received a day off for her injured hand. However, instead of the hospital, she went to a dilapidated apartment building. Stan and Selena were renting there.

Approaching the building, Sandra wrinkled her nose at the terrible environment: overflowing garbage bins reeking, no elevator, and six flights of narrow, dilapidated stairs plastered with advertisements. She wouldn't have gone if it weren't for Stan and Selena.

Reaching their apartment, Sandra's disdain was evident. The place was uninhabitable, resembling a kennel. Beer bottles, cigarette butts, and old takeaway containers littered the floor. The stench was overpowering.

Selena, seeing her daughter, asked, "Sandra, how have you been? How's the plan going? When can we finally move into a big house?"

Since being evicted by Charlie, they'd squandered their money in under three days. Though accustomed to hardship before, adapting to luxury and then losing it proved unbearable. The Kelley family's comforts, and the servants' care, had spoiled them.

Sandra was furious. "You still dare ask? You failed the first two times. What use are you?"

The first attempt involved Stan wrecking Charlie's car (which had faulty brakes) into a river; Kenneth intervened. The second involved Selena obtaining a specific drug; despite being affected, Kenneth escaped and grew wary of her. This made him colder toward her and, intentionally or not, more protective of Tiffany.

This enraged Sandra. Selena felt a mix of guilt and frustration. "What should we do?" she asked.

Stan eagerly offered, "Tell me, Sandra. I promise not to disappoint you." They saw her as their only hope; her rebukes couldn't deter their placating efforts.

Sandra said coldly, "I wanted to take things slowly, but we can't wait. Mom, find Regan, the Kelley family's maid. Give her money and have her poison their food. Dad, after Regan acts, burn down their villa—a massive fire that destroys everything."

A ruthless gleam flashed in Sandra's eyes. She aimed to destroy the entire Kelley family. Tiffany's astuteness necessitated keeping her at school during the operation.

After meticulous planning, Sandra left a card with money Charlie had given her. The next day, Selena acted.

Regan Ortega, the Kelley maid, routinely shopped for groceries. Selena waited and intercepted her.

"Oh, Regan! What a coincidence! I didn't expect to see you," Selena said, abandoning her usual arrogance. She grabbed Regan's hand and asked for a favor.

Regan asked what the favor was. Selena, feigning warmth and politeness, hinted it was to speak well of them to the Kelleys, hoping for forgiveness and reinstatement.

Selena rubbed her hands nervously. "My husband made mistakes, but blood is thicker than water. I want you to put in a good word for us. Add this mushroom to the soup; don't tell them it's from me."

Selena's dramatic sigh and tears suggested a plea for family reconciliation.

Regan, considering it a small favor with potential future benefits, agreed. Selena slipped her money.

With her part done, Stan acquired gasoline barrels, storing them in a truck. That night, Regan, feeling obliged, made clam chowder, adding the “mushroom.” Unknown to her, it was poison. (The final two paragraphs of the original text were essentially repetitions, and so have been omitted here.)
